Hi Ken,
Autobackups have never been allowed. It's always been off.
Strange thing is now that I've returned back from lunch there's a whole bunch more folders and logs created. What other mechanisms would initiate backups aside from the Autobackups and someone doing it interactively on the website and of course, my own CLI scripts? Are there any other mechanisms that would perform a backup?
One thing I have discovered is that if I perform a backup of a single activity by first clicking on the activity and using the Backup menu option for that specific activity, the backup performs accurately without errors. I'm not exactly sure if I can include more than one activity but I'm about to begin trying various partial backups to see if I can whittle down to the offending activity, block, or whatever.
Thanks for sharing your time with me.
