Thanks to you guys (and ladies) I solved first half of my problem.
I set up second instance of TSM on my test server, and backup sets on virtual 
volumes work just fine.

Second half of the problem is: 
How can I extract these backup sets from virtual volume.
All my customers are remote, and the backup is done over the WAN. My plan was
that in case of disaster I copy backup set to my laptop and go over there
and help them to restore locally from backup set.
If this is not possible the only other way that I can see it, is to restore
actual files on my laptop and then go over there and just copy the files
from my laptop. But I don't like this because I have to ask my customer for
password and encryption key.

And last question is how you expire backup sets on virtual volumes.

Thank you,

Subject: Backup set - Instant archive

Hi All,

We would like to start using instant archive (backup set).

Average archive per customer is around 10GB.
We have LTO2 tapes (200/400), and it looks like that every new backup set
must be created on new tape. I can fit around 20 archives on one tape; if
it's possible.

Does anyone know if this scenario is possible. Manual is not really clear
about this.
