Prevents a backup (including a backup to a local disk) if the device is connected to the Internet by using a connection that is set as metered in Windows. For more information about metered connections in Windows, refer to https://support.microsoft.com/en-us/help/17452/windows-metered-internet-connections-faq.
As an additional measure to prevent backups over mobile hotspots, when you enable the Do not start when on metered connection condition, the condition Do not start when connected to the following Wi-Fi networks is enabled automatically. The following network names are specified by default: "android", "phone", "mobile", and "modem". You can delete these names from the list by clicking on the X sign.
Example
Data is backed up every workday at 21:00. If the device is connected to the Internet by using a metered connection (for instance, the user is on a business trip), you want to skip the backup to save the network traffic and wait for the scheduled start on the next workday.
As a result:
(1) If 21:00 comes and the device is not connected to the Internet by using a metered connection, the backup will start immediately.
(2) If 21:00 comes and the device is connected to the Internet by using a metered connection, the backup will start on the next workday.
(3) If the device is always connected to the Internet by using a metered connection on workdays at 21:00, the backup will never start.
