I'm looking to build a file and backup server. I want something low powered and cheap. Any recommendations for hardware?
Software wise: I plan on running Ubuntu on it. I want it automatically to rsync over SSH with my off-site server for nightly backups. I also want to use it as NAS for my computer here at home. I then intend to use rsnapshot so I always have incremental backups of my data drive.
I've done this before with a linux box, but the computer I was using was a dual xeon server and was costing too much in electricity to run. (It puts out a ton of heat). I'm wanting to setup something similar but that uses less power.
