visit <http://publib-b.boulder.ibm.com/Redbooks.nsf/RedbookAbstracts/sg244877.html?Open> There you can find a nice redbook named "Tivoli Storage Management Concepts" (SG24-4877-02). Read carefully all chapters from 1 to 8 (and some of the others might also be very helpful). For example, in Chapter 3 "Data storage policy" you can find detailed answer to your question.

I need to change the incremental policy of a certain domain. I have 7 versions of backups set on my current policy and are kept for 30 days. If I change that policy to 90 days, will all my 7 backups be retained or does the change only affect the new incrementals? Are my old backup versions bound to my old policy?
