Thanks for creating such a simplistic and well coded plugin, it works just as it should.
I was wondering whether you had plans on implementing a user friendly way to set the back-up location?
Personally I think that would be a fine addition to the plugin as it would allow you to keep files outside of the web-root, a relatively simple feature that would not clog up the settings of the plugin, and if not could easily be set to use the default path.
I know a few developer friends of mine who use your script (who recommended you) and they agree that this feature is missing as would be gratefully received if integrated.
Either way, I will be upgrading to pro version if not for any other reason than to support its continued development.
Keep up the good work,
