Calendar, Contacts, Notes

Feature description

I would like to have a backup frequency setting within the Manage Automatic Backups dialog that specifies the time between each backup call.

Why do you want this feature?

It's related to the problem that I have no control over the backup frequency, which seems to be every morning. I want the app to backup the calendar data every x days, but there's no option to set it that way.

Additional information

To get more space in the dialog, we could move the "Export events", "Export tasks" and "Export past entries too" checkboxes to another dialog (like the "Manage event types" one).
