Backup device settings to the cloud in Logitech Options+****

INTRODUCTION
This feature on Logi Options+ allows you to backup the customization 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 set up your device and get going.

HOW IT WORKS
When you are logged into Logi Options+ with a verified account, your device settings are automatically backed up to the cloud by default. You can manage the settings and the backups from the Backups tab under More settings of your device (as shown):

Manage settings and backups by clicking on  More  >  Backups:

AUTOMATIC BACKUP OF SETTINGS  — if the  Automatically create backups of settings for all devices  checkbox is enabled, any settings you have or modify for all of your devices on that computer are backed up to the cloud automatically. The checkbox is enabled by default. You can disable it if you don’t want the settings of your devices to be backed up automatically.

CREATE A BACKUP NOW  — this button allows you to backup your current device settings now, if you need to fetch them later.

RESTORE SETTINGS FROM BACKUP  — this button lets you view and restore all the available backups you have for that device that are compatible with that computer, as shown above.
The settings for a device are backed up for every computer that you have your device connected to and have Logi Options+ that you are logged into. Every time you make some modifications to your device settings, they get backed up with that computer name. The backups can be differentiated based on the following:
Name of the computer. (Ex. John’s Work Laptop)
Make and/or model of the computer. (Ex. Dell Inc., Macbook Pro (13-inch) and so on)
The time when the backup was made
The desired settings can then be selected and restored accordingly.

WHAT SETTINGS GET BACKED UP
– Configuration of all the buttons of your mouse
– Configuration of all the keys of your keyboard
– Point & Scroll settings of your mouse
– Any application-specific settings of your device

WHAT SETTINGS ARE NOT BACKED UP
– Flow settings
– Options+ app settings
