Deja Dup keep failing to backup, giving the following error message:

Failed to read /tmp/duplicity-rrKaLL-tempdir/mktemp-Xw6o6E-1: (<type 'exceptions.IOError'>, IOError('Not a gzipped file',), <traceback object at 0x2172368>)

The problem remains after deleting ~/.cache/deja-dup and also after restarting.

Is this a known problem? Is there a way to force the backup, other than deleting also the remote repository and starting the backup from scratch?

forcing the backup may corrupt the data, I wouldn't.....Better to find the problem or use another means of backups –  Ringtail Mar 4 '12 at 18:16

That would be the best idea. You could also make a new folder and name it "Backup 2", then go to System Preferences > Backup > Location and change it. If it works, delete the old one and rename this to "Backup", but make sure you update the settings.
