I think what you are saying is that mmbackup is only keeping two
versions of the file in the backup, the current version and a single
previous version. Normally in TSM you can control how many previous
versions of the file that you can keep, for both active and inactive
(aka deleted). You can also define how long these version are kept for.

It sounds like you are saying that mmbackup is ignoring the policy that
you have set for this in TSM (q copy) and doing it's own thing?

JAB.
