[Novalug] Hard Drive Data Recovery

[Angelo Bertolli]

No, I mean I just don't use that much space.  I can fill it up if I want 
to... but if I'm not going to, I'd like get some benefit from that fact 
with some data redundancy.

For example, recently there were some bad blocks that messed up the 
mysql db files.  But luckily, I dump the database nightly to a text 
file.  Even though it's on the same drive, the text file was perfectly 
fine, and I was able to recover all of the databases.
