Fixing backup module

[Me.B]

why broken on freebsd? Didn't target it.

For me shell is more efficient. No time out risk, less overhead under php. Also I can do the same for windows! ( we could too for freebsd ). Notice I think more about wiping out zsudo and tightening the security to lock down totally sentora.

And also I was preparing to work on installers so I wanted a quick fix. It would easily as I said scale to per user settings. Love how it hack mysql into bash.

I can imagine later a restore script that could be triggered by users too... Imagine you can restore the backup in 2 clicks. It's not so hard to do.
