Tom,
Yes, that's exactly how it works. Just make sure you list enough volumes
to always have one of them in your library, plus maybe a buffer. I had a 7
day retention on my database backups, plus one day transit back from the
vault, so I used 10 volumes, and never had an issue.

Please respond to

I'm about to have mixed media (lto1 and lto2) in the same library. All
the drives will be lto2. I intend to set the lto2 media as scratch and
define the lto1 media to specific storage pools. Our current D/R hotsite
contract is for lto1 drives, so I'm planning on using the lto1 media for
all my copy pools.
Having said that - I need to make sure my database backups go to lto1
media. I've never used the 'volumes' parm on the backup database command
before. If I issue the command "backup database devclass=lto type=full
volumes=v1,v2,v3,v4" will tsm use the first available volume in the
list, or will it ignore the command if v1 is already an un-expired
database backup? In other words, how creative do I need to be in my
automated backup script?
