Even unlimited copies/retention wouldn't guarantee this: if someone deleted a bunch of files on their client drive, then they will be expired during the next incremental backup. If the deleted files happen to comprise 95% of a tape, the voile! you now have a full volume with only 5% valid data.
The best way to deal with this is to be more aggressive with reclamation, i.e. set the storage pool's reclamation threshold to something like 60 or 75 rather than 90 or 95. But the trade-off is that you will be doing reclamation more frequently. Since reclamation uses TSM server resources (tape drives, CPU, etc.), you'll have to balance your reclamation needs with other TSM management requirements. In general, I would recommend reading the Admin Guide from cover to cover (if you haven't done so already) to familiarize yourself with how TSM works. In particular, you can read up on reclamation in the chapter on "Managing Storage Pools and Volumes".

Just create retention policies that retain unlimited copies with a nolimit retention. That way once a volume is full, it will stay full because nothing will expire. Not that I would recommend it, but it is possible. Thanks, Robert Rippy.

I have to create a policy that does not create the situation where you have a tape with only 5% of real data stored and 95% marked for reclamation. Thanks.
