When I went to check the remote site where the backups were stored, I found they hadn't been running for some time.
So I'm not sure whether in my case:
* The backups were already failing, but now the error is starting to be surfaced
* The backups are actually starting to work now, but the delta since the last backup is so large, that this triggers a failure
* There is a new bug that is unrelated to why my backups weren't working before.
At this point I'll probably try to just start over or use a different backup system-- clearly deja-dup / duplicity isn't performing the basic functionality for me and hasn't for some time.
This happened to me as well.
