Was testing out the new WEM and noticed that anything on Backups and Restores was erroring out. Rolled back, and saw the same problem. It ended up being an additional folder had been added into the WEM_Storage folder for the WEM Web Console caused it to error out. (Was when I was creating my easy CVAD setup process) Once I removed the extra folders it worked fine. So if you see any errors and see your backups missing check the contents of that folder.

This for on-prem or Cloud?

ON-prem.
