Time Machine not working

Time Machine on my iMac (Mojave) has not backed up for several days. Restarting doesn't help. The external HD 'Time Machine Ext' is connected; its icon appears on the desktop.


Message says:


"Time Machine couldn't complete the backup to "TIME MACHINE Ext"


Unable to complete backup. An error occurred while creating the backup folder."


I would attach the screen shots but there does not seem to be a way to do so.


Thanks for any help!



iMac 27", macOS 10.14

If you don't need your old backups, the easiest and fastest way to solve this would be to reformat your external hard drive and start over.
