Subject: [Veritas-bu] Annoying "feature?"

Ok - so I've been working on this issue recently and I'm wondering if
I'm just missing something or not.  Whenever a file or Oracle backup
fails the tapes it used remain assigned and the images do not expire
until after their retention expires.  So if a 1TB backup runs 24 hours,
then fails on the last kilobyte (for whatever reason) I am out 4 or 5
tapes.  This is most annoying!  I can't restore this data, so why retain
the images?

1 - is there an easy way to reclaim these tapes.  I know I can simply
bpexpdate -m them but its possible to have other data on them (because
of multistreaming.)

PM> You can duplicate the images you want to keep to another tape and
reclaim the tape using bpexpdate.

2 - If I lookup the images on the tapes, can I expire only them and will
NBU then use that space?

PM> No. NetBackup appends to tapes. That is why by default NetBackup
does not mix different image retentions on the same tape.

3 - Can Netbackup do all of this automatically for me?

PM> It already does. NetBackup expires the images based on retention.

PM> It is not unusual to have spare tapes in the event that a tape or
backup fails.

I'm working on other solutions including using checkpoint restart for
file backups but in the mean time, I'm struggling with this.

TIA,

-Jonathan
