Hello, I did that at a customer's : One single drive LTO autoloader in which I have the primary backup pool and also the db backups and one single external DLT1 drive for offsite copies. Each day, I backup the primary pool to the DLT1. The main problem is that I had to write scripts in order to have the right tape in readwrite state and the other ones in offsite state . I found it a little tricky because it seems that TSM isn't able to check which tape is in the drive before choosing on which it will write. But as Nick wrote, the reclamation is not a real problem as if your tapes are in offsite state, TSM will use the primary tapes for reclamation.. Another possibility which have already been described in this list is to buy cheap big disks for the primary storagepools and to use the autoloader for the copypools only. But this may be expensive if you have big amounts of data to backup.

When TSM reclaims offsite tapes, it uses the onsite copy of the data, not
the offsite tape (if the copypool tape is offsite), so your hardware is
adequate to do this, since you can already do the backup stgpool function.

Hi all,
Can TSM use a small autoloader to do the onsite copies and a
manual tape drive to do the offsite copies. The offsite copies couldn't
be reclamed, but they could be destroyed when they have very little data
left on them. Next time an offsite copy is done, the deleted files would
be re-transfered to the offsite copy.
Since you still can't reclaim offsite tapes to a reclaimpool, this could
be done on a small install so that you don't need a two drive library to
use TSM to backup your data?
What do you guys think?
