At the end of a backup, a pop up shows errors in the thousands, yet when clicking to show the log, it only shows a few dozens warnings.
If I want to actually see all the errors, I have to go to the About screen and select:
“Log data from the server: Live: Select a log level and see messages as they happen: Warnings”
and have them write to the screen them in real time. If I click away from that scree, they are gone!
