Should have stated that earlier. So 3 160 gig drives in a RAID5 would only give 320 Gig (approximately). So I would prefer to use four drives and get the maximum available space. Backups, well, for the most part this machine acted as my online backup for my other systems. I had just recently added some other software that now that the machine is down is causing me some grief, but no amount of backup would really help, except for some type of system image, because it was a service it was running, not a "data" issue. Thanks for all the replies! James
