Re: Can you use a manual tape drive for your copypool?
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.

Dist Stor Manager [EMAIL PROTECTED] .EDU 03/14/2003 04:34 PM Please respond to ADSM: Dist Stor Manager 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?

Re: Can you use a manual tape drive for your copypool?
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.

Re: Can you use a manual tape drive for your copypool?
It is possible but has its limitations. I even made TSM working with single drive (manual lib) for both primary and copypool. In such cases periodic selective (forced fulls) might be of some use.
