Backing up using Deja Dup to an external drive is failing, it used to work fine. Last backup was 43 days ago. When I attempt to backup, Deja Dup decides to do a full fresh backup not incremental. At some point it reports Backup failed. "Failed with an unknown error", and gives the call stack below. I've tried this 3 times but get the same result. I'm using Ubuntu 18.10.

Traceback (innermost last):

  • Is there enough room on the drive for an additional full backup? – Organic Marble Jan 27 at 21:44
  • Yes I am backing up 143GB and there is 484GB free. – Matt Swan Jan 27 at 22:16
  • Is the external drive a remote Google Drive? – tidelake Jun 12 at 22:59
