All that said, it seems like AnyBackup is suddenly open to a much wider user base, so I would not be surprised if people begin discovering new bugs. If you're using AnyBackup and you run across bugs, please, let me know what they are! You can raise issues at http://code.google.com/p/anybackup and I'll do my best to address them in a timely fashion.
For anyone who is a new user and is confused about how AnyBackup works, please read the wiki. (Be especially careful when selecting a backup drive, it will delete any files on the backup drives which are not on your content drives!)
