Turn off Backup Notification.

This has been asked several times already, but no satisfying answer. How do I turn off notification of needing Backup to iCloud when I am out of the country and out of Wifi range for a month or longer at a time? Yet I do NOT want the phone to backup to my work-laptop. I can turn off app update notifications, how do i turn off the Backup notification. Or perhaps change the time-up so that it does not appear after just a few days?
