SD back up failed on Big Sur (Intel)

I tried to backup all files (erase and backup) of the Data volume of a Mac mini (Intel) running Big Sur (11.2.3) using SD 3.2.5. The back up failed towards the end.

When I used the same process to back up a Macbook M1 to another APFS volume on the same external drive, it was successful. What should I do?
