Around 4-6 weeks ago the filesystem backup on our primary file server stopped completing nightly backups and started filling the logs with lines like the following:

SQL query 'UPDATE cloud_files SET date_deleted_utc = ? WHERE parent_id = ? AND date_deleted_utc = '99999999999999''. Parameters: '20190403224649, 162767' takes in total: 00:00:05
There are thousands of these lines and the backup job doesn't fail, but runs indefinitely.

I opened a case and was told it's a known issue and development is working on it, but we've been waiting a long time. Has anyone else seen this behavior and found a work around?

Thanks...
