I don't think that MEDIA_UNMOUNT_DELAY works with NBU 6.0 MP2.  Besides,
I don't think the MEDIA_UNMOUNT_DELAY would work for me.  The backup
occurs every hour, and if the tape needs changed, I don't want the full
tape to sit for an hour before it's finaly ejected and a new tape put
in, especially if more data has to spill over to a 2nd tape.

we used to use this in 3.4 and 4.5, it may still work in 5.x or 6.0. put
it in bp.conf. i think the delay number is in seconds, we only needed
the tape to stay in a short while as the next oracle stream would start
within a minute.

 

# stop tape from immediately unmounting for oracle backup/restores:

MEDIA_UNMOUNT_DELAY = 60

 

thanks,

jerald

All,

Is there a way to have netbackup keep the tape in drive of a robotic
library?  I'm doing hourly backups of the Oracle Archive Log, and the
tape gets unmounted and put back into it's slot after the backup is
completed.  Is there a way to tell netbackup to keep the tape in the
drive until the tape is full?  We did that with Legato, and now the we
have moved to netbackup we are concerned about the wear and tear on the
tape drive.  Since it's constantly mounting and unmounting the same
tape.
