GREAT, a forum dedicated to NAS devices....just the right place to ask about data security:
I'm looking for a not too expensive NAS with RAID1 for home use. So far I have looked at Linksys NAS-200 and ZyXEL NSA-220 and a few others.
Using RAID 1 one disk can fail without data corruption. But....one thing seems to be missing in that concept: What if the NAS itself failes? I mean, any computer hardware can fail....especially these systems that will be in use longer than a normal computer. So, there is two options at that point:
[1] The NAS have destroyed the data and possibly the disks. Not much to do about it....
[2] The NAS have just stopped working, for example from internal power supply failure. This scenario is more common (imho).
Assuming I get a NAS and scenario [2] strikes me after 5 years:
Can I just get a new one, plug the disks in and start it up? Even if that model is discontinued at that point?
Can I put one of the disks in a normal computer? Which ones use a decently common file system? Assuming the file system can be handled by the computer: Can the disk be accessed normally as a single disk even if it was part of a RAID 1 configuraiton?
RAID will never eliminate the need of a copy at alternate location. Question is whether it will be any better than just a one-disk NAS.... |

| You could get another NAS to back up the orginal NAS- though that's an expensive proposition. But yeah as you mentioned you should have an offsite backup anyways. Something like Mozy which gives you 2 gigs of free online backup would really solidify your backup plan. The drawback with offsite backups is that they're slow (limited by your broadband upload speed, which is usually only around 1 Mbps). So main backup via NAS, and supplementary backup via an offsite service would be a great solution. |
