If you doing a search on the board with the word incremental, you'll find this kind of discussion has been done a number of times. Incrementals forever seems to be a fairly common strategy (it is what we use at my company). As for amount of data backed up, that depends on your backup strategy. I am the NT client admin here (among other things), so I don't know the commands to issue at the ADSM master console level, but the sched log on the clients will give the amount they back up.
