Getting this message since June 8 update with failing backup
Two of the disks to back up have the same name. Rename one of the disks named “Macintosh HD”.
How can I correct as there is only 1 Mac HD on the system??
It's not clear, do you have 2 backup disks?
Are you freshly on Catalina?
Have you removed the backup Disk & added again?
There is a single backup disk, but the "Macintosh HD" drive is listed for backup twice and this is causing an error that indicates you can't backup two disks with the same name. In actuality there is only 1 volume with that name. I don't see where or how I I can delete it in the time machine setup. Catalina update was done a few weeks back...not sure the backup failures started at that time or afterwards...
What is the name of the external drive?
In TM Prefs, click on Select Disk, highlight one at a tome & click Remove for each one listed.
Rename the external Drive if there is one, then add that.
