 Using Raid?

If you are using a Raid Array to avoid data loss in the event of a drive failure, read this blog:

As (blogger) Robin Harris explains, the errors that led to disk failure could be carried over. I'm sure there are folk out there that think their Raid setup is keeping their data 100% safe - this is not so, it is essential to also have an efficient backup system.

That's why I don't bother with anything beyond Raid 0 for speed. I just do daily backups to a NAS I have setup.

The best archival medium I know of is Taiyo Yuden dvd-r dvd's. It is a little more trouble but is not subject to the loss of sectors and has a very long proven life. Used by the library of Congress for instance as the best method of archiving. The second hard drive on my workstation is not in a raid but it does have a system backup on it periodically.
