PC crashed

I had a system crash with all of my things on it, I got my hands on a cd
with "OnTrack data recovery" software, and was able to recover 95% of my data/pics/music, it took almost 36 hrs to get it back, as the scan was more or less bit by bit of the disk.

Now I have multiple external drives that I make copies to, and a second internal disk that gets hooked up once a month, make an image of the system disk, boot the backup to verify it boots fine, then disconnect it and run off of hte original. This protects me from viruses /disk failures, and I can be back online in less than 2 minutes.
