Comment 1 for bug 1970008

Hello, thanks for the report and sorry that Deja Dup is giving you trouble.

I agree that the cache folder can grow quite large. That's largely duplicity's (the underlying backup tool) doing, but it's possible we are contributing to the problem.

Does the problem get better if you delete the cache file and try again? (i.e. are we keeping extra stuff we don't need around, and maybe we can more aggressively prune the cache - or does duplicity really need to resync those files every time)
