Storm season is back, bringing with it the potential for significant weather events. If you have clients in areas prone to infrastructure disruption, visit the Disaster Recovery Resources guide for preparedness information. Datto recommends performing proactive disaster recovery testing to mitigate potential downtime.

Disaster Recovery Testing: Creating A Sandboxed Local Virtualization



This article explains how to test virtual machines in a sandboxed environment.


  • Datto SIRIS
  • Datto ALTO


When configuring virtualizations for sandbox testing which requires the virtual machines to be able to communicate with each other, you will need to use IP schemes and a subnet that have no association with the production network. Otherwise, the VMs could cause networking or domain conflicts in the live environment.


Follow these steps to perform a sandboxed local virtualization:

1. From the Datto appliance GUI, click the Restore tab.

2. Select the protected system you would like to restore.

3. Choose the Local Virtualization recovery type.

4. Select the Recovery Point to restore from.

5. Select Start Restore.

6. You will be redirected to the Local Virtualization page shown in Figure 2.

7. Set the Local Options for the virtualization. In the Network Options, select Firewalled on Private Subnet (or Firewalled on Private Subnet with No Internet Access, if you prefer the virtualization to be restricted to the VLAN). Uncheck the Create Rescue Agent option unless you wish to take backups of your local virtualization.

8. Click Start VM.

9. Click Open in browser to connect to your virtualization via a browser-based VNC session (recommended). Then, proceed to Step 11 of this article. If you prefer to use RDP to connect to the virtualization, see Step 10 of this article for instructions.

10. To connect to your virtualization using RDP, click Connect Via RDP. If you are on the same LAN as the Datto appliance, select Connect using local network. If you are not on the same LAN, click Connect using Datto Relay. An RDP file will download to your local machine. Open the file to connect directly to the virtual machine.

11. Configure the VM's networking settings, including an IP scheme that differs from your production environment.

12. Repeat steps 1 through 11 for each VM that you'd like to add to the VLAN.

13. Verify the connectivity between the VMs, and then check their connectivity to the Internet.
