[Bacula-users] Clarification on Migration....

[Del M. <de...@al...>]

I am setting up a Disk to Disk to Tape backup and need some help with a
concept or two.

Here's what I'm trying to do:

1) Backup of critical files to 'MyVolume' (/mnt/backup/MyVolume)
2) text dump of catalog to /var/bacula/catalog
3) Append /var/log/catalog to 'MyVolume'
4) Migration of complete 'MyVolume' to tape.

Notes:
It's a simple 2 week tape rotation -- 10 tapes, one per day, with each
tape being overwritten every other week... full backup every night..
I'm not concerned with a tape being over written out of sequence, I'd
rather have the backup than the history.

I've listed the important bits of the bacula-dir.conf (Bacula v2.02)
file below and have the following questions:

    1) Are the 'Maximum Concurrent Jobs = 1' + 'Priority' directives the
correct way to serialize the backup?  If not, any suggestions on how to
do it better?

    2)  I set 'Maximum Volume Jobs = 2' on the disk volume (backup +
catalog append)... does the tape volume need to match this?  In other
words, if I set 'MVJ=2' on the tape, will I get two migrated volumes
placed on a single tape or just the one?  Conversely, if I set 'MVJ=1'
on the tape, will I get one fully migrated volume or will the volume
(which should have 2 jobs in it) get spanned across two tapes?

My apologies if this is covered somewhere else, I've looked but not
found it.  Please feel free to redirect me.

Regards
Del Miller
