Raid 1 isn't so bad, as each side of the mirror is a perfect copy and you don't have to work out a stripe size. Still your need to set it up on a real linux box I expect. If you wish to read the stuff.

Write you data to another device it could be a disk on a different system, a tape or a CD,DVD, BluRay. With all backups you need to think, how often to do I need to do it... ie what can I afford to lose. What happens if my stuff is stolen or the house burns down... Personally I have a LTO-4 Tape library and give my father backups of all my systems at home!

Personally, as per my sig, I have a server with four 1TB drives internally, no RAID/redundancy at all - just standard Windows Home Server file system.
Then externally I have two 1TB drives plus another 1.5TB drive, which I pop into an external caddy once a month and then I use some backup software to copy the files across. It offers decent protection against hard drive crashes, because I should lose no more than 30 days' worth of data, which for me in a home capacity is acceptable.
Ideally I would have everything on disks as well, so I would keep a stack of blu-rays with all long-term data stored at my dad's, to protect against fire. Can't afford that though, so I just make do with what I have.
Tapes are probably the best of both worlds, since they're rewritable and easy to move from place to place, but the drives aren't exactly cheap.
I wasn't really pointing a finger at you, was just thinking that this thread is fairly intriguing - a lot of the time people want to build desktops with RAID 5 arrays and so on, because "then I won't have to do backups". Forgetting of course that RAID 5 protects against one thing - drive failure. File deletion, chipset failure, file corruption, fire/flood are all major risks, as you've seen here. Luckily, chipset failures are probably the easiest to fix out of all of those problems, but it's still a pain, and not cheap either if you have to source an exact replica of the motherboard/NAS you were using with the array.
Huzzah!
I got the old N2100 working, and it rebuilt the array just fine (took 6 hours mind!)
So crisis averted - it's rattled me though. I'll back up all the photos to another server and DVD (should only need 14 of them) Digital Video will be a bigger proble.
Answers on a postcard for secure backup suggestions...
