I installed my old Dell P3 mainboard in the backup server. Its a bit more responsive now. I’m copying over all the files on the backup array, so I can move to Linux software RAID. A bunch of dumb ATA PCI controllers and software RAID should be fast enough for the backup server. I don’t want to buy another 3Ware card right now. Now I just need to find 3 x 160GB or 3 x 200GB cheap so I can move my 120GB disks into the backup server.
Next, I’m going to build a new firewall box.
