In addition to modifying your strategy (since one backup set per month
probably won't provide the level of safety you want), you might want to look
at changing computers from a PII to a PIII. The matching process is very CPU
intensive and scales based on CPU performance.

The interesting thing about backup systems is that there are so many places
for potential performance issues: network, backup drive, OS, I/O, etc. It's
rare (and wonderful!) when you can change one component and have a huge
impact on backup performance.
