Remote backup task quit working : constraint failed UNIQUE constraint failed: Remotevolume.Name, Remotevolume.State

Found a UNIQUE constraint clue. I’d been wondering if there was a duplicate name, and I found one.
SELECT Name FROM Remotevolume gave 2543 rows
SELECT DISTINCT Name FROM Remotevolume gave 2542 rows, so there’s a duplicate somewhere
SELECT Name FROM Remotevolume GROUP BY Name HAVING COUNT(Name) > 1

The Size and Hash are familiar, but the Name has not been mentioned before and isn’t in the file list therefore this finding might be going nowhere but it needs a more expert opinion and none is available.
