Since I've introduced FreeBSD snapshots into my Bacula plan, I've
started getting random backup failures. A server will fail one day, and
back up just fine the next. A server will back up fine one day and fail
the next. ...all with no changes to the Bacula configuration.
Below, I've posted pertinent portions of configuration files and message
logs. Please let me know if I need to supply any further information to
help troubleshoot this down.
bacula-dir.conf pertinent portions only...sensitive information removed
with: <*REMOVED*>
JobDefs {
Name = "BSD"
Type = Backup
FileSet = "defaultBSD"
Storage = storage01
Messages = Standard
Pool = Default
ClientRunBeforeJob = "/usr/local/bin/sudo /usr/local/sbin/snapshot
make -g1 /var:autogen_bkup"
ClientRunBeforeJob = "/usr/local/bin/sudo /usr/local/sbin/snapshot
make -g1 /usr:autogen_bkup"
ClientRunBeforeJob = "/usr/local/bin/sudo /usr/local/sbin/snapshot
mount /var:autogen_bkup /mnt/var"
ClientRunBeforeJob = "/usr/local/bin/sudo /usr/local/sbin/snapshot
mount /usr:autogen_bkup /mnt/usr"
ClientRunAfterJob = "/usr/local/bin/sudo /usr/local/sbin/snapshot
umount /mnt/var"
ClientRunAfterJob = "/usr/local/bin/sudo /usr/local/sbin/snapshot
umount /mnt/usr"
Priority = 10
}
Typical job, as they are all nearly identical:
Job {
Name = "app06_BSD"
Client = "app06-fd"
Schedule = "MonCycle"
JobDefs = "BSD"
Write Bootstrap = "/var/db/bacula/app06.bsr"
}
Typical client, as they are all nearly identical:
Client {
Name = app06-fd
Address = app06
FDPort = 9102
Catalog = MyCatalog
Password = "<*REMOVED*>" # password for FileDaemon
File Retention = 30 days # 30 days
Job Retention = 6 months # six months
AutoPrune = yes # Prune expired
Jobs/Files
}
My primary FileSet resource:
FileSet {
Name = "defaultBSD"
Include {
Options {
signature = MD5
compression = GZIP
}
File = /
File = /mnt/usr
File = /mnt/var
}
Exclude {
File = /proc
File = /tmp
File = /.journal
File = /.fsck
}
}
Finally, I get the same message from my /var/log/messages file at every
failure. The lines before and after this have nothing to do with the
backup.
