The process of transferring an image backup of your server to a physical machine is called Bare Metal Restore (BMR).
In the scenario when you have been running a virtual machine after a server crashed and now you’re ready to shut down the VM to get the operations back to the physical server, this would be the next step to follow.
To do the BMR, the first thing you need to do is to create a bootable USB with the BMR software from Datto.
- Get a USB that’s at least 4GB.
- Connect it to your laptop.
- Download Datto Utilities ISO from: https://www.datto.com/downloads/datto-utilities.iso
- Download the latest version from Rufus from: https://rufus.ie/
- Run the imaging process using the instructions from this link: https://kb.datto.com/hc/en-us/articles/115002370806-SIRIS-ALTO-and-NAS-Imaging-a-USB-Drive-with-Datto-Utilities.
After you have this, the next step is to connect the USB in the new hardware and configure the machine to boot from the USB. At that point, follow these instructions:
- Over the Network Options stage you have to assign a new temporary IP address to the BMR environment so this can communicate with the Datto appliance on the network to start transferring the data. This either have to be an IP on the same vlan of the Datto appliance or an IP on the vlan of the server you’re restoring.
Set up the BMR environment following either of the recommendations below. If there are no restrictions on the communication, you should be able to log in to the Datto appliance from the BMR environment, select the server and the recovery point that is needed, and the data would start transferring without problems. If there is an issue in any of the steps of the process, you should try assigning a different IP to the target machine using another of the options below.
- The first option to allow the communication between the target machine and the Datto appliance is to assign to the target machine an IP address on vlan 20 that nothing else is using, so both machines can communicate over vlan 20.
- If the communication cannot be established over vlan 20, try over vlan 10. To do this, you would have to connect the appliance to vlan 10 and apply the target machine a vlan 10 IP as well.
- First connect a network cable to the second NIC of the Datto (from the two Ethernet ports together, it should be the port on the right), and this cable should go to vlan 10.
- Then, log in to the Datto portal, click on the Configure > Networking option, and on the ETH1 section, assign an IP address to the Datto on vlan 10 that nothing else is using. Also, enter the Mask that corresponds to vlan 10.
- After clicking on the Apply button, you’ll see a new button to Reload Networking.
- Once this is done, go back to the target machine and assign another vlan 10 IP address that nothing else is using (this is a different IP than the one assigned to the Datto appliance).
- Then, we need to tell the BMR environment to find the Datto over this new IP by following these instructions on the command prompt:
- From any machine on vlan 10, SSH to the new vlan 10 IP assigned to the BMR environment.
- Login to the environment using credentials:
- UN. datto
- PW. datto
- Enter command: sudo –i
- Enter command: bmrctl system:reset
- Enter command: bmrctl host:new 10.XX.10.XX [Enter new Datto IP address on vlan 10]
- Enter command bmrctl host:login datto datto100 [Enter your Datto portal login]
- Open the browser and manually redirect the BMR environment to the agents page, by entering this URL in the address bar. Just make sure to update the IP to the vlan 10 IP of the target machine: http://10.74.3.44/bmr/agents/
- From there, you should be able to go through the rest of the steps.
- Another option to allow communication between the Datto appliance and the target machine is to prepare a predetermined IP that has been wide open by Trustwave. This rule would only be created temporarily while the BMR process is performed and after that it should be removed.
- Example:
- Source is Datto machine: 10.28.20.15 – Destination is the target machine: 10.28.10.6. Request to Trustwave to allow communication for both IP incoming and outgoing.
- After confirming the network in the first step, you will see the Checking for Updates message. Datto recommends allowing the environment to download and apply updates.
- When the updates are completed, the page will redirect to the Datto Utilities application menu. Select the application you would like to launch. In this case choose BMR.
- Select the Datto appliance that contains the restore information. When prompted, log into the device with the user credentials you created to access its GUI. Then, click Next.
- Select the protected system that you want to restore. For encrypted agents, you would be required to enter the password to proceed. Then click on Next.
- Select a recovery point to restore to the target. If you created a Rescue Agent for the Disaster Recovery virtualization, you can apply any changes made to the VM during the BMR to the production machine by checking the Continuously Mirror box. Then, click Next.
- Next window, choose the option Automatic Partition.
- Verify the partition layout. Then, click Clone Data.
- You will be prompted to confirm your selection. Type FORMAT in the confirmation box, and then click Confirm.
- The Bare Metal Restore environment will begin the process of cloning data to your target machine. This process may take some time to complete, depending on how much data you are moving.
- When you are ready to bring the production machine back online, click Stop Mirroring, followed by Finish and Reboot.
