rsync without a "data pool"

You can rsync back over the same data, and only the changes will be 
brought over.  If you're looking for an incremental backup sort of a deal, 
use the --backup-dir option, which will save changed files over to a new 
directory, so you can reach back in history.
The ability to roll the filesystem back to a specific data, including not 
having things there that were added later, is a bit stickier, but there 
are professional packages to handle that.  ADSM(tradename has been changed 
to "TSM" now) is particularly sweet in that regard, and I hear the Veritas 
NetBackup is nice, too.
