Extreme size of .cache folder

[Andrew Gree]

My home's .cache/deja-dup folder is over 50GB. My "/" ssd is 500GB, my backup drive is 6TB.

So it's using 10% of the hard drive for "caching" and ran out of space without completing the backup.

Is there any estimate of how much %% to dedicate to cache folder so that backup is possible?

In any case, anything above 10% seems ridiculous.

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)

Didn't help

I deleted the cache folder and re-run the backup, now it ran out of space in /tmp folder (about same 50GB), ended up with a "No free space" traceback. At least it deleted the data in /tmp and freed up space.
