It will be an album that is tripping it up.

Couple of suggestions ...

Use the Sooloos interrogator to compare what is in the backup folder vs what is in the library.

This will identify the 22 remaining. Export them all. Then delete them and reimport. Rerun backup.

You might also query the backup folder to see the last folder created. See if you can see anything odd/incomplete in it. Open the files in notepad to see what the album is. This could also be the album causing the issue. Export/delete/reimport.

Failing all that... search the forum for other ways to backup.
