Good point. I myself do not use auto-save, because I like to know precisely where I was when a save took place.
It took me a while to figure out auto-save does not override (or overwrite) anything you do. For example, if you're working on SongVersion7.cwp, it will remain undisturbed. A new copy called "Auto-save copy of Songversion7.cwp" will be created when auto-save kicks in. You can always revert back to what
you saved, but if you hadn't saved recently and there's a power failure or whatever, you'll be happy Sonar created a newer copy.
As to the OP, I'm sorry, but trusting a piece of metal spinning at 7200 or 10000 RPM that was delivered via a truck subjecting it to more Gs than you'd like, and using parts from the lowest bidder...well, you know the rest. Doing work on a computer without making backups is asking for trouble, and you can be guaranteed to receive it, sooner or later.
