Good concept, nice interface…doesn’t work

I installed this plugin on my site and used it with difficulty making backups. I would manually start the backup and it would show progress, but then stop before completion. After a few tries, I was able to successfully backup my site. Then I scheduled weekly automatic backups. The day and time came and went, but no backup. Next I tried to use Total Upkeep to migrate my site to a new domain. I tried numerous times, but it locked up every time before completion AND it corrupted the WordPress install on the new domain. I had to delete all files/database and start over. After several tries I gave up and used a different plugin with similar functionality. Has worked like a charm with no problems.
