Some explaining is perhaps necessary. Our BPC-project started because the 
*nix-users needed to backup some really large molecular modeling projects. 
These are easily in the 5+GB range each, and the users produce sometime five 
or so a day each. With four (current) users doing this we fill up storage 
fast. With this in mind and the time this was begun, storage was still pretty 
expensive. This means we only keep about 5-6 full backups, depending on how 
much storage is available. That's our historic data.

Hmmm... Apart from the raid5-problems I had some time ago, our SW raids have 
been functioning very nicely indeed (knock on wood...).

Darn those sloppy users... ;-) I try to restore files and folders from time to 
time, just to check things out.
