Hi,

Looks like this will not work. ITSM will not overwrite the last version
of its database back-up, so you need another tape.

For some reason, I would be a little more carefull with my database
back-up. If you lose your database and cannot restore it (maybe because
of overusing this database backup tape), you endup with a lot more
scratch tapes than you would like to.... 

Have you looked at defining a file device class using a network share on
a remote server as target, making your database back-ups on that? 

Regards,

Karel

I have a TSM server with LTO tape library and a DDS tape drive. I would
like to backup the database to the DDS tape without human intervention.
I imagine the tape stays loaded in the drive and every day TSM will
rewind and overwrite it with fresh DB backup. I know that this isn't
optimal is it possible? I works flawlessly to do the DB backup to the
library but I don't want to waste all LTO tape with just a couple of
gigs when the library is always almost full.

Thank you for any help.

Michal
