You can see the backlog: right-click Calibre Library: Library Maintenance: Library Metadata Backup Status.
I think one of the sources is having troubles (?Goodreads?)
@theducks - with 300 books the reading of the updates from the database by the backup process maybe contending with the process that is updating the database with the remaining reviewed downloads.

When does the writing of the database changes to the .opf files (backing up) start in this scenario - after the first update is applied or after they all been applied. If former maybe database contention is a possibility.

I'm sure I've seen a post in relation to one of the plugins that suggests limiting the number of books in a batch to - 50ish.
