Ubuntu – Why does Déjà Dup say there is no space left

backupdeja-dupdisk-usage

I'm trying to backup my home directory (excluding a few folders). The backup is saved on a ~300 GB partition (called backups) of an internal drive, but not the same drive as the home directory. When I try to backup, everything goes OK until at some point Déjà Dup says there is no space left on "backups". The problem is that Déjà Dup only used ~20 GB at this point, so there is a ton of space left. I tried several times without luck.

Why is Déjà Dup saying this?

The size of my home directory, without the excluded folders, is 136 GB.

So there are three possible places where Deja Dup might be out of space, and I don't think its error message tells you which. There is a bug filed about that.

You may have run out of space on the target partition (which it sounds like you didn't)
You may have run out of space in your home directory (~/.cache/deja-dup can get large)
You may have run out of space in /tmp

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.
