If you have NetBackup Database backups scheduled to run after each session
of scheduled backups,
1. Is NetBackup smart enough to queue the NB DB backup between other backups
that are scheduled?
2. If the NetBackup DB backup tries to run while another backup is running,
does the NB DB backup wait in queue or does it fail, or does it run and if
it runs does this mean that it is an invalid backup?
I have typically scheduled the NetBackup database backups from cron and used
the command line options to backup the database at a time that I know other
backups are not running. I just want to know what happens when other
backups are running or get queued to run how NetBackup handles those
situations. Especially how NetBackup handles the "after each session of
scheduled backups". The other thought here is that if we have multiplexing
and multiple schedules, we could have 4 different backups running and each
ending at a different time with no period of inactivity between start and
finish of the four backups.
So far as Media servers. If you keep all of the volume database information
on the master server, what does the media server provide that needs to be
backed up? I thought that the only thing that should be configured on the
Media servers should be the storage unit, and then have all classes, backup
policies, media pools, etc. configured on the master. What am I missing if
one of the media servers doesn't get a NetBackup db backup?
Thanks,
Dan

When nothing is running and the Catalog automatically gets backed up, it is
in a consistent state. If backups are running I would not count on it being
a perfect copy. That's just my feeling, in practice it might meet your
needs.
What I would suggest is just rotating the tapes used for catalog backups.
Let one run, give the last tape used to "someone" (heh) and assign a new
tape to the catalog config.
By the way, there is a bug in the catalog config gui which drops the media
servers from the config for catalog paths (don't forget their media info!)
in some cases under 3.4 (at patch 645 I think). I bet it may have to do
with spaces in the path name (C:\Program Files\Veritas\Volmgr\Database and
C:\Program Files\Veritas\Netbackup\Db\Media). I would avoid putting any
Netbackup installs in to something like "c:\Program Files\Veritas\Netbackup"
instead I would use c:\Veritas. There was a restore gui failure due to a
space in the path a while ago in 3.4. There are a bunch of path related
notes in this tech article http://seer.support.veritas.com/docs/234923.htm I
think MS Logo Certification requires the current default path.
If all that someone needs is a copy of the /db/images directory (for your
purposes) it would be simpler to just back this up in a regular class, so
the person could then import the tape to another existing system without
having to do a dbrecover.

I periodically have a need to backup our Netbackup DB to a tape to give
someone. If I use the "Immediately Backup DB," I know that no more backup
requests will be handled while the database is backing up...but what about
those backups that are already running?
Assuming I don't care if their backup information is in the database (say,
they're for completely unrelated classes/clients/pools/volumes), is it OK to
run a database backup
while there are active backup jobs?
I don't want to experiment ;)
