Passport for Mac
I keep getting the error message 'Unable to complete backup. An error occurred while creating the backup folder.' Sometimes I can solve this by restarting the iMac, but it doesn't always work. Any ideas?
iMac 21.5″, macOS 10.14

Check its format type, it should either be APFS or Mac OS Extended. You can use either Disk Utility or select it in Finder and right click it and you will see a box that shows among other things its format type. If it is not formatted correctly, use Disk Utility to Erase (meaning all data on it will be lost) to APFS.
