Backup 3: a danger to your data?
Damien reminded us all of the importance of backing up your data. It isn't something that should be taken lightly, unless of course you don't have anything worth saving (do you really need all 14 gigs of those Andrew Lloyd Webber mp3's?).
With that being said, it seems if you are in possession of data that is vital to you in some way you would be best not using Apple's Backup 3 (free to you .Mac users). A number of people are having a tough time restoring data with Backup, and that is kinda the sole reason for it to exist.
