Remove old todo
commit edce1072951cfcf9e5bc7fdfce4045750d254bde
Author: Marco van Wieringen <mv...@pl...>
Date: Wed Jan 9 16:10:10 2013 +0100
Fix bug #1975 new label ignored when first is duplicate.
When labelling a new volume, if an existing volume name is entered,
subsequent entries are ignored and the original one is attempted
each time.
After the first call to db_get_media_record the MediaId of the media
record is set and as such it will keep searching on MediaId instead
of using the new entered named. So clear the MediaId and set the
VolumeName and the call db_get_media_record so it will actually search
for the new name and not for the already existing mediaid of the
duplicate name entered before.

-Rescue:
-Add to USB key:
- gftp sshfs kile kate lsssci m4 mtx nfs-common nfs-server
- patch squashfs-tools strace sg3-utils screen scsiadd

-
-Document:
-- package sg3-utils, program sg_map
-- !!! Cannot restore two jobs a the same time that were
- written simultaneously unless they were totally spooled.
-- Document cleaning up the spool files:
- db, pid, state, bsr, mail, conmsg, spool
-- Document the multiple-drive-changer.txt script.
-- Pruning with Admin job.
-- Does WildFile match against full name? Doc.
-- %d and %v only valid on Director, not for ClientRunBefore/After.
-- During tests with the 260 char fix code, I found one problem:
- if the system "sees" a long path once, it seems to forget it's
- working drive (e.g. c:\), which will lead to a problem during
- the next job (create bootstrap file will fail). Here is the
- workaround: specify absolute working and pid directory in
- bacula-fd.conf (e.g. c:\bacula\working instead of
- \bacula\working).
-- Document techniques for restoring large numbers of files.
-- Document setting my.cnf to big file usage.
-- Correct the Include syntax in the m4.xxx files in examples/conf
-- Document all the little details of setting up certificates for
- the Bacula data encryption code.
-- Document more precisely how to use master keys -- especially
- for disaster recovery.

-- Possibly allow SD to spool even if a tape is not mounted.
-- How to sync remote offices.
-- Windows Bare Metal
-- Backup up windows system state
-- Complete Job restart
-- Look at rsysnc for incremental updates and dedupping
-- Implement rwlock() for SD that takes why and can_steal to replace
- existing block/lock mechanism. rlock() would allow multiple readers
- wlock would allow only one writer.
-- For Windows disaster recovery see http://unattended.sf.net/
-- Add "before=" "olderthan=" to FileSet for doing Base of
- unchanged files.
-- Show files/second in client status output.
-- Don't attempt to restore from "Disabled" Volumes.
-- Have SD compute MD5 or SHA1 and compare to what FD computes.
-- Make VolumeToCatalog calculate an MD5 or SHA1 from the
- actual data on the Volume and compare it.
-- Remove queue.c code.
-- Implement multiple jobid specification for the cancel command,
- similar to what is permitted on the update slots command.
-- Ensure that the SD re-reads the Media record if the JobFiles
- does not match -- it may have been updated by another job.
-- Add MD5 or SHA1 check in SD for data validation
-- When reserving a device to read, check to see if the Volume
- is already in use, if so wait. Probably will need to pass the
- Volume. See bug #1313. Create a regression test to simulate
- this problem and see if VolumePollInterval fixes it. Possibly turn
- it on by default.
-
-- Page hash tables
-- Deduplication
-- Why no error message if restore has no permission on the where
- directory?
-- Possibly allow manual "purge" to purge a Volume that has not
- yet been written (even if FirstWritten time is zero) see ua_purge.c
- is_volume_purged().
-- Add disk block detection bsr code (make it work).
-- Remove done bsrs.
-- Detect deadlocks in reservations.
-- Plugins:
- - Add list during dump
- - Add in plugin code flag
- - Add bRC_EndJob -- stops more calls to plugin this job
- - Add bRC_Term (unload plugin)
- - remove time_t from Jmsg and use utime_t?
-- Deadlock detection, watchdog sees if counter advances when jobs are
- running. With debug on, can do a "status" command.
-- User options for plugins.
-- Pool Storage override precedence over command line.
-- Autolabel only if Volume catalog information indicates tape not
- written. This will avoid overwriting a tape that gets an I/O
- error on reading the volume label.
-- I/O error, SD thinks it is not the right Volume, should check slot
- then disable volume, but Asks for mount.
-- Can be posible modify package to create and use configuration files in
- the Debian manner?
-
- For example:
-
- /etc/bacula/bacula-dir.conf
- /etc/bacula/conf.d/pools.conf
- /etc/bacula/conf.d/clients.conf
- /etc/bacula/conf.d/storages.conf
-
- and into bacula-dir.conf file include
-
- @/etc/bacula/conf.d/pools.conf
- @/etc/bacula/conf.d/clients.conf
- @/etc/bacula/conf.d/storages.conf
-- Possibly add an Inconsistent state when a Volume is in error
- for non I/O reasons.
-- Fix #ifdefing so that smartalloc can be disabled. Check manual
- -- the default is enabled.
-- Dangling softlinks are not restored properly. For example, take a
- soft link such as src/testprogs/install-sh, which points to /usr/share/autoconf...
- move the directory to another machine where the file /usr/share/autoconf does
- not exist, back it up, then try a full restore. It fails.
-- Softlinks that point to non-existent file are not restored in restore all,
- but are restored if the file is individually selected. BUG!
-- Prune by Job
-- Prune by Job Level (Full, Differential, Incremental)
-- modify pruning to keep a fixed number of versions of a file,
- if requested.
-- the cd-command should allow complete paths
- i.e. cd /foo/bar/foo/bar
- -> if a customer mails me the path to a certain file,
- its faster to enter the specified directory
-- Make tree walk routines like cd, ls, ... more user friendly
- by handling spaces better.
-- When doing a restore, if the user does an "update slots"
- after the job started in order to add a restore volume, the
- values prior to the update slots will be put into the catalog.
- Must retrieve catalog record merge it then write it back at the
- end of the restore job, if we want to do this right.
-=== rate design
- jcr->last_rate
- jcr->last_runtime
- MA = (last_MA * 3 + rate) / 4
- rate = (bytes - last_bytes) / (runtime - last_runtime)
-===
-- Add a recursive mark command (rmark) to restore.
-- Look at simplifying File exclusions.
-- Scripts
-- Separate Files and Directories in catalog
-- Create FileVersions table
-- finish implementation of fdcalled -- see ua_run.c:105
-- Fix problem in postgresql.c in my_postgresql_query, where the
- generation of the error message doesn't differentiate result==NULL
- and a bad status from that result. Not only that, the result is
- cleared on a bail_out without having generated the error message.
-- Implement SDErrors (must return from SD)
-- Implement continue spooling while despooling.
-- Remove all install temp files in Win32 PLUGINSDIR.
-- No where in restore causes kaboom.
-- Performance: multiple spool files for a single job.
-- Performance: despool attributes when despooling data (problem
- multiplexing Dir connection).
-- Implement wait_for_sysop() message display in wait_for_device(), which
- now prints warnings too often.
-- Ensure that each device in an Autochanger has a different
- Device Index.
-- Look at sg_logs -a /dev/sg0 for getting soft errors.
-- btape "test" command with Offline on Unmount = yes
-
- This test is essential to Bacula.
-
- I'm going to write one record in file 0,
- two records in file 1,
- and three records in file 2

-- Add the OS version back to the Win32 client info.
-- Restarted jobs have a NULL in the from field.
-- Modify SD status command to indicate when the SD is writing
- to a DVD (the device is not open -- see bug #732).
-- Look at the possibility of adding "SET NAMES UTF8" for MySQL,
- and possibly changing the blobs into varchar.
-- Test Volume compatibility between machine architectures
-- Encryption documentation
-
-Professional Needs:
-- Migration from other vendors
- - Date change
- - Path change
-- Filesystem types
-- Backup conf/exe (all daemons)
-- Detect state change of system (verify)
-- SD to SD
-- Novell NSS backup http://www.novell.com/coolsolutions/tools/18952.html
-- Compliance norms that compare restored code hash code.
-- David's priorities
- Copypools
- Extract capability (#25)
- Threshold triggered migration jobs (not currently in list, but will be
- needed ASAP)
- Client triggered backups
- Complete rework of the scheduling system (not in list)
- Performance and usage instrumentation (not in list)
- See email of 21Aug2007 for details.
-- Look at: http://tech.groups.yahoo.com/group/cfg2html
- and http://www.openeyet.nl/scc/ for managing customer changes
-
-Projects:
-- Pool enhancements
- - Access Mode = Read-Only, Read-Write, Unavailable, Destroyed, Offsite
- - Pool Type = Copy
- - Maximum number of scratch volumes
- - Maximum File size
- - Next Pool (already have)
- - Reclamation threshold
- - Reclamation Pool
- - Reuse delay (after all files purged from volume before it can be used)
- - Copy Pool = xx, yyy (or multiple lines).
- - Catalog = xxx
- - Allow pool selection during restore.
-
-- Average tape size from Eric
- SELECT COALESCE(media_avg_size.volavg,0) * count(Media.MediaId) AS volmax, GROUP BY Media.MediaType, Media.PoolId, media_avg_size.volavg
- count(Media.MediaId) AS volnum,
- sum(Media.VolBytes) AS voltotal,
- Media.PoolId AS PoolId,
- Media.MediaType AS MediaType

- LEFT JOIN (SELECT avg(Media.VolBytes) AS volavg,
- Media.MediaType AS MediaType
- FROM Media
- WHERE Media.VolStatus = 'Full'
- GROUP BY Media.MediaType
- ) AS media_avg_size ON (Media.MediaType = media_avg_size.MediaType)
- GROUP BY Media.MediaType, Media.PoolId, media_avg_size.volavg
-- Performance
- - Despool attributes in separate thread
- - Database speedups
- - Embedded MySQL
- - Check why restore repeatedly sends Rechdrs between
- each data chunk -- according to James Harper 9Jan07.
-- Features
- - Better scheduling
- - More intelligent re-run
- - Incremental backup -- rsync, Stow
-
-- Make Bacula by default not backup tmpfs, procfs, sysfs, ...
-- Fix hardlinked immutable files when linking a second file, the
- immutable flag must be removed prior to trying to link it.
-- Change dbcheck to tell users to use native tools for fixing
- broken databases, and to ensure they have the proper indexes.
-- add udev rules for Bacula devices.
-- If a job terminates, the DIR connection can close before the
- Volume info is updated, leaving the File count wrong.
-- Look at why SIGPIPE during connection can cause seg fault in
- writing the daemon message, when Dir dropped to bacula:bacula
-- Look at zlib 32 => 64 problems.
-- Fix bextract to restore ACLs, or better yet, use common routines.
-- New dot commands from Arno.
- .show device=xxx lists information from one storage device, including
- devices (I'm not even sure that information exists in the DIR...)
- .move eject device=xxx mostly the same as 'unmount xxx' but perhaps with
- better machine-readable output like "Ok" or "Error busy"
- .move eject device=xxx toslot=yyy the same as above, but with a new
- target slot. The catalog should be updated accordingly.
- .move transfer device=xxx fromslot=yyy toslot=zzz

- 1. When jobs are running and bacula for some reason crashes or if I do a
- restart it remembers and jobs it was running before it crashed or restarted
- as of now I loose all jobs if I restart it.
-
- 2. When spooling and in the midway if client is disconnected for instance a
- laptop bacula completely discard the spool. It will be nice if it can write
- that spool to tape so there will be some backups for that client if not all.
-
- 3. We have around 150 clients machines it will be nice to have a option to
- upgrade all the client machines bacula version automatically.
-
- 4. Atleast one connection should be reserved for the bconsole so at heavy load
- I should connect to the director via bconsole which at sometimes I can't
-
- 5. Another most important feature that is missing, say at 10am I manually
- started backup of client abc and it was a full backup since client abc has
- no backup history and at 10.30am bacula again automatically started backup of
- client abc as that was in the schedule. So now we have 2 multiple Full
- backups of the same client and if we again try to start a full backup of
- client backup abc bacula won't complain. That should be fixed.
-
-- regardless of the retention period, Bacula will not prune the
- last Full, Diff, or Inc File data until a month after the
- retention period for the last Full backup that was done.
-- update volume=xxx --- add status=Full
-- Remove old spool files on startup.
-- Exclude SD spool/working directory.
-- Refuse to prune last valid Full backup. Same goes for Catalog.
-- Python:
- - Make a callback when Rerun failed levels is called.
- - Give Python program access to Scheduled jobs.
- - Add setting Volume State via Python.
- - Python script to save with Python, not save, save with Bacula.
- - Python script to do backup.
- - What events?
- - Change the Priority, Client, Storage, JobStatus (error)
- at the start of a job.
-- Why is SpoolDirectory = /home/bacula/spool; not reported
- as an error when writing a DVD?
-- Make bootstrap file handle multiple MediaTypes (SD)
-- Remove all old Device resource code in Dir and code to pass it
- back in SD -- better, rework it to pass back device statistics.
-- Check locking of resources -- be sure to lock devices where previously
- resources were locked.
-- The last part is left in the spool dir.
-
-
-- In restore don't compare byte count on a raw device -- directory
- entry does not contain bytes.
-
-
-- Max Vols limit in Pool off by one?
-- Implement Files/Bytes,... stats for restore job.
-- Implement Total Bytes Written, ... for restore job.
-- Despool attributes simultaneously with data in a separate
- thread, rejoined at end of data spooling.
-- 7. Implement new Console commands to allow offlining/reserving drives,
- and possibly manipulating the autochanger (much asked for).
-- Add start/end date editing in messages (%t %T, %e?) ...
-- Add ClientDefs similar to JobDefs.
-- Print more info when bextract -p accepts a bad block.
-- Fix FD JobType to be set before RunBeforeJob in FD.
-- Look at adding full Volume and Pool information to a Volume
- label so that bscan can get *all* the info.
-- If the user puts "Purge Oldest Volume = yes" or "Recycle Oldest Volume = yes"
- and there is only one volume in the pool, refuse to do it -- otherwise
- he fills the Volume, then immediately starts reusing it.
-- Implement copies and stripes.
-- Add history file to console.
-- Each file on tape creates a JobMedia record. Peter has 4 million
- files spread over 10000 tape files and four tapes. A restore takes
- 16 hours to build the restore list.
-- Add and option to check if the file size changed during backup.
-- Make sure SD deletes spool files on error exit.
-- Delete old spool files when SD starts.
-- When labeling tapes, if you enter 000026, Bacula uses
- the tape index rather than the Volume name 000026.
-- Add offline tape command to Bacula console.
-- Bug:
- Enter MediaId or Volume name: 32
- Enter new Volume name: DLT-20Dec04
- Automatically selected Pool: Default
- Connecting to Storage daemon DLTDrive at 192.168.68.104:9103 ...
- Sending relabel command from "DLT-28Jun03" to "DLT-20Dec04" ...
- block.c:552 Write error at 0:0 on device /dev/nst0. ERR=Bad file descriptor.
- Error writing final EOF to tape. This tape may not be readable.
- dev.c:1207 ioctl MTWEOF error on /dev/nst0. ERR=Permission denied.
- askdir.c:219 NULL Volume name. This shouldn't happen!!!
- 3912 Failed to label Volume: ERR=dev.c:1207 ioctl MTWEOF error on /dev/nst0. ERR=Permission denied.
- Label command failed for Volume DLT-20Dec04.
- Do not forget to mount the drive!!!
-- Bug: if a job is manually scheduled to run later, it does not appear
- in any status report and cannot be cancelled.
-
-
-====
-From David:
-How about introducing a Type = MgmtPolicy job type? That job type would
-be responsible for scanning the Bacula environment looking for specific
-conditions, and submitting the appropriate jobs for implementing said
-policy, eg:
-
-Job {
- Name = "Migration-Policy"
- Type = MgmtPolicy
- Policy Selection Job Type = Migrate
- Scope = "<keyword> <operator> <regexp>"
- Threshold = "<keyword> <operator> <regexp>"
- Job Template = <template-name>
-}
-
-Where <keyword> is any legal job keyword, <operator> is a comparison
-operator (=,<,>,!=, logical operators AND/OR/NOT) and <regexp> is a
-appropriate regexp. I could see an argument for Scope and Threshold
-being SQL queries if we want to support full flexibility. The
-Migration-Policy job would then get scheduled as frequently as a site
-felt necessary (suggested default: every 15 minutes).
-
-Example:
-
-Job {
- Name = "Migration-Policy"
- Type = MgmtPolicy
- Policy Selection Job Type = Migration
- Scope = "Pool=*"
- Threshold = "Migration Selection Type = LowestUtil"
- Job Template = "MigrationTemplate"
-}
-
-would select all pools for examination and generate a job based on
-MigrationTemplate to automatically select the volume with the lowest
-usage and migrate it's contents to the nextpool defined for that pool.
-
-This policy abstraction would be really handy for adjusting the behavior
-of Bacula according to site-selectable criteria (one thing that pops
-into mind is Amanda's ability to automatically adjust backup levels
-depending on various criteria).
-
-
-=====
-
-Regression tests:
-- Add Pool/Storage override regression test.
-- Add delete JobId to regression.
-- Add a regression test for dbcheck.
-- New test to add bscan to four-concurrent-jobs regression,
- i.e. after the four-concurrent jobs zap the
- database as is done in the bscan-test, then use bscan to
- restore the database, do a restore and compare with the
- original.
-- Add restore of specific JobId to regression (item 3
- on the restore prompt)
-- Add IPv6 to regression
-- Add database test to regression. Test each function like delete,
- purge, ...
-
-- AntiVir can slow down backups on Win32 systems.
-- Win32 systems with FAT32 can be much slower than NTFS for
- more than 1000 files per directory.
-
-
-1.37 Possibilities:
-- A HOLD command to stop all jobs from starting.
-- A PAUSE command to pause all running jobs ==> release the
- drive.
-- Media Type = LTO,LTO-2,LTO-3
- Media Type Read = LTO,LTO2,LTO3
- Media Type Write = LTO2, LTO3
-
-=== From Carsten Menke <boo...@gm...>
-
-Following is a list of what I think in the situations where I'm faced with,
-could be a usefull enhancement to bacula, which I'm certain other users will
-benefit from as well.
-
-1. NextJob/NextJobs Directive within a Job Resource in the form of
- NextJobs = job1,job2.
-
- Why:
- I currently solved the problem with running multiple jobs each after each
- by setting the Max Wait Time for a job to 8 hours, and give
- the jobs different Priorities. However, there scenarios where
- 1 Job is directly depending on another job, so if the former job fails,
- the job after it needn't to be run
- while maybe other jobs should run despite of that
-
-Example:
- A Backup Job and a Verify job, if the backup job fails there is no need to run
- the verify job, as the backup job already failed. However, one may like
- to backup the Catalog to disk despite of that the main backup job failed.
-
-Notes:
- I see that this is related to the Event Handlers which are on the ToDo
- list, also it is maybe a good idea to check for the return value and
- execute different actions based on the return value
-
-
-3. offline capability to bconsole
-
- Why:
- Currently I use a script which I execute within the last Job via the
- RunAfterJob Directive, to release and eject the tape.
- So I have to call bconsole "release=Storage-Name" and afterwards
- mt -f /dev/nst0 eject to get the tape out.
-
- If I have multiple Storage Devices, than these may not be /dev/nst0 and
- I have to modify the script or call it with parameters etc.
- This would actually not be needed, as everything is already defined
- in bacula-sd.conf and if I can invoke bconsole with the
- storage name via $1 in the script than I'm done and information is
- not duplicated.
-
-4. %s for Storage Name added to the chars being substituted in "RunAfterJob"
-
- Why:
-
- For the reason mentioned in 3. to have the ability to call a
- script with /scripts/foobar %s and in the script use $1
- to pass the Storage Name to bconsole
-
-5. Setting Volume State within a Job Resource
-
- Why:
- Instead of using "Maximum Volume Jobs" in the Pool Resource,
- I would have the possibilty to define
- in a Job Resource that after this certain job is run, the Volume State
- should be set to "Volume State = Used", this give more flexibility (IMHO).
-
-7. OK, this is evil, probably bound to security risks and maybe not possible
- due to the design of bacula.
-
- Implementation of Backtics ( `command` ) for shell comand execution to
- the "Label Format" Directive.
-
-Why:
-
- Currently I have defined BACULA_DAY_OF_WEEK="day1|day2..." resulting in
- Label Format = "HolyBackup-${BACULA_DAY_OF_WEEK[${WeekDay}]}". If I could
- use backticks than I could use "Label Format = HolyBackup-`date +%A` to have
- the localized name for the day of the week appended to the
- format string. Then I have the tape labeled automatically with weekday
- name in the correct language.
-==========
-- Make output from status use html table tags for nicely
- presenting in a browser.
-- Browse generations of files.
-- I've seen an error when my catalog's File table fills up. I
- then have to recreate the File table with a larger maximum row
- size. Relevant information is at
- http://dev.mysql.com/doc/mysql/en/Full_table.html ; I think the
- "Installing and Configuring MySQL" chapter should talk a bit
- about this potential problem, and recommend a solution.
-- Want speed of writing to tape while despooling.
-- Supported autochanger:
-OS: Linux
-Man.: HP
-Media: LTO-2
-Model: SSL1016
-Slots: 16
-Cap: 200GB
-- Supported drive:
- Wangtek 6525ES (SCSI-1 QIC drive, 525MB), under Linux 2.4.something,
- bacula 1.36.0/1 works with blocksize 16k INSIDE bacula-sd.conf.
-- Add regex from http://www.pcre.org to Bacula for Win32.
-- Use only shell tools no make in CDROM package.
-- Include within include does it work?
-- Implement a Pool of type Cleaning?
-- Think about making certain database errors fatal.
-- Look at correcting the time jump in the scheduler for daylight
- savings time changes.
-- Check dates entered by user for correctness (month/day/... ranges)
-- Compress restore Volume listing by date and first file.
-- Look at patches/bacula_db.b2z postgresql that loops during restore.
- See Gregory Wright.
-- Perhaps add read/write programs and/or plugins to FileSets.
-- How to handle backing up portables ...
-- Limit bandwidth
-
-Documentation to do: (any release a little bit at a time)
-- Doc to do unmount before removing magazine.
-- Alternative to static linking "ldd prog" save all binaries listed,
- restore them and point LD_LIBRARY_PATH to them.
-- Document add "</dev/null >/dev/null 2>&1" to the bacula-fd command line
-- Document query file format.
-- Add more documentation for bsr files.
-- Document problems with Verify and pruning.
-- Document how to use multiple databases.
-- VXA drives have a "cleaning required"
- indicator, but Exabyte recommends preventive cleaning after every 75
- hours of operation.
- From Phil:
- In this context, it should be noted that Exabyte has a command-line
- vxatool utility available for free download. (The current version is
- vxatool-3.72.) It can get diagnostic info, read, write and erase tapes,
- test the drive, unload tapes, change drive settings, flash new firmware,
- etc.
- Of particular interest in this context is that vxatool <device> -i will
- report, among other details, the time since last cleaning in tape motion
- minutes. This information can be retrieved (and settings changed, for
- that matter) through the generic-SCSI device even when Bacula has the
- regular tape device locked. (Needless to say, I don't recommend
- changing tape settings while a job is running.)
-- Lookup HP cleaning recommendations.
-- Lookup HP tape replacement recommendations (see trouble shooting autochanger)
-- Document doing table repair
-
-
-===================================
-- Add macro expansions in JobDefs.
- Run Before Job = "SomeFile %{Level} %{Client}"
- Write Bootstrap="/some/dir/%{JobName}_%{Client}.bsr"
-- Use non-blocking network I/O but if no data is available, use
- select().
-- Use gather write() for network I/O.
-- Autorestart on crash.
-- Add bandwidth limiting.
-- When an error in input occurs and conio beeps, you can back
- up through the prompt.
-- Detect fixed tape block mode during positioning by looking at
- block numbers in btape "test". Possibly adjust in Bacula.
-- Fix list volumes to output volume retention in some other
- units, perhaps via a directive.
-- If you use restore replace=never, the directory attributes for
- non-existent directories will not be restored properly.
-
-- see lzma401.zip in others directory for new compression
- algorithm/library.
-- Allow the user to select JobType for manual pruning/purging.
-- bscan does not put first of two volumes back with all info in
- bscan-test.
-- Figure out how to make named console messages go only to that
- console and to the non-restricted console (new console class?).
-- Make restricted console prompt for password if *ask* is set or
- perhaps if password is undefined.
-- Implement "from ISO-date/time every x hours/days/weeks/months" in
- schedules.
-
-==== from Marc Schoechlin
-- the help-command should be more verbose
- (it should explain the paramters of the different
- commands in detail)
- -> its time-comsuming to consult the manual anytime
- you need a special parameter
- -> maybe its more easy to maintain this, if the
- descriptions of that commands are outsourced to
- a ceratin-file
-- if the password is not configured in bconsole.conf
- you should be asked for it.
- -> sometimes you like to do restore on a customer-machine
- which shouldnt know the password for bacula.
- -> adding the password to the file favours admins
- to forget to remove the password after usage
- -> security-aspects
- the protection of that file is less important
-- long-listed-output of commands should be scrollable
- like the unix more/less-command does
- -> if someone runs 200 and more machines, the lists could
- be a little long and complex
-- command-output should be shown column by column
- to reduce scrolling and to increase clarity
- -> see last item
-- lsmark should list the selected files with full
- paths
-- wildcards for selecting and file and directories would be nice
-- any actions should be interuptable with STRG+C
-- command-expansion would be pretty cool
-====
-- When the replace Never option is set, new directory permissions
- are not restored. See bug 213. To fix this requires creating a
- list of newly restored directories so that those directory
- permissions *can* be restored.
-- Add prune all command
-- Document fact that purge can destroy a part of a restore by purging
- one volume while others remain valid -- perhaps mark Jobs.
-- Add multiple-media-types.txt
-- look at mxt-changer.html
-- Make ? do a help command (no return needed).
-- Implement restore directory.
-- Document streams and how to implement them.
-- Try not to re-backup a file if a new hard link is added.
-- Add feature to backup hard links only, but not the data.
-- Fix stream handling to be simpler.
-- Add Priority and Bootstrap to Run a Job.
-- Eliminate Restore "Run Restore Job" prompt by allowing new "run command
- to be issued"
-- Remove View FileSet button from Run a Job dialog.
-- Handle prompt for restore job at end of Restore command.
-- Add display of total selected files to Restore window.
-- Add tree pane to left of window.
-- Add progress meter.
-- Max wait time or max run time causes seg fault -- see runtime-bug.txt
-- Add message to user to check for fixed block size when the forward
- space test fails in btape.
-- When unmarking a directory check if all files below are unmarked and
- then remove the + flag -- in the restore tree.
-- Possibly implement: Action = Unmount Device="TapeDrive1" in Admin jobs.
-- Setup lrrd graphs: (http://www.linpro.no/projects/lrrd/) Mike Acar.
-- Revisit the question of multiple Volumes (disk) on a single device.
-- Add a block copy option to bcopy.
-- Fix "llist jobid=xx" where no fileset or client exists.
-- For each job type (Admin, Restore, ...) require only the really necessary
- fields.- Pass Director resource name as an option to the Console.
-- Add a "batch" mode to the Console (no unsolicited queries, ...).
-- Allow browsing the catalog to see all versions of a file (with
- stat data on each file).
-- Restore attributes of directory if replace=never set but directory
- did not exist.
-- Use SHA1 on authentication if possible.
-- See comtest-xxx.zip for Windows code to talk to USB.
-- Add John's appended files:
- Appended = { /files/server/logs/http/*log }
- and such files would be treated as follows.On a FULL backup, they would
- be backed up like any other file.On an INCREMENTAL backup, where a
- previous INCREMENTAL or FULL was already in thecatalogue and the length
- of the file wasgreater than the length of the last backup, only thedata
- added since the last backup will be dumped.On an INCREMENTAL backup, if
- the length of the file is less than thelength of the file with the same
- name last backed up, the completefile is dumped.On Windows systems, with
- creation date of files, we can be evensmarter about this and not count
- entirely upon the length.On a restore, the full and all incrementals
- since it will beapplied in sequence to restore the file.
-- Check new HAVE_WIN32 open bits.
-- Check if the tape has moved before writing.
-- Handling removable disks -- see below:
-- Add FromClient and ToClient keywords on restore command (or
- BackupClient RestoreClient).
-- Implement a JobSet, which groups any number of jobs. If the
- JobSet is started, all the jobs are started together.
- Allow Pool, Level, and Schedule overrides.
-- Look at updating Volume Jobs so that Max Volume Jobs = 1 will work
- correctly for multiple simultaneous jobs.
-- Implement the Media record flag that indicates that the Volume does disk
- addressing.
-- Fix fast block rejection (stored/read_record.c:118). It passes a null
- pointer (rec) to try_repositioning().
-- Implement RestoreJobRetention? Maybe better "JobRetention" in a Job,
- which would take precidence over the Catalog "JobRetention".
-- Implement Label Format in Add and Label console commands.
-- Put email tape request delays on one or more variables. User wants
- to cancel the job after a certain time interval. Maximum Mount Wait?
-- Job, Client, Device, Pool, or Volume?
- Is it possible to make this a directive which is *optional* in multiple
- resources, like Level? If so, I think I'd make it an optional directive
- in Job, Client, and Pool, with precedence such that Job overrides Client
- which in turn overrides Pool.
-
-- New Storage specifications:
- - Want to write to multiple storage devices simultaneously
- - Want to write to multiple storage devices sequentially (in one job)
- - Want to read/write simultaneously
- - Key is MediaType -- it must match
-
- Passed to SD as a sort of BSR record called Storage Specification
- Record or SSR.
- SSR
- Next -> Next SSR
- MediaType -> Next MediaType
- Pool -> Next Pool
- Device -> Next Device
- Job Resource
- Allow multiple Storage specifications
- New flags
- One Archive = yes
- One Device = yes
- One Storage = yes
- One MediaType = yes
- One Pool = yes
- Storage
- Allow Multiple Pool specifications (note, Pool currently
- in Job resource).
- Allow Multiple MediaType specifications in Dir conf
- Allow Multiple Device specifications in Dir conf
- Perhaps keep this in a single SSR
- Tie a Volume to a specific device by using a MediaType that
- is contained in only one device.
- In SD allow Device to have Multiple MediaTypes
-
-- Ideas from Jerry Scharf:
- First let's point out some big pluses that bacula has for this
- it's open source
- more importantly it's active. Thank you so much for that
- even more important, it's not flaky
- it has an open access catalog, opening many possibilities
- it's pushing toward heterogeneous systems capability
- big things:
- Macintosh file client
- working bare iron recovery for windows
- the option for inc/diff backups not reset on fileset revision
- a) use both change and inode update time against base time
- b) do the full catalog check (expensive but accurate)
- sizing guide (how much system is needed to back up N systems/files)
- consultants on using bacula in building a disaster recovery system
- an integration guide
- or how to get at fancy things that one could do with bacula
- logwatch code for bacula logs (or similar)
- support for Oracle database ??
-===
-- Look at adding SQL server and Exchange support for Windows.
-- Add progress of files/bytes to SD and FD.
-- do a "messages" before the first prompt in Console
-- Client does not show busy during Estimate command.
-- Implement Console mtx commands.
-- Implement a Mount Command and an Unmount Command where
- the users could specify a system command to be performed
- to do the mount, after which Bacula could attempt to
- read the device. This is for Removeable media such as a CDROM.
- - Most likely, this mount command would be invoked explicitly
- by the user using the current Console "mount" and "unmount"
- commands -- the Storage Daemon would do the right thing
- depending on the exact nature of the device.
- - As with tape drives, when Bacula wanted a new removable
- disk mounted, it would unmount the old one, and send a message
- to the user, who would then use "mount" as described above
- once he had actually inserted the disk.
-- Implement dump/print label to UA
-- Spool to disk only when the tape is full, then when a tape is hung move
- it to tape.
-- bextract is sending everything to the log file ****FIXME****
-- Allow multiple Storage specifications (or multiple names on
- a single Storage specification) in the Job record. Thus a job
- can be backed up to a number of storage devices.
-- Implement some way for the File daemon to contact the Director
- to start a job or pass its DHCP obtained IP number.
-- Implement a query tape prompt/replace feature for a console
-- Make sure that Bacula rechecks the tape after the 20 min wait.
-- Set IO_NOWAIT on Bacula TCP/IP packets.
-- Try doing a raw partition backup and restore by mounting a
- Windows partition.
-- From Lars Kellers:
- Yes, it would allow to highly automatic the request for new tapes. If a
- tape is empty, bacula reads the barcodes (native or simulated), and if
- an unused tape is found, it runs the label command with all the
- necessary parameters.
-
- By the way can bacula automatically "move" an empty/purged volume say
- in the "short" pool to the "long" pool if this pool runs out of volume
- space?
-- What to do about "list files job=xxx".
-- Look at how fuser works and /proc/PID/fd that is how Nic found the
- file descriptor leak in Bacula.
-- Can we dynamically change FileSets?
-- If pool specified to label command and Label Format is specified,
- automatically generate the Volume name.
-- Add ExhautiveRestoreSearch
-- Look at the possibility of loading only the necessary
- data into the restore tree (i.e. do it one directory at a
- time as the user walks through the tree).
-- Possibly use the hash code if the user selects all for a restore command.
-- Fix "restore all" to bypass building the tree.
-- Prohibit backing up archive device (findlib/find_one.c:128)
-- Implement Release Device in the Job resource to unmount a drive.
-- Implement Acquire Device in the Job resource to mount a drive,
- be sure this works with admin jobs so that the user can get
- prompted to insert the correct tape. Possibly some way to say to
- run the job but don't save the files.
-- Make things like list where a file is saved case independent for
- Windows.
-- Implement a Recycle command
-- From Phil Stracchino:
- It would probably be a per-client option, and would be called
- something like, say, "Automatically purge obsoleted jobs". What it
- would do is, when you successfully complete a Differential backup of a
- client, it would automatically purge all Incremental backups for that
- client that are rendered redundant by that Differential. Likewise,
- when a Full backup on a client completed, it would automatically purge
- all Differential and Incremental jobs obsoleted by that Full backup.
- This would let people minimize the number of tapes they're keeping on
- hand without having to master the art of retention times.
-- When doing a Backup send all attributes back to the Director, who
- would then figure out what files have been deleted.
-- Currently in mount.c:236 the SD simply creates a Volume. It should have
- explicit permission to do so. It should also mark the tape in error
- if there is an error.
-- Cancel waiting for Client connect in SD if FD goes away.
-
-- Implement timeout in response() when it should come quickly.
-- Implement a Slot priority (loaded/not loaded).
-- Implement "vacation" Incremental only saves.
-- Implement create "FileSet"?
-- Add prefixlinks to where or not where absolute links to FD.
-- Issue message to mount a new tape before the rewind.
-- Simplified client job initiation for portables.
-- If SD cannot open a drive, make it periodically retry.
-- Add more of the config info to the tape label.
-
-- Refine SD waiting output:
- Device is being positioned
- > Device is being positioned for append
- > Device is being positioned to file x
- >
-- Figure out some way to estimate output size and to avoid splitting
- a backup across two Volumes -- this could be useful for writing CDROMs
- where you really prefer not to have it split -- not serious.
-- Make bcopy read through bad tape records.
-- Program files (i.e. execute a program to read/write files).
- Pass read date of last backup, size of file last time.
-- Add Signature type to File DB record.
-- CD into subdirectory when open()ing files for backup to
- speed up things. Test with testfind().
-- Priority job to go to top of list.
-- Why are save/restore of device different sizes (sparse?) Yup! Fix it.
-- Implement some way for the Console to dynamically create a job.
-- Solaris -I on tar for include list
-- Need a verbose mode in restore, perhaps to bsr.
-- bscan without -v is too quiet -- perhaps show jobs.
-- Add code to reject whole blocks if not wanted on restore.
-- Check if we can increase Bacula FD priorty in Win2000
-- Check if both CatalogFiles and UseCatalog are set to SD.
-- Possibly add email to Watchdog if drive is unmounted too
- long and a job is waiting on the drive.
-- After unmount, if restore job started, ask to mount.
-- Add UA rc and history files.
-- put termcap (used by console) in ./configure and
- allow -with-termcap-dir.
-- Fix Autoprune for Volumes to respect need for full save.
-- Compare tape to Client files (attributes, or attributes and data)
-- Make all database Ids 64 bit.
-- Allow console commands to detach or run in background.
-- Add SD message variables to control operator wait time
- - Maximum Operator Wait
- - Minimum Message Interval
- - Maximum Message Interval
-- Send Operator message when cannot read tape label.
-- Verify level=Volume (scan only), level=Data (compare of data to file).
- Verify level=Catalog, level=InitCatalog
-- Events file
-- Add keyword search to show command in Console.
-- Events : tape has more than xxx bytes.
-- Complete code in Bacula Resources -- this will permit
- reading a new config file at any time.
-- Handle ctl-c in Console
-- Implement script driven addition of File daemon to config files.
-- Think about how to make Bacula work better with File (non-tape) archives.
-- Write Unix emulator for Windows.
-- Make database type selectable by .conf files i.e. at runtime
-- Set flag for uname -a. Add to Volume label.
-- Restore files modified after date
-- SET LD_RUN_PATH=$HOME/mysql/lib/mysql
-- Remove duplicate fields from jcr (e.g. jcr.level and jcr.jr.Level, ...).
-- Timout a job or terminate if link goes down, or reopen link and query.
-- Concept of precious tapes (cannot be reused).
-- Make bcopy copy with a single tape drive.
-- Permit changing ownership during restore.

-- Autolabel should be specified by DIR instead of SD.
-- Storage daemon
- - Add media capacity
- - AutoScan (check checksum of tape)
- - Format command = "format /dev/nst0"
- - MaxRewindTime
- - MinRewindTime

-- Write a Storage daemon that uses pipes and
- standard Unix programs to write to the tape.
- See afbackup.
-- Need something that monitors the JCR queue and
- times out jobs by asking the deamons where they are.
-- Verify from Volume
-- Need report class for messages. Perhaps
- report resource where report=group of messages
-- enhance scan_attrib and rename scan_jobtype, and
- fill in code for "since" option
-- Director needs a time after which the report status is sent
- anyway -- or better yet, a retry time for the job.
-- Don't reschedule a job if previous incarnation is still running.
-- Some way to automatically backup everything is needed????
-- Need a structure for pending actions:
- - buffered messages
- - termination status (part of buffered msgs?)
-- Drive management
- Read, Write, Clean, Delete
-- Login to Bacula; Bacula users with different permissions:
- owner, group, user, quotas
-- Store info on each file system type (probably in the job header on tape.
- This could be the output of df; or perhaps some sort of /etc/mtab record.

-I noticed the subject thread and thought I would offer the following
-merely as sources of ideas, i.e. something to think about, not even as
-strong as a request. In my former life (before retiring) I often
-dealt with backups and storage management issues/products as a
-developer and as a consultant. I am currently migrating my personal
-network from amanda to bacula specifically because of the ability to
-cross media boundaries during storing backups.
-Are you familiar with the commercial product called ADSM (I think IBM
-now sells it under the Tivoli label)? It has a couple of interesting
-ideas that may apply to the following topics.
-
-1. Migration: Consider that when you need to restore a system, there
-may be pressure to hurry. If all the information for a single client
-can eventually end up on the same media (and in chronological order),
-the restore is facillitated by not having to search past information
-from other clients. ADSM has the concept of "client affinity" that
-may be associated with it's storage pools. It seems to me that this
-concept (as an optional feature) might fit in your architecture for
-migration.
-
-ADSM also has the concept of defining one or more storage pools as
-"copy pools" (almost mirrors, but only in the sense of contents).
-These pools provide the ability to have duplicte data stored both
-onsite and offsite. The copy process can be scheduled to be handled
-by their storage manager during periods when there is no backup
-activity. Again, the migration process might be a place to consider
-implementing something like this.
-
->
-> It strikes me that it would be very nice to be able to do things
-like
-> have the Job(s) backing up the machines run, and once they have all
-> completed, start a migration job to copy the data from disks Volumes
-to
-> a tape library and then to offsite storage. Maybe this can already
-be
-> done with some careful scheduling and Job prioritzation; the events
-> mechanism described below would probably make it very easy.
-
-This is the goal. In the first step (before events), you simply
-schedule
-the Migration to tape later.
-
-2. Base jobs: In ADSM, each copy of each stored file is tracked in
-the database. Once a file (unique by path and metadata such as dates,
-size, ownership, etc.) is in a copy pool, no more copies are made. In
-other words, when you start ADSM, it begins like your concept of a
-base job. After that it is in the "incremental" mode. You can
-configure the number of "generations" of files to be retained, plus a
-retention date after which even old generations are purged. The
-database tracks the contents of media and projects the percentage of
-each volume that is valid. When the valid content of a volume drops
-below a configured percentage, the valid data are migrated to another
-volume and the old volume is marked as empty. Note, this requires
-ADSM to have an idea of the contents of a client, i.e. marking the
-database when an existing file was deleted, but this would solve your
-issue of restoring a client without restoring deleted files.
-
-This is pretty far from what bacula now does, but if you are going to
-rip things up for Base jobs,.....
-Also, the benefits of this are huge for very large shops, especially
-with media robots, but are a pain for shops with manual media
-mounting.

-==============================
-
-Longer term to do:
-- Audit M_ error codes to ensure they are correct and consistent.
-- Add variable break characters to lex analyzer.
- Either a bit mask or a string of chars so that
- the caller can change the break characters.
-- Make a single T_BREAK to replace T_COMMA, etc.
-- Ensure that File daemon and Storage daemon can
- continue a save if the Director goes down (this
- is NOT currently the case). Must detect socket error,
- buffer messages for later.
-- Add ability to backup to two Storage devices (two SD sessions) at
- the same time -- e.g. onsite, offsite.
