I’m becoming anal-retentive about [tag]backups[/tag] lately. Back in the day I really didn’t care about it. But I have seen so many drives going bad in the last few months, that I’m getting obsessive about securing my own data. Right now I do a bi-weekly [tag]backup[/tag] to my secondary drive located in the same machine.
This is sufficient (data is replicated on 2 physical drives), but I’m not really content with it. What if both drives fail at the same time? Hell, what if my computer blows up? I know this is an unlikely scenario, but it worries me.
I really want a fully redundant solution. Lately I have been thinking about setting up a [tag]backup server[/tag] for my house network. I happen to have few ports free on the router, so this could be an interesting project. So fat this is how I envision my data storage on the cheap:
- low end CPU, and enough ram to run OS
- low end graphics card, no sound card
- 1 small (20-30 GB) disk for the OS
- 2 large 400GB+ drives set up as [tag]RAID-1[/tag] array
- stable linux distro capable of doing software RAID
- samba so that windows boxen can map it
I could reuse one of my old junkers from the attic, or possibly buy a basic headless low end desktop for $200-300. The two large drives would obviously be the most expensive part of the solution. But I’m quite confident you could buy a drive that size for under $200 (I saw one that size on neweg for $135). With a little bargain hunting, and scavengering I think it would be possible to build this system for well under $500.
It could be a very interesting project, and it would sure make me sleep better. My biggest concern of course would be setting up the [tag]Software RAID[/tag]. I have never done this myself, and most of the RAID machines I worked with have it done at the hardware level. There are some really cheap [tag]RAID controllers[/tag] out there – question is, would the OS support them?
This warrants some further research. If and when I go through with this, I will post a complete step by step report on how I accomplished it.
