Deja Dup doesn't let you do that manually through the UI (though it will do it automatically if you run out of space or tell it to only keep backups for a certain amount of time).

But you can do it using duplicity ("duplicity remove-all-but-n-full 2" for example, to keep only 2 full chains - see man page for more options).

Or if you're feeling frisky, you can delete the oldest chain files yourself, by just looking at the filename dates. But that's not recommended, since you might accidentally delete volumes from newer chains if you're not careful.

Can you help with this problem?
