Why would you want to do RAID for a backup machine? Assuming we are talking disks full of backups, you already have 2 copies of that data, so you are not in trouble if a drive fails, you just put up a new one and backup the original data again.
RAID is for systems that need to be always up, that dare not be taken down to replace a drive etc. That's not true of backup servers.

Partially true here too. I have a server with just over a terabyte of RAID1 on a 3ware, which serves files to the two LANs we have here. It also serves as a backup to my workstation, which has about 500GB of space on it - important stuff (profiles, music, movies) are rsynced over every night. TV data for the last week is kept on the server (so that if a hard drive dies I can still watch stuff), but I don't keep a permanent archive of my TV stuff.
