I'm having trouble with scheduled backups in v3.2.5 on an M1 Mac mini. I'm running the latest version of Big Sur (v11.2.1).

I'm backing up the Data volume to an external 500GB SSD. I'm backing up an external 6TB hard drive(s) RAID 0 array to an external 6TB hard drive. All of the external drives, the SSD and the spinning disks, are connected via Thunderbolt.

Manual copies work fine but the scheduled copies don't run at all. I thought that maybe the machine was in sleep mode at the appointed time so I scheduled a 'wake' event in Energy Saver pref pane for a few minutes before the scheduled tasks. The tasks still didn't launch.

I noticed the following in the Mac mini's system log:

Feb 19 22:52:04 mac-mini com.apple.xpc.launchd[1] (com.shirtpocket.backupbytime[5750]): Service could not initialize: 20D74: xpcproxy + 23712 [839][75A06642-92A3-341F-9E53-0360AAB45CA0]: 0x1
Feb 19 22:52:04 mac-mini com.apple.xpc.launchd[1] (com.shirtpocket.backupbytime[5750]): Service exited with abnormal code: 78

It seems like this may have something to do with my issue but I don't know what to do with this information. What should I do next in my troubleshooting?

Update: I added SuperDuper!.app to System Preferences > Security & Privacy > Privacy > Full Disk Access. I have not tested a scheduled backup since making this change...yet. - ct
