INTRODUCTION
This feature on Logi Options allows you to backup the settings of your Options supported device
automatically to the cloud after creating an account. If you are planning to use your device on a
new computer or wish to go back to your old settings on the same computer, log into your
Options account on that computer and fetch the settings you want from a backup to setup your
device and get going.
HOW IT WORKS
When you are logged into Logitech Options with a verified account, your device settings are
automatically backed up to our cloud by default. You can manage the settings and the backups
from the Backups tab under More settings of your device (as shown in the screenshots below):
