Hello,
I try use bacula 5.0.3 on suse linux to backup lvm snapshots.
Basically, I create a lvm snapshot called /dev/vmguests/backup using the
RunScript directive. Unfortunately, this is a sym link to /dev/dm-6. I
cannot be sure it is always dm-6. I would like to follow the sym link
and backup /dev/dm-6 as raw device.
The hints I found while googling are are not working (like appending /.
to the File directive) or obscure (like using bash scripting to resolve
File names).
I cannot simply mount /dev/dm-6 to somewhere because the contents is a
partitioned raw device of a kvm instance.
Maybe it is possible resolve the link using a bash script in the file
directive but I have not found information about when the File directive
will be evaluated relative to RunScript.
Has anyone a working solution for lvm snapshots?
The Job currently looks very plainly like this:
FileSet {
Name = FsVMMyDms # Adjust to VM
Include {
Options {
compression = GZIP
signature = SHA1
sparse = yes
}
File = /dev/vmguests/backup
}
}
Job {
Name = JbBcVMMyDms # Adjust to VM
Enabled = yes
JobDefs = JdVMGuest
FileSet = FsVMMyDms # Adjust to VM
Schedule = ScMondays # Adjust to VM
RunScript {
RunsWhen = Before
Command = "/usr/local/tbin/mountbackup.sh vmguests mydms" # Adjust
to VM
}
RunScript {
RunsWhen = After
Command = "/usr/local/tbin/umountbackup.sh vmguests"
}
}
Thank you all,
Tobias
