The client sends the directory list to the server, then the server walks
though it comparing against the previous full.

Where did you find the '100' factor? I'd have guessed bigger - and I
think some versions of 64 bit perl have bugs that make it consume more
memory. It might work better to stay 32-bit on a 4 gig machine - or add
more RAM if you are 64-bit.

Sar takes snapshots at 10 minute intervals - you might easily miss
peaks. If you are running more than one backup concurrently it might
help to cut back.
