Restore: Starting a Local Virtualization on a Datto Appliance

Follow

Scope

This article explains how to start a local virtualization and backups of a recovery point on a SIRIS device through the Datto appliance GUI.

For a hybrid virtualization on ALTO or SIRIS, see Hybrid Virtualization.

Procedure

Log into the Datto appliance GUI. Then, click the Restore tab.  This will display all the protected machines paired with the Datto device.

1. Under Start A Restore, select the protected machine needed to be restored

2. Under Choose A Recovery Type, select Local Virtualization

3. Under Choose A Recovery Point, select the date to restore. 

4. After all settings are selected, apply Start Virtualization

5. On the following page, configure your virtualization options. For more information about these settings, see Restore: Local Virtualization Options

8. Once the settings are checked, select Apply followed by Start VM. You will be able to see the VM booting in the Screenshot window.

9. After the virtualization boots, you can connect to it with a VNC client by using the address shown in the VNC Connection field. Alternatively, you can use RDP by clicking the Connect Via RDP link. You will be presented with two choices:

  • Connect using local network: Downloads an RDP session file configured to connect to the VM over the local network. This is useful if you are on the same network as the virtualization.
  • Connecting using Datto Remote: Downloads an RDP session file configured to connect to the VM remotely. This is useful if you are not on the same network as the VM.

The Datto appliance will download the RDP file to your default downloads location. The file will be named with the IP address of the agent being virtualized, followed by ".rdp."  For example: 10.0.120.12.rdp

10. Double click the file to open the RDP connection, and allow it to load. To log into the Windows screen, select the Ctrl + Alt + Del option from the appliance GUI.

11. To use the VM as your production machine in a disaster recovery scenario, configure its Windows networking options to match those used by the protected server. Make sure that your production machine is no longer on the network before performing this step.

13. To stop the virtualization, but leave it mounted, click Stop VM. To stop the virtualization and unmount it, click Stop and Unmount.

Backing up Virtualizations

Datto appliances have the ability to back up running restores in the event of a disaster recovery scenario. You can use these backups to restore your production environment and ensure business continuity. To create a backup of your virtualization, see the Create Rescue Agent article. Alternatively, you can perform the following steps.

Agent-Based Virtualizations

To back up a virtualization from a production machine that uses the Datto Windows Agent, Datto Linux Agent, or the ShadowSnap agent, perform the following steps:

  • If the virtualization uses the same IP address as the production machine:
    1. On the Datto appliance, boot the virtualization into Windows or Linux, and configure its networking to your production environment. Make sure that the IP address you assign to the virtualization is the same as the IP address your production machine was using when its backups were running.

    2. In the Datto appliance GUI, navigate to the Protect tab, and click the Configure Agent Settings option for the protected agent. In the page that follows, scroll down to the Advanced category, and click the Repair Agent Communications button, followed by the Force Differential Merge button. Then, return to the Protect tab, and click the agent's Start a Backup button.
Forcing a differential merge will cause the agent to perform a full disk seek across all protected volumes of the VM. This allows the agent to reconcile its incremental backup chain with any changes it detects in the live virtual machine. Due to the manner in which disk UUIDs are handled by virtualization, it is possible that a full backup may occur. Contact Technical Support for assistance if this happens.
  • If the virtualization uses a different IP address as the production machine:
    1. On the Datto appliance, boot the virtualization into Windows or Linux, and configure its networking to your production environment.

    2. Add the agent to the Datto appliance, and start a backup.
Assigning the virtual machine an IP address which is different from the production IP address will cause your Datto appliance to create a new agent dataset, and start a new backup chain for the VM. The first backup it takes will be a full backup. Be sure that your Datto appliance has enough space to store a new full backup before proceeding.

Agentless Virtualizations

To back up an agentless virtualization from a production machine, perform the following steps:

  • If ESXi version 5.1 or newer and a suitable vSphere Standard/Enterprise (Plus) license are available:
    1. On the Datto appliance, start an ESXi virtualization of your production machine.
    2. Using vMotion, migrate both the virtual disks and VM configuration file to your hypervisor. You can do this while the recovery VM is running without the VM crashing.
    3. After the VM has finished vMotioning to the target datastore, contact Datto Technical Support to have the old backup chain re-associated with the newly-restored VM.
    4. In the Datto appliance GUI, navigate to the Protect tab, and click the Configure Agent Settings option for the protected agent. In the page that follows, scroll down to the Advanced category, and click the Repair Agent Communications button. Then, return to the Protect tab, and click the agent's Start a Backup button.
  • If ESX version 5.1 or newer and a suitable vSphere Standard/Enterprise (Plus) license are not available:
The following steps will cause your Datto appliance to create a new agent dataset, and start a new backup chain for the VM. The first backup it takes will be a full backup. Be sure that your Datto appliance has enough space to store a new full backup before proceeding.
    1. On the Datto appliance, boot the virtualization into Windows or Linux, configure its networking, and install the Datto Windows Agent, Datto Linux Agent, or ShadowSnap agent.
    2. Add the agent to the Datto appliance, and start a backup.
    3. When the backup completes, mount the image for export. Copy the image to your datastore.
    4. Recreate the disk descriptor files for the virtual machine that you uploaded.
      Note: Please contact VMware Support if you require assistance with re-creating or troubleshooting disk descriptor files on your hypervisor.
    5. In the Datto appliance GUI, repair agent communications with the protected system, and start a backup for it from the Protect page.
