The error occurs during the post-backup verify phase. Duplicati considers the backup to be good, but reports 3 errors. And it goes through all the retries, etc., so the error is persistent, not behaving like a network performance issue or anything transient, _especially_ considering that it just completed a “good” backup. (Backup was after Windows Update, so there was definitely backup activity.)

I.e., the “‘list’ at start of backup, and a bunch of ‘put’ (upload) operations” have already been performed as part of the backup, if I am understanding your suggestion correctly.
