SIRIS, ALTO, and NAS: Configuring an Appliance for SIRIS Private Replication



This article describes the process to configure a Datto appliance to act as a node in a SIRIS Private configuration. Before performing the steps outlined in this article, see our Getting Started with SIRIS Private article for pre-deployment information.


  • Datto SIRIS


Required Hardware

SIRIS Private configuration requires at least two Datto SIRIS devices:

  • One SIRIS to act as the source device, which will perform backups of a protected machine
  • A second SIRIS to serve as the target device, which will act as the storage node for replicated copies of the source device's backups

Service Plans

  • The source device must be on a SIRIS Private service plan.
  • The target device may use any billing plan.

Networking Requirements


  • The source device and target device must be associated with the same client within a reseller.


1. Set up and register the source device and the target device.

2. Install our backup agent software on the systems that you wish to protect, or configure them for agentless backups.

3. Access the Datto Partner Portal. Log into the reseller that you'd like to manage.

4. Select Status → BCDR Status, as shown in Figure 1.

7. From the Replication Details card, click Authorize Target SIRIS.

8. Click the Select Target SIRIS dropdown, and select the appliance that you'd like to use as a storage node. Then, click Authorize.  Refer to Figure 4 for a demonstration of the authorization process.

9. Once you see the Successfully authorized device notification, click Close.

10. The target SIRIS will appear in the Replication Details card's device list, along with details about the total storage space it has available and the total number of agents and shares replicating to it. For more information about this card, consult our Device Details article.

11. You can add as many target SIRIS appliances as you'd like. To do so, repeat Steps 7 through 9 of this article.

  • To remove a target SIRIS, click Deauthorize. You cannot deauthorize a device if it has any systems replicating to it.

12. When you've finished adding authorize targets, access the GUI of the source SIRIS, and launch the Protect a System wizard to begin adding the systems you'd like to protect and replicate to the target SIRIS. Refer to our Protecting a System article to learn more.
