...what you need to do to tune your system to work effectively as a
backup server is extremely different from, say, tuning to a database
load, to tuning for a compute load, to tuning for anything else.
You have not even given enough information about what you intend to use
it for:
* what parts of performance are you concerned about?
* what is the backup software?
* how does it get data from the clients?
* where does it spool that data temporarily?
* where does it store it finally?
* what compression, format transformation, etc happens to the data?
* what filesystem are you planning to use, and is that fixed?
* can you use something other than RAID5?
* is it software RAID, hardware, or FakeRAID?
* What sort of dual CPU is it -- two sockets, two cores, or one HT CPU?
* how much memory do you have?
