A mobile backup is your guarantee that your data on your mobile device is safe and can be recovered in case of corruption or loss.
You can either create backups manually or set up continuous backup.
To set up continuous backup, slide from the left border of the screen to the right, and tap Settings, then turn on Continuous backup. With this setting on, data changes will be backed up automatically.
Please note that on iOS devices backups will run when the application is either open or in background. Backups will not run, if the application is closed.
