Secondary Replication



This article details the Secondary Replication feature for Datto appliances.

Secondary Replication is not available on the ALTO or NAS product line.


  • Datto SIRIS


This feature provides partners in Canada, UK and EMEA the option to have their data replicated from their primary data center to a secondary data center. You can turn this feature on for each Datto appliance from the Device Settings page.

The secondary data center for each location is as follows:

  • Canada → Calgary
  • UK → Iceland
  • Germany → Iceland

Secondary replication within the United States is shared between Datto's bi-costal datacenters.

This feature is enabled by default and can only be toggled on or off. Datacenter replication is determined based on the appliance's geographic location. It is not possible to manually change the target datacenter. Backups replicated to secondary datacenters are only retained at the secondary location for 90 days.

To enable Secondary Replication, access the web UI of your Datto appliance. Click Configure → Device Settings. The Secondary Replication toggle can be found in the location shown in Figure 1.
