Hi Michael
I am using your plugin with the premium extensions ZIP and Email.
Since some time (a month or so) I've noticed that the backup is not effective: they seem to never end.

As you can see, there is no "backup completed" anymore.
The other problem is that I don't get notified either by email. So in the end, nothing works.
Could you maybe help me there? What kind of log can I provide you?
Thank you very much
Manu
