You could simply do backuping to some folder, unique for the current host.
An example from one of my script:

/usr/bin/flexbackup -set all -differential -device 
/mnt/backups/`hostname`/flexbackup >/var/log/flexbackup_diff.log 2>&1

[flexbackup-help] Include hostnames on local backups?

[Phil R. <phi...@ti...>]

Is it possible for flexbackup to include the hostname in the filename  
when backing up a local filesystem? I run flexbackup on two different  
machines and have to do some renaming before copying content over to  
the first machine from the second.

[flexbackup-help] Exit codes

[Phil R. <phi...@ti...>]

I am looking to add additional automated processing after backups, but  
need to clarify the exit codes used by flexbackup.

What exit codes does it use in the following circumstances:

Wrong wday (looks like 0 to me)

Normal completion

Others?

Of course, it is simply a shell script, but if this is known, it would  
save me having to work my way through it.

Hi Niall: /home/robert is 187.9 MB, so that's most of 208 MiB :-) And I
haven't attempted any larger backups on this PC. No large videos either;
my largest file is 14227366 bytes:
~/.gnome2/epiphany/mozilla/epiphany/Cache/_CACHE_003_

However it does seem to be the .gvfs 'find' error that is causing
flexbackup to delete my archive. I created new user 'fred' as a test:

Logged in as fred once - logged out - /home/fred was using 28KB. At this
point flexbackup hit the same .gvfs find error, and the archive was
deleted:

robert@venus:~$ sudo flexbackup -set homefred
  ...
find: ./.gvfs: Permission denied
level 0 /home/fred Tue Mar 24 21:59:12 2009 tar+gzip from venus
  ...
ERROR: non-zero exit from:
find . -depth -xdev ! -type s ! -regex .*/[Cc]ache/.* ! -regex .*~$
-print0

ERROR: exiting
  ...

Logged in as fred again - ran 'fusermount -u .gvfs' - logged out -
logged in as robert again - ran 'sudo flexbackup -set homefred'. This
time there were no errors in the log and the archive was left on the
output device.

Looking at the code, flexbackup seems to wait until find, tar, etc. have
all completed, then check for errors afterwards. If it notices an error,
then the code tries to delete the output file(s).

None of this explains why flexbackup actually deletes the archive on my
system, but not on yours. The code does mention an ignore-errors option;
presumably you're not using that?

I expect you've got more up-to-date versions of findutils, gvfs-fuse
etc. than I have. If so, presumably you are benefitting from some fix or
other that hasn't percolated through to gNewSense yet. (I have findutils
version 4.2.32-1ubuntu2, and libc6 version 2.7-10ubuntu3.)

All the best, Robert

Re: [flexbackup-help] flexbackup error

[Niall B. <ni...@la...>]

Hi Robert,

Is it possible that the .gvfs is the last entry logged that isn't a problem,
and that the problem is elsewhere and failing? The error message is from
find,
but the failure is from tar.
How about creating another user account on the machine, and running a
comparison backup for that home directory?
How much diskspace is your home directory using? Is 208MB a large percentage
of it?
Have you any unusual files (such as large video) in your home directory?
Have you any other backups on the system that complete that are larger?

You could also try switching to an rsync archive type for a few runs,
 and see if the problem is expressed differently.

Good luck with it. I'm very interested because if there's a .gvfs issue
around that can be triggered easily, it could affect a lot of us.

Yes, that was the solution. According to 'mount', gnome-fuse-daemon was
mounted on my .gvfs. I needed to unmount it before the backup.

First I reverted to my original flexbackup.conf (the one without any
".gvfs" prune/exclude expressions). Then I used

$ fusermount -u ~/.gvfs

to unmount the daemon from .gvfs. Then

$ sudo flexbackup -set home

backed up /home without errors. 'find' simply treated .gvfs as an empty
directory :-)

Q. I didn't create .gvfs ... Where did it come from and who mounted this
daemon on it?
A. As far as I can tell (1) GNOME automatically creates ~/.gvfs (2) it
is designed as a mount point for gnome-fuse-daemon (3) GNOME
automatically mounts it. (gnome-fuse-daemon is in the gvfs-fuse
package.)

Q. What happens if you unmount this? Is it safe?
A. It seems fairly safe. It certainly seems sensible to unmount it
before root tries to back up your home directory.  GNOME re-mounts it
automatically next time you log in.

Package versions: gvfs-fuse 0.2.3-0ubuntu4, gvfs 0.2.3-0ubuntu4,
fuse-utils 2.7.2-1ubuntu2, gnome-about 1:2.22.1-0ubuntu6gnewsense1.

Many thanks Niall,
Robert

Many thanks Niall. I'm using flexbackup version 1.2.1-6, with .tar.gz
output format, writing to a 4.3GB drive in an external housing,
connected by USB. The external drive has ext3 file system and 2.7 GB
free space.

Re: [flexbackup-help] flexbackup error

[Niall B. <ni...@la...>]

Hi Robert,
I can confirm that I'm using a stock flexbackup 1.2.1-6 on ubuntu 8.10
without this issue.
I usually use a different product (backuppc actually) for nightly home
directories, so I thought I might just not have been hit by it. I use
flexbackup for mail spools and config directories as well as for snapshot
backups before doing any reconfiguration tasks...

I added a /home stanza to my flexbackup.conf and ran the job both with users
logged in
to GNOME (so ,gvfs was active), and late at night so that it wasn't.
I do get the same "find: `./.gvfs': Permission denied" entry in my log,
but it is not a showstopper. What backup format and medium are you choosing?
Would you mind posting your settings using something like:
*
egrep -v -e '(^#|^$)'  /etc/flexbackup.conf

*
Do you actually have a set defined as /home, or is it /home/robert ?
Your prune expressions are not being honoured according to your log.
You might find defining a set as /home/robert and adding

 $prune{'/home/robert'} = ".gvfs";

might be more effective.

You should probably put it into an exclude_expr as well as in:
*$exclude_expr[2] = '.*/.gvfs/.*';

*Good luck with it,
I'll be watching with interest.
I've been using flexbackup for years, and there's always a way out of these
hiccups!

Re: [flexbackup-help] flexbackup error

[Robert C. <rob...@ti...>]

In response to two threads from May-June 2008:
  Re: [flexbackup-help] flexbackup-help Digest, Vol 9, Issue 1
  Re: [flexbackup-help] flexbackup error
(Apologies for lack of reference headers -- I've just joined the list
and my email software hasn't seen the above threads.)

I'm experiencing a problem which sounds similar to Andrew Schein's. My
home directory contains a 'directory' called .gvfs, of zero bytes; when
I ask flexbackup to back up /home (sudo flexbackup -set home), it starts
creating a .tar.gz file, does about 100 MB, then stops and deletes
the .tar.gz file. And in the log there's a similar 'find' error:

=== START EXTRACT ==

 [ ! -e /tmp/flexbackup.11443.venus/exitstatus.11443 ]
------------------------------------------------------------
find: ./robert/.gvfs: Permission denied
=== END OF EXTRACT ===

I'm running gNewSense 2.1 "Deltah" (based on Ubuntu 8.04 LTS--"Hardy").

I keep trying to add a $prune line for /home, but perhaps my regexp
syntax could be improved:
  $prune{'/home'} = ".gvfs";
  $prune{'/home'} = "robert/.gvfs";
  $prune{'/home'} = "robert/\.gvfs";
  $prune{'/home'} = "\.*\\.gvfs";
None of these prevent 'find' from erroring on that file.

Can I "prune" my way out of this?
Any advice gratefully received :-)

Thank you very much,
Robert

You've successfully reminded me of what it was I needed to do.

It needs a key suitable for unattended interactive use in root's ssh  
with the public key authorized on the other machines - and it's the  
one thing I hadn't redone.

Many thanks all - I knew it would come to me if someone said the right thing.

The clue was also that, if I directly logged in as root, it prompted  
for the password!

As root - flexbackup is installed on one machine only and accesses  
three (four if you count one that is never done automatically) other  
machines by ssh.

I am.

Yes to all. flexbackup runs as root locally and uses ssh to get into  
all machines as root.

> Check the auth logs on the remote machine to see if there's any difference.

The auth logs indicate "failed password for root". However, if I ssh  
manually, I don't get prompted for one. The auth logs show "Accepted  
publickey for root" - just what I expect - and it works also when I  
run flexbackup manually.

The problem I face is, you cannot increase the verbosity of ssh as  
called by flexbackup - if I could do that I could see more about why  
it is failing.

[flexbackup-help] ssh failing when flexbackup runs from crontab

[Phil R. <phi...@ti...>]

I replaced this machine a few weeks ago with a totally new build.

I have tried to re-enable automated backups but they only work for the  
local machine. Trying to ssh into the other machines logs "Permission  
denied".

This does not happen if I run flexbackup from the command line.

How do I make this work? Finding out why it doesn't may help but I  
cannot see how to enable more output from ssh in flexbackup.

[flexbackup-help] At block 0 all the time?

[João S. <se...@pt...>]

Hello

I have an HP DAT 72 USB drive model C7438A.
I have followed the instructions provided by HP for configuring the tape 
drive and everything *seems* to be in place.
I say seems because flexbackup --test-tape-drive fails all the 
time.After some debugging and losing quite a couple of hours i was 
trying to write files by hand to the tape after which i would execute 
the command:
mt -f /dev/st0 tell
and the result is allways: At block 0.
No matter how many files I write or whatever I do the result i get is 
allways At block 0.
In the begginging in used to erase the tape but it took so many hours 
(2h or so) that now i just rewind it but nevertheless the result was the 
same.
Any ideas how to solve this and finnaly start making some backups?

Kind Regards,

you should be able to as long as triggers are all the same. Otherwise you
can always create a simple permanent alias for it.

[flexbackup-help] Using p7zip

[Phil R. <phi...@ti...>]

There is a p7zip wrapper on my system. This can be used as a  
substitute for bzip2 with tar.

Assuming I make sure it is on all of my systems, can I specify it as a  
compress program for flexbackup to use with tar?

Hi guys! I'm also using flexbackup on multiple servers! Is seems very 
fine, especially I like differential backups.
But I not use bzip compression, just a simple tar.
$type = 'tar';

There are no issues with it.

Also you could try to switch to tar type of backups, and then do a gzip 
by other script.
Some example of script backuping my sql databases:

          echo "Compressing backups..."
           for i in `ls ${backupsdir}/*.sql`; do
                cd ${backupsdir} && nice -n 19 tar -czv --remove-files 
-f ${i}.tar.gz `basename ${i}`
           done

  # cleaning up old data
  find $backupsdir  -name "$host*"  -a -mtime +$savedays -delete


Also keep in mind that if you have a very lage tar backup bzip will 
compress it a very long type too.
So I don't use compression for this reasons. I just need fast and simple 
backups.

[flexbackup-help] Size limits?

[Birgit K. <bir...@un...>]

Hello,

I am trying to backup a 22GB directory over SSH and am wondering what 
causes flexbackup to choke on this.

This is the error message I keep getting:

afio: 22496m+181k+0 bytes written in 2068 seconds. The operation was 
successful.

ERROR: non-zero exit from:
cat

I'm running this from machine 1, and the backup goes to an external hdd 
linked to machine 1 via external usb.

Machine 1 runs the latest version of Ubuntu, with all packages in their 
latest official version.

Any ideas what might cause the error?

Thanks in advance,

Birgit

[flexbackup-help] configure /serve/backups/miscYYYYMM as backup catalog

[Aleksander B. <zu...@zu...>]

Hi All!

How do I organize my backups in this way (from config file): $device = 
'/serve/backups/miscYYYYMM'; (ofcourse I want to substitute YYYYMM with 
actual system date values)

Right now ilt looks like $device = '/serve/backups/misc';


Thanks

Re: [flexbackup-help] flexbackup-help Digest, Vol 9, Issue 1

[Andrew I. S. <an...@an...>]

It looks like some people at ubuntu are aware of the diffculties:

https://bugs.launchpad.net/ubuntu/+source/gvfs/+bug/227724

However, if flexbackup provided an option to bypass attemping to find,
stat, or tar .gvfs that would be really helpful in the short term.

I have found this problem affects other backup programs as well.

Cheers,

Andy

Ubuntu's ls has no such "O" option. Typically in linux I see special
file permission settings including sticky bit using "ls -l".
