Time Machine error. Two of the disks to back up have the same name

Hi koilover,

Please go to Disk Utility (Finder > Go > Utilities > Disk Utility), and then in Disk Utility, "View" > "Show All Devices".

Take a screenshot or photo and please upload here.

Cheers,

Jack

Under Finder all I see is one Macintosh-HD Data drive when I do a get info I figured out by the purgeable of 578.83 that would be the /Volumes/Macintosh HD - Data drive the other drive does not show up so I would not be able to know if there is any data that has not been backed up or not

Delete the last one, by selecting it and hitting the “-“ sign in the toolbar. Make sure all, if any, data is backed up off that drive first.

@Jack, I also have the same error But mine was an upgrade from Mojave to Big Sur I have attached a screenshot of my disk utiltity

Here is a screenshot showing the info of the other HD - Data disk. The main question that I have is why did it create two Data directories one in /volumes and one in /System/Volumes ?

I take it that the one you are talking about is /volumes/macintosh hd -data right?

The one that does not have the “home” icon on the hard drive.

I meant the used data. The real question is how did this happen?

The one that has the Home icon is /System/Volumes/Data which does not show up with Finder

That is correct. The one with the home folder icon shows up in Finder as one Macintosh HD.

Something just went wrong with the update. It happens sometimes.
