Memory check

My hobbit server (Fedora FC4) has 1.25 gig of memory installed. When the server is backed, up using Retrospect client, REAL memory usage spikes from 34% to 97% and stays at that level until a reboot. When I check the system performance, using the built in system monitor, user memory is at 18.9%. Dell Open Manage is using the most memory at 3% with a few additional processes between 1% and 2%. Everything else is well under 1%. What exactly is hobbit reporting on when it says that Physical/Real memory is at 97%, Actual memory is at 17%, and Swap is at 0%?

Thanks,
