Unable to include external media drive in time machine backup I have recently moved my apple photo library to an external hard drive to save space on my internal SSD, however i would obviously still like this external drive to backup with the rest of my computer. However it appears i am unable to take this drive off the excluded list (as shown below), does anyone know how i can remedy this?
Cheers.
Best guess is the drive is the wrong format.
Time Machine won't back up NTFS, FAT or ExFAT.
APFS should work, but 'safest' is HFS+ [MacOS Extended, Journaled] using GUID, not MBR. These options are available in Disk Utility.
You will not be able to change the format &quot;live,&quot; you will need to copy this data elsewhere, then erase the drive &amp; then copy back to it afterwards.
