> userpanel-userbackup is a non-standard package, and I don't know what it does.
That's the user manager contrib from dungog.
After install access it using
https://youdomain/user-manager & user your own username & password
Admin user configures it to allow users to have access to certain panels in server manager.
There is a panel for the logged in user to backup their home folders to the server. It has selections for backup, restore & verify, similar to the backup to desktop function except just for user homes.
I'm guessing this new expert selected to restore a users home folder and that's what is in the logs.
