Drive name changed – Time Machine does not back up any more

Hey there,

the name of my WD network drive changed from MyCloud-GNExxx to MyCloud-GNExxx-2, so Time Machine does not recognize it any more as its backup volume.

I use file vault and registered as a guest user, and for a few week, everything worked fine.

Any way to undo and prevent further name changes? Thank you for any advice!

Best,
Klaus
