Managed Backup Failing at 21% Every Time

I had accidentally deleted my website over a week ago. I thought that I’d been backing it up to Updraft Plus, along with Snapshot but I lost everything.

I have tried to get my managed Backups to work but I was unable to. And I ‘ve just rebuilt the site again over the last three days. I need to make sure that it’s backing up somewhere. I need help in determining why nothing is backing up. When I get to 21% the backup stops on its own. I’ve tried four times in a row.
