I had a few postings detailing how I lost data/work through hardware failure. The kicker here is that I had done about three weeks work of sorting and renaming music files and placing them in the hierarchy I had decided on. I temporarily took the server down as I redid the network and mounted the big gigabit switch and tidied up stuff. It was after I got the LAN running at high speed that I was going to make the next backup of the library. Wouldnt ya know, the drive containing ONLY the library crashed. I did not lose any files per se, but I lost the work of the organization I had done, which amounted to about 50-70gig of files.

Now I back up every time I make changes, and to multiple drives. And I can do so remotely now if I need to.
