I'm glad David asked this question, because I have the same one, as I have been digging around in the backups table trying to figure out what goes on.
The question is, if retextra is 15 and retonly is 15, and you take one full NDMP backup followed by 20 diffs, does anything roll off? How many fulls and diffs do you have left in the DB? Does the retextra/retonly apply just to the fulls, or just to the diffs? Both? How?

That mean if you backup the Full Backup with Managment Class A then backup Incremental with MG Class B, TSM will then change the FULL backup to MG Class B.
