Broke my website

I’ve been using this plugin for a while, but it’s very unreliable – there’s always some issue. First it was batch scheduling, can’t remember what was wrong with it, but it prevented the plugin from working. But it gets worse – the last time I restored my website, it broke it completely and I had to get a backup from my hosting provider. Meaning all my changes and work were gone, too. There’s an issue when you press the “Delete old backup directories” button – it messed everything up for me. Now I’m afraid to press it:)
Other than these issues, it’s a great plugin, but really, if you can’t reliably restore a backup, then what’s the point of this?:)
