In the past I have shied away from using custom backup software: I have just copied the files in full to a different drive, because then I don't need special software to recover them (e.g. if my computer was stolen or destroyed, would a different computer have the correct recovery software?). So, if I use the built-in backup application in Windows 7, and I loose the computer, can I recover those files on a different computer? Does it need Win7? Will somebody else's copy of Win7 do it?
