Backup failing with No Space Left error

Follow these steps to free up as much space as possible while keeping the latest backup:

Delete old backups through duplicity

You could try deleting old backup files manually.

For deleting all but the last full backup, open a terminal and run this:

duplicity remove-all-but-n-full 1 file:///media/nate/Backup/ --force

Delete files from failed backup sessions

If there is still no backup space, this might help (it deletes files from failed backup sessions):

duplicity cleanup file:///media/nate/Backup/ --force

Still no space

But for your case, I suppose that the backup partition is just full.

• There is one full backup (from 2013-09-01), and
• many increments (until 2013-10-19).

This means, that Duplicity/Ubuntu Backup won't delete any files as that would destroy the latest backup.

So for now, you will need to find backup space somewhere else and run a new backup. Or, you delete the current backup by hand and run a new backup immediately afterwards. But keep in mind, that you won't have any backup until the new backup is finished successfully.
