OK, last question for today:

I am in the process of trying to write scripts for a home-grown bpvault
solution.  Can anyone tell me what the logical flow of events for vaulting
is?  So far I have:
 
duplicate backups, 
place duplicate backups in Offsite volume pool, 
set expire date on these backups to 27 days so that they expire before
rotating back into library
eject offsite media from library, 
print media list to accompany offsite tapes, 
place new tapes in library and 
move them to the active media for backups volume group.  

Any other suggestions?
