I'm planning on setting up a backup server at my parents' house so that myself, my siblings, and my parents can all back up all of our computers to it (We live over a hundred miles apart, in the relatively un-widespread-natural-disaster-prone state of Wisconsin, so this should be a good level of off-site protection for everyone but my parents). The basics are that I want the server to support at least 8 SATA II or higher hard drives. That requirement has ruled out all of the old machines that I have laying about (besides my laptop and desktop, both of which I use daily, all I have are several old machines that were made right around when SATA came out)
In a nutshell, I want the server to be reliable and cheap, in that order.
Approximate Purchase Date: e.g.: Probably within a month Budget Range: I'd like to keep the base computer (ignoring the cost of the HDDs) below $300
System Usage from Most to Least Important: Backup server running crashplan
Are you buying a monitor: No Your Monitor Resolution: Not important. Will hook up a monitor for initial setup then probably remote in for 99% of the rest of it.
Preferred Website(s) for Parts: newegg preferred, other reputable sites would be considered, but not preferred. Location: Wisconsin (USA)
Parts Preferences: Slight preference towards Intel, but not as much for a low-end system like this
Overclocking: No - it's a backup server that'll be speed-limited by the broaband connections' speeds SLI or Crossfire: No
Additional Comments: Power-efficiency would be nice
My basic plan is to do a software RAID 5 on the server, with the OS install on a separate disk. Crashplan (free version) should be able to take care of all of the networking issues and file-level versioning and error detection/correction. The RAID 5 should allow for a level redundant storage beneath that.
Now, I'm typically used to building gaming rigs, so this is a bit of a change-up for me, and hence I'm coming to you to see what you all think of this.
A note on the rationale for each part: The motherboard needs to support 8 SATA ports, and I've had good experiences with other asrock mobos. 4GB of RAM is plenty, and the combo deal brings its price down to the point of most 2GB sticks. The CPU is the cheapest LGA1155 dual-core offered by newegg, and should be all of the performance I'd nee for this. The PSU might be a tad overkill, but I like choosing something that I can depend on here. The case was the cheapest that Newegg offered that had at least 8 SATA ports. The hard drives are relatively cheap for 2TB drives, and they are Samsung (which has not failed me yet), and they are the EcoGreen, which is suposedly more efficient.
Well I was thinking of using ZFS as the filesystem for this setup, and maybe eventually buying a set of external drives for use as offline storage. Not quite mirroring, but for a backup setup, it should handle just fine.
