On "All devices" screen click on a device you wish to backup.
Click on "Backup" to go to the settings screen.

A backup setting's form will be displayed.
Warning: If you choose to turn on the encryption, a password set up here will be needed to recover a server from the backup. Please be advised that this password cannot be reset nor retrieved, and if you forget or lose it, there will be no way to access the backup data.
After creating the backup plan, you can also run it at any time without waiting for the schedule.
