NAS: what to do when your hardware breaks?

I have bought a Zyxel NSA-220 NAS case last year to have a secure backup of my pictures, videos and MP3s. I have set up two 500 GB SATA drives in RAID1 mode (mirror).

Now, this works all very well. If one of the disks breaks down, there’s always the other one.

But there are still things that worry me:

  • If I really have to replace a drive, will any drive with equal capacity work? What if there are no drives with equal capacity on the market?
  • What if the NAS hardware itself breaks down – will I be able to just attach the drives to a PC and rescue the contents (I guess they’re Linux EXT3 formatted)?

Backups are still a difficult thing to plan. What do you think – is a NAS system the way to go, or is it easier to just put the drives into a PC (which would have a higher power consumption)? Any ides appreciated. What do you do?

  1. I’ve gone with a big disk in my home computer (1TB, about to be joined by another 1TB non-mirrored drive), and then a USB disk for syncing with, which is then kept at work. If the worst happens, and the computer was damaged/stolen, I can simply take the external USB drive and plug it back into the new system.

    Having a mirrored backup system is all well and good, but if it’s in the same location as the original, then it loses some of it’s value.
