Never had that problem, we are on 6.1.3 on windoze. Our savesets are usually in
The 50 - 150 Gb range

We are using staging, but it only works with small saveset, less than 2GB. When a saveset is greater than 2GB, it won't get staged to tape. Our 6.1.1 NetWorker server is on Solaris 8. Do you have this kind of problem?

Yes staging does all the cleanup that you need, but the information will be on disk for a minimum of one day/24 hours (function of the software) before it will be staged.

You can overide that manually by staging the disk volume whenever you feel like it, but that defeats the purpose of doing it automatically.

I don't use rman, I shutdown the databases, clone the filesystem, bring up the databases and send the clones to backup (disk). My databases are then left on disk for 2 days before they are staged, and I have room for 3 days worth of databases, incase I have problems with the autochangers and their ability to keep up.

Depending on what you backup for your entire enterprise, staging keeps our tape drives running 24 hours a day.
