Re: [Bacula-users] Mixing incremental full volume pools (disk based) during restore

Today I tried a restore job using both incr. and full volumes, and when bacula (5.2.6 on centos 6) needed to access the incremental volumes, it tried to open them in the full filestorage directory as opposed to the incremental filestorage directory. I worked around the situation by creating symlinks in the full filestorage directory pointing to the incremental backup volume files and bacula readily accepted those links and read the incremental stuff off the volumes. I wonder if this is the expected behaviour, or would it be better to keep both pools in a single directory (if that's even possible)? Should I have modified the Storage resource before starting the restore job (alhough the restore job needed both full and incremental volumes)? All the best thanks in advance, Uwe I had this issue in the past as well. The solution was to change what type of media. Here is an example out of my SD configuration file. Device = Differential Media Type = File-Diff I had to update my pools to reflect the new media type and backups and restores work with out having to use the symlinks. -- Craig Van Tassle HUBzero.org System Administrator YONG 1006 Desk Phone : (765)496-6413 -- This SF email is sponsosred by: Try Windows Azure free for 90 days Click Here http://p.sf.net/sfu/sfd2d-msazure ___ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users

Hi Phil,
the reasons are mostly historical: I started doing incrementals to
disk with fulls to tape, so I had a separate incremental disk pool and
then simply added a 2nd disk pool for the full backups. This way, I
can also later separate the pools to different disk devices
I can also live with symlinks as I have a limited number of
incr. volumes, but it sure would be nicer to have bacula select the
correct pool automatically.
I changed the media type in the sd config and the Storage definition
in bacula-dir.conf like so:
Device {
Name = FileStorage_incremental
Media Type = File-Diff
Archive Device = /mnt/disk/online_backup_incremental
LabelMedia = yes;
Random Access = Yes;
AutomaticMount = yes;
RemovableMedia = no;
AlwaysOpen = no;
}
Storage {
Name = FileStorage_incremental
Address = bacula-server
SDPort = 9103
Password = X
Device = FileStorage_incremental
Media Type = File-Diff
Maximum Concurrent Jobs = 4
}
and restarted bacula. I then updated pool from resource for the
incr. pool and all volumes in pool, but the media type is still
listed as File when I select list media in bconsole. Do I need to
update the media table in mysql? Would it be simpler to merge both
pools into a single one?
All the best, Uwe

I don't think you should need to do either of those. I have a total of
five pools - Full-Disk, Diff-Disk, Incr-Disk, and Full-Tape, plus a
scratch pool - but all of my disk volumes are in the same /spool/bacula
directory regardless of the four possible disk pools they belong to.
For me, this Just Works. I have never had Bacula fail to find a volume
as you've described. Bacula knows which volumes belong in which pools,
so I don't see a need to keep them separate.
Of course, you're doing a number of things differently than I am,
starting with having a separate Device for Full, Differential and
Incremental. Still, I would just try putting all the volumes in the
same directory and adjusting the Archive Device settings accordingly.
There's really no difference between the different File storage devices;
if you don't try to separate them, you could even end up with more
flexibility because you can just let any Job use whichever device is
available to mount the volumes it needs.
