SpiderOak ONE and Groups are designed to gracefully deal with network outages, so you don't need to manually pause if you are turning off your computer, or moving around and intermittently losing Internet connection. The backup application will pick up where it left off when it regains connection. Most people never need to manually pause a backup.
