OK, I did some more testing, and it's pretty weird. It is NOT an issue of scheduled back-to-back backups not working. It's an issue of ONE scheduled backup not working. My two backups are (1) to a Western Digital Passport SSD, and (2) a Western Digital Sabrent spinning disk drive. When I schedule both, only the SSD backup happens. The Sabrent JUST DOESN'T happen. Nothing happens at that scheduled time. SuperDuper doesn't even open. When I do manual backups, each backs up properly. For some reason I cannot successfully SCHEDULE the Sabrent drive.
In Disk Utility, when I look at these disks, they all seem to be set up the same way. GUID partition map, APFS. What's going on???
