Apple SSD Data Disc
To clean up my MacBook Pro (Intel) I have erased the disk and reinstalled Big Sur.
When I try to backup to Time capsule via time machine I get an error that there is 2 disc withe the same name.
When I open Disk Utility I get I can see that files are spread across two disks with the same name.
Screenshots attached.
