After installation, I set this plugin up to do a manual backup and send it as an attachment to my email before going to bed. The next morning it still said 0%. So I tried a manual backup downloaded to my computer and it did the same thing. So I thought, maybe I need to register; after registering and adjusting my settings for an online backup, it got to 78% then stopped. I left it alone for 15-20 minutes and it never got any farther. A few other times Online-backup remained at 0% completion and once got to 83% before quitting. I deactivated this and am now moving on, wishing I hadn't given my email and wasted time registering.
