It's strange that edgy version is reported to work fine. I had exactly the same problem yesterday (backup failed due to a flacky usb connection), and the only solution was to remove the directory with faulty backup.
I can confirm the problem still exists in edgy, then. -- Empty past backup directory causes simple-backup to fail silently https://launchpad.net/bugs/78349 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
