Jul 6, 2021 at 16:49 comment added Bob Werner Time Machine makes a local snapshot every hour or so, even if the Mac is sleeping, and even if no TM disk is plugged in. BigSur Help for 'local snapshot' says "Local snapshots are only stored on disks using Apple File System (APFS) when Back Up Automatically is selected in Time Machine preferences."
Jul 5, 2021 at 23:42 comment added Gilby @dcinderdiu It is easy to check for TM being the cause - just look at the folders (or volumes) on the TM disk. As benwiggy says, the Mac will be doing things whilst supposedly sleeping.
Jul 5, 2021 at 12:53 comment added benwiggy Have you looked through the logs to see if any messages correspond with those times?
Jul 5, 2021 at 11:41 comment added dcinderdiu As stated earlier, I have the Power Nap option set to off, so the computer really can't be checking for any time machine backups
Jul 5, 2021 at 11:20 comment added benwiggy It's possible that the TM process launches, checks to see if there's a disk, and then quits.
Jul 5, 2021 at 10:33 comment added dcinderdiu I don't have a backup plugged in to my computer at night, nor does the machine backup remotely...

Jul 5, 2021 at 9:24 comment added benwiggy I don't know for certain, but I wouldn't be surprised if Macs were still doing things while sleeping, even with Power Nap off.
Jul 5, 2021 at 9:16 comment added nohillside Should this happen with Power Nap disabled?
