While struggling to get my feet back on the ground with another issue, I played with selectively deleting backup versions until I reach a working state again.
I ran a DELETE command with --dry-run and versions --version=0, 1, 2, 3, 4, 5. Comparing the version numbers I get in the “Restore” dialog to the ones listed in the command’s result (in the GUI) I found that they seem to be off by one, e.g.: in Restore, version 0 has a time-stamp of Jun 29, 11:29, version 1 is from June 29, 11:16
whereas version 0 in the command’s result has the time stamp of 11:16, which corresponds to the one of version 0 in restore.
FWIW, both backup versions are probably incomplete (because they failed to complete) - the one from 11:16 is labeled “partial” in restore - but I don’t think it should matter for this question.
What am I missing to understand this mismatch?
