you should add the possibility to turn off email only for automatic backup and keep email is backup is mannualy scheduled from webuzo, this because the page alert you can leave the page and you will receve an email when backup are ready so if you change the page you will unable to know when the backup is finished.
I want receive this kind of email and not receive email on automatic backup.
Maybe you should decide to not receive only specific application email alert of backup.
