Appliance data stores are essential to the acceleration service. They store data references that help reduce and speed up WAN traffic. When data enters the appliance, it's broken into segments, indexed, and stored. If the same data is seen again, only references to it—rather than the full data—are sent across the WAN. This significantly reduces bandwidth use and improves performance.

Data store settings let you configure options like encryption, syncing with other appliances, branch warming, and notifications for when the store wraps around.

After changing these settings, you need to restart the acceleration service. To confirm the changes are working, check the Networking or Optimization reports.
