To clarify the situation: DB assigned is 90GB, DB used is 63GB, full database
backup lasts for +/- 3 hours; cartridge is ejected and vaulted to another
physical location by operations staff. But not so during weekends.

TSM Disks and tape storage reside physically side by side so a db backup to 
disk 
at the same physical location doesn't make really sense. 
The idea was simply to "virtually" vault the db backup cartridge by the means of
OS to remote disks via Gigabit ethernet.

And getting cheap copies of db backups is also a charming approach.
