[flexbackup-help] flexbackup | something doesn't work

[Simon M. <sim...@ch...>]

Hi,

I tried to setup flexbackup cronjobs where I pipe the output to some othe=
r
program. Unfortunately It doesn't work as I expected:

[root@backup root]# flexbackup -set snapshots -incremental | sendalert ba=
ckup
/etc/flexbackup.conf syntax OK

Did I miss something here?

Thanks,
Simon

Nope, no such facility exists now.  

It does use a numeric "index key" for each tape, so this kind of thing
could be added, perhaps like:
 
    run a command such as "flexbackup -dir xxxxxxxx -tapekey 12345678"
    when about to do a a backup
         get tape index off the drive (code already does this)
         compare to desired key
         if not equal, exit

Not all tapes drives support that operation.

Someone sent a simple suggestion the other day though 
(flexbackup <whatever> && mt offline)

I think that's just a methodology question.  Sure, you can arrange it
however you want.  "flexbackup -level 0 -erase" will wipe the tape and do a
full backup every day if you want it to.... swap the tapes as much as you
like.  As mentioned above, there is no label-checking mechanism currently.

Maybe you want to call flexbackup like this:

flexbackup -set all && mt offl

That's all you need.

[flexbackup-help] SSH Keys

Hello,

 

 I setup ssh keys, and they are working just fine, but when flexbackup runs,
it still asks for the password.

[flexbackup-help] Some FlexBackup Questions

[<cl...@vv...>]

Hi,

i'm searching for a backup tool that fit to my needs. I found Flexbackup. It seems to make really all thinks I need. But i've some questions left, which could not be answered via Docs or Mailinglist Archives.

First One:
Is it possible to define a Tapename on which the Backup Data should go. If the wrong Backup is inside the TapeDrive, no backup is made, and I recive an Error via E-Mail.

Second One:
Is it possible to throw out the Tape when backup finished successfull? One small think, but nice Feature ;o)

Third One:
I have here 12 Tapes. 6 per Week. Every Day, excluding Sunday, a Full Backup should be done, overwriting the Tape Content that exists on the Tape (if the right Tape is insight, see point 2). When Week ends the Tapes are switched. The Tapes from the 'last' week are placed in an secret Place, and the other 6 Tapes are written. When next week is gone, the Tape from the Secret Place came back, and will be used for Backups. (I hope you got me right ;o)
Is it possible with FlexBackup?

[flexbackup-help] Intermittent backup failure

[Paul F. <P....@d2...>]

Hi all. I have one particular box that fails to backup every now and
then.=20
It has a Sony DDS3 SCSI tape drive, on an Adaptec SCSI controller.

The problem is that the backup process seems to freeze, and I am unable
to completely kill it.
I have searched the net for days trying to resolve this problem, if you
could be on any assistance, it would me much appreciated.

This is how the processes appears after a failed backup.
--------------------------------------------------------
27242 ?        S      0:00 /bin/sh /sbin/e-smith/backup

27288 ?        S      0:00 sh -c ((dump -0 -b 32 -a -f - / | gzip -4) |

27294 ?        S      0:01 buffer -m 3m -s 32k -u 100 -t -p 75 -B -o
/dev/nst0

It failed on the 9th after running fine for about two weeks, the
duplicate processes are from the job trying to start the next night.


After killing the buffer process 27294 it appears like this:
------------------------------------------------------------
27294 ?        Z      0:01 [buffer <defunct>]

This makes me think it has something to do with it.
Following is a copy of the logs for the 9th, and my flexbackup.conf

Any help would be appreciated.

[flexbackup-help] Problem with labeling backups from a Windows share

[Holger K. <ku...@el...>]

Hi,

The "label" feature ($label = 'true'; in the config file) uses touch to 
create a file named with the information about the current backup job. This 
file is stored within the source tree of the files to be backed up and then 
deleted after completion.

If you backup a Windows share the filename of this file can not contain any 
colons, which are used as delimiters for the timestamp. Colons are not 
allowed in a Windows file name and touch will fail with an error message 
that the file can not be found.

As a workaround the label option in the config file can be set to "false" 
and the backup will work fine from a windows share.

To fix this I would suggest to alter the timestamp not to contain any colons.

Observed on:
-OS: Freebsd 4.9
-Flexbackup: 1.2.1

Regards,

Holger

Hard to tell what's actually wrong with just the bottom snippet.  But there
was some sort of error from find, buffer and/or afio.

You need to scroll up in the log and find the problem, or turn verbose off
to make it easier to see. (or run with "--igrnore-errors")

Use this: (the prune key is the filesystem not the set name)

 $set{'jonas'} = "/mnt/barton_jonas";

 $prune{'/mnt/barton_jonas'} = "musik film";

It's already there:

[flexbackup-help] flexbackup doesn't prune

[Jonas L. <jon...@st...>]

Flexbackup works good in many ways but I still have some problems with
my backups.

In the end of the logs I can read:

ERROR from backup, exiting
offending command(s):
cd "/" && (printf "//--/tmp/label.5968 flexbackup.volume_header_info\n"
&& find . -regex "\./\(.*_backup_\|proc\|film\|tmp\|musik\)/.*" -prune
-o -xdev ! -type s \( -newer "/var/lib/flexbackup/root.3" -or -cnewer

-Z -M 2m -T 3k -v -b 10k - | buffer -m 10m -p 75 -s 10k -t -u 100 -B -o
"/dev/nst0"

I seems to get this error regardless if I am "backuping" from a windows
share or a native linux partition.

All my configured sets aren't always accessible (due to the fact that
some machines are shutdown some nights).

I don't know if the error above is connected to my other question. How
should I get pruning to work? I wan't to exclude to directories with
large files. For the moment I have tried this:

$set{'jonas'} = "/mnt/barton_jonas";
$prune{'jonas'} = "musik film";

I want it to don't care about the dirs "musik" and "film" in the mounted
samba share "/mnt/barton_jonas"

Thanks in advance
Jonas

Actually it will work this way:

   $set{'home-fred'} = '/home/fred';
   $set{'home-wilma'} = '/home/wilma';
   $set{'home-barney'} = '/home/barney';
   $set{'home-other'} = '/home';
   
   $prune{'/home'} = "fred wilma barney";

Test it with "-type filelist" perhaps if you want to verify its doing the
correct thing before burning gigs of disk space.


In fact, you don't even need to make multiple sets (unless you specifically
want to run the jobs at different times or in parallel).  You can do:

   $set{'allhomes'} = '/home /home/fred /home/wilma /home/barney';

   $prune{'/home'} = "fred wilma barney";

And you'll still get 4 separate archives when you do "flexbackup -set allhomes".
They will run in one job, serially, and make one log file.  But 4 archive files.
Should do the exclusion correctly.

Hmm.. It doesn't let you do that right now, but its something to ponder.


Hope this helps,

"pre-backup" suggests that it has nothing to do with flexbackup itself. 
Please check your log files, and ask your question on the e-smith.org

[flexbackup-help] backing up /home

[Scott C. <sc...@bn...>]

Hello,

I have been using flexbackup for over a year now and like
it very much.

I am now planning to use it on one of our servers, which
has a lot more users and files than the other computer I
use it on.

The /home directory has about seventy users.  Four of these
users use about 6G each of the drive space.  The others
use about 6G all together.

I do my backups to a separate disk on the local computer
(and then copy the images to a second computer) and I would
like to have each of the 'big' users go into their own image
file, and then all of the others go into one other image file.

I would like to do something like this:

$set{'home-fred'} = '/home/fred';
$set{'home-wilma'} = '/home/wilma';
$set{'home-barney'} = '/home/barney';
$set{'home-other'} = '/home/"everyone-else"';

and then:

$prune{'/home'} = "fred wilma barney";

but I see that this is probably not how the 'prune' stuff works,
so this will not do what I want it to.

I need a $prune{'home-other'} = "fred wilma barney"; or some such.

Or, I need something like:

$set{'home-af'} = "/home/[a-f]*";
$set{'home-gm'} = "/home/[g-m]*";
$set{'home-ns'} = "/home/[n-s]*";
$set{'home-tz'} = "/home/[t-z]*";

Any ideas on how to do this?

Thanks,

Scott

[flexbackup-help] flexbackup problem

[larry c. <lar...@ut...>]

I have a quick question that I am sure that you will be able to answer
quickly.  

How do I exclude a sub-directory from being backed up.  We have a NAS
server that is mounted on our box that we back up.  We want everything
else backed up under the main directory that this sub-directory is
under. The sub-directory is a samba mount.  But every time flex runs a
back up, it also tries to back up the NAS server and it freezes the
system.

Ummm... see the "prune" section in the config file comments.

 $prune{'backupdir'} = "subdir";

 flexbackup -dir /home


or, you could put in the config file
  $set{'mybackup'} = "/home";

then run
  flexbackup -set mybackup

[flexbackup-help] flex pre-setup ? about dir exclu.

[Stephen R. <sr...@pr...>]

I would like to backup only the /home directory, so do I need to prune
all of the other directories in the root with prune in the conf file, or
is there a way to tell flex not to backup every by default.

Thanks

cpio with "-0" just means to use null separation for the filename list
rather than newline separation.

Current FreeBSD cpio seems to support -0, I just checked.


You could use type "rsync", if you have rsync 2.5.6.

I could modify flexbackup to use pax for the "copy" type, it is supposed to
be command line portable *everywhere*.  Do you have pax on OS X?

If not I may switch that "copy" back to newline-separated cpio's, thats a
trivial change.

[flexbackup-help] flexbackup on Mac OS X

[Peter W. <pe...@pr...>]

Greetings,

I am attempting to set up flexbackup on my Mac OS X 10.2.8 system, 
using the 'copy' method to simply copy all backup files to another hard 
drive. The cpio command seems to fail as follows:

--------
| cd "/Users" && find . -depth -xdev ! -type s -print0 | cpio -o -0 -H 
newc
|   -v -C 10240 | (mkdir -p /Volumes/Backup/Users.0.200310120841 ; cd
|   /Volumes/Backup/Users.0.200310120841 ; cpio -i -m -d -C 10240)
|------------------------------------------------------------
cpio: illegal option -- 0
usage: cpio -o [-aABcLvVzZ] [-C bytes] [-H format] [-O archive]
                [-F archive] < name-list [> archive]
        cpio -i [-bBcdfmnrsStuvVzZ6] [-C bytes] [-E file] [-H format]
                [-I archive] [-F archive] [pattern...] [< archive]
        cpio -p [-adlLmuvV] destination-directory < name-list

ATTENTION! cpio archive volume change required.
---------

Just wondering what the "-0" option is trying to accomplish and what I 
might be able to substitute so that it works with my version of cpio. I 
don't know for sure what version of cpio I have, but according to the 
manpage, it is from BSD, February 1997, by Keith Mueller at UCSD. That 
would make sense since Mac OS X is based on FreeBSD.

Thanks,

Peter

[flexbackup-help] flexbackup-1.2.1

[Edwin H. <ed...@co...>]

Several things had accumulated since 1.2.0 in July.
Some minor fixes, some minor additions.  

Available at http://www.flexbackup.org

Changes:
 - Added "-ignore-errors" flag to allow backups to continue even if
   commands return non-zero exit status.  Use at your own risk.
 - Added contributed manpages
 - Add 'rsync' type that acts like 'copy' but using rsync instead of piped
   cpio's.  You need rsync >= 2.5.6 for this to work!
 - Added lzop compression support
 - Spinning bar indicator for long-running pkg delta operations if
   output is a terminal
 - Recognize .deb files as ar archives
 - Skip proc/devpts/devfs/tmpfs for traverse_fs=local or all
 - Add hooks for mbuffer's multivolume support (experimental)
                                                                                      
Bug fixes/cleanup:
 - FreeBSD pkgdelta support fixed up
 - Cleanup better if error detected
 - Fix quoting in check_remote_progs if your remote shell is csh
 - Make sure we don't generate conflicting index keys (as long as -newtape
   is not run in parallel)
 - Cleanup a bit regarding block devices
