Take whatever I say with a grain of salt, since this something still
in the process of being rolled out and tested. Hopefully it may help
with ideas, though. One basic theme is that since I'm not backing up
to tape or some other sequential-access device, I avoid having more
than one volume per disk file.
I have Bacula set up to back up everything to disk on the backup
server, using a pool for each level type (full/diff/incr). The pools
mainly function to auto-label the jobs and to set retention periods.
JobDefs set override pools for each backup level, and the Schedule
sets the preferred backup level in each Run= line.
Since I'm backing up to files, the volume names have a very direct
association with the filenames, so I want them to be pretty
descriptive. Example label format:
Label Format = "${Year}${Month:p/2/0/r}${Day:p/2/0/r}_FULL_$
{JobId}_${Client}"
The level "FULL" is hardcoded because the variable for job level is
sometimes set weirdly when you run the job manually from the console.
The JobID is in there so that each label is unique in order to
prevent the need for constant manual labeling when combined with
"Maximum Volume Jobs = 1".
Since I know from scheduling about how often each kind of backup will
be done, I can set retentions with that in mind. E.g. Monthly full
backups, I want at least two in the past, I can set retention to 2.5
or 3 months.
Finally, the storage daemon is set to split volumes into files which
will fit on CD-R's using the "Maximum File Size" directive, although
maybe it should be DVD-length. One thing I haven't tried, but would
be neat--if I could set volume names in such a way that they would
create a directory tree using the File device... I've just settled
for easy-to-parse filenames.
