The potential main hurt is an exhaustive search from 90% to 100%. Hard to say it did that part.
Job “Complete log” has “BytesDownloaded” and “FilesDownloaded” to compare to destination.
Yes, the goal is always to prevent these unusual (for most people) problems. By the way, your
other posted Warning and Error messages are quite rare too. Try a web search, if you wish to.
I’d like to focus on the “Unexpected difference” and would still like the log info that I requested.
Problems typically come from somewhere, and the prior history sometimes sheds some clues.
EDIT:
An example of clues are in Unexpected difference in fileset; unable to delete broken version
where the March 15 job log showed a cleanup (but was it done well?) from March 14 failure.
I’m trying quite hard to get the March 14 server log, but no luck, so unknown how this began.
