After update to 4.5 from 2.5, backups no longer work

Hi all.

I’ve done two things in the last week, upgrage to 4.5 CE from 2.5 and increase the bucket limit from 10 to 15.

Then I noticed that the backup wasn’t running and it seems to just hang on one of the buckets.

This is a single node setup with 10 buckets running on Windows. Any ideas or help?
