I would like to build a file server for backups. The server needs to be available 24/7 in a mixed Windows/Linux network, but service should not exceed 1 hour per day. Thats why power consumption is my main priority.
What do you think is the best hardware to build it? What about software ? do you suggest a Linux distribution ?
Edit1: The server should take 1 to 4 terabyte drives, I'm not aiming at speed, redundancy is not a must, but will be appreciated if not very costly. My budget is kind of limited.
Edit2: If I can get a router or a wireless access point to do this job (using USB ports, and probably a modified firmware), then it would be a great idea. Any suggestion ?
