Deja Dup and Duplicity cache folders have same files

Asked by Chris Langley on 2020-05-07

Apologies in advance but I am a beginner and unsure if this is the correct place to ask a question.

I am using Deja Dup 37.0 and Ubuntu MATE 18.04 My understanding is that deja-dup acts as a GUI front end for duplicity and have noticed that within my home folder in the .cache subfolder I have deja-dup and duplicity folders, and they both contain exactly the same files. 5 GB worth in each folder.

Is this normal to duplicate the cache files in two places, as it seems to be wasting space.

Thank you.

No, should be just deja dup’s files... did you ever run duplicity manually, not through Deja Dup?

No I have never run duplicity manually so cannot understand why I have folders for both, and both have the exact same files.

When deja-dup runs it backs up to my dedicated USB HD and doesn't indicate any sort of error or anything out of the ordinary. Out of interest I could try deleting the duplicity cache folder and see if there is any adverse effect, or if necessary delete the entire backup and start all over again, if that would make things clearer.

Have now deleted the duplicity folder, within .cache, and run a further backup and all seems to be fine. Have tested restoring a file from the backup and all ok. So no further issue. But no idea why the additional folder was created with duplicate contents but grateful for Michael terry's input.
