Five tries of a file with the same size and hash is a sign of retries on the upload, then eventual failure. Seemingly there is a bug that lets the dlist file for the partial backup go out, then you have a big mess.
Your earlier screenshot looked more normal. The backup put dblock and dindex files, and dlist at end.
Please look further as requested in the mentioned logs. Maybe the Live log will do, but --log-file added probably has a better chance of catching sufficient details. You can start with –log-file-log-level=Retry.
When the backup completes it shows the following error: Error Size might be another retries problem.
Here, though, we have two images with different file behavior. Both have a warning. Neither says what, therefore we’re in the (unfortunately) usual spot where user has to find details to get more explanation.
Could you also perhaps offer ideas on what might be different to cause different backup failure styles? Earlier there was talk of deletes, restores, recreates, mistakes, but a step-by-step was never detailed.
Regardless, we can try working either screenshot you like, with you finding details for the red warning.
