Can I beackup data from one node to two different tapes

Sasho -

With just one tape drive and no disk storage, either, your TSM server
implementation is severely constrained.  (How do you even perform
reclamation?)

You seem to have no opportunity for the TSM server to produce a
secondary copy of the data, so the only approach would seem to have
the TSM client generate multiple copies.  That might be achieved by
the client performing a second backup using another management class
(which is very awkward) or by using Archive instead of Backup.  A
less satisfying approach would be for the client to perform a
Selective backup with long retentions in place, and live with the
concept of the most recent Active and Inactive files actually being
copies of the same thing.

I would encourage you to expand your TSM server implementation to
have multiple drives.  Your customer is providing the justification
for the expenditure.  :-)
