Good advice. I recently had a head crash on the HD containing my home=20
directories. I had been using tar to archive on the other drive.=20
However, my tar archive became corrupted by including a VDI file where I =

lost some of my directories. I since sent the bad drive out for=20
recovery, and I now do a nightly rsync to the new 255GB USB drive I=20
received with my recovered home directory.

Advantage to a USB HD: You can keep it plugged in and have the backup=20
run automatically.
Disadvantage: A lightning strike can damage anything physically attached =

to your computer which is one reason you may want to unplug it.

I suspect that prices of Blue Ray will drop and that could be a viable=20
periodic backup.

Another alternative is to use an online backup service. We've discussed=20
them here before.
