Czuch: I have not heard of it, i use http://www.adrive.com/ to keep copies of a lot of my stuff. Its handy if i happen to be somewhere and find out i could use a file or something

Of course there is another way (depending how knowledgeable you are). Install a slave drive inside your pc, copy all your files to there or an external hard drive.

I do not save anything on my Main C: drive
