Turn off garbage collection when backing up (-G), there should be no
problem backing up and restoring a 4gig database file.. I just backed
up a 9gig database in 22 minutes, dual opteron 242's, 2gig ram, 7200rpm
SATA drives.. Restore shouldn't take too much longer unless there are a
ton of indexes to rebuild, and of course other factors..hd speed..
Processor usage..etc..
