Hello Avy,
Backup versions are bound to a given management class. The backup
copygroup for that management class dictates the retention of the data
based on the VEREXISTS, VERDELETED, RETEXTRA, and RETONLY settings.
So if you have these settings configured for 7-day retention, then the
deletion should take care of itself (provided that you run inventory
expiration on a regular basis).
For example, the following settings will allow you to keep up to 7 days
worth of backups (unlimited versions, but no version older than 7 days):
VEREXISTS=NOLIMIT
VERDELETED=NOLIMIT
RETEXTRA=7
RETONLY=7
Also note that TSM *always* keeps the latest backup version as long as the
file exists; this would be the "active" backup version. This is regardless
of the above settings, which apply only to "inactive" versions (versions
that are not active).
With all of the above in mind, the members of this list could provide much
better aid if you could provide more details of your scenario, and how it
might vary from the above rules.
Regards,
Andy

The only dumb question is the one that goes unasked.
The command line is your friend.
