This article explains the process of booting a target machine from a USB drive imaged with Datto Utilities containing Datto's Bare Metal Restore Environment, and starting a Bare Metal Restore (BMR).
This article assumes that you have already imaged a USB stick with the Datto Utilities. If you have not already done this, see the article Imaging a USB Drive with Datto Utilities.
On the target machine:
Plug the USB drive into the target machine. We recommend that you use the USB ports that are directly connected to the motherboard. Usually, this means using the USB ports on the back of the machine. Datto also recommends using at least a USB 2.0 port, if available.
Boot the target machine into its BIOS or Motherboard Firmware (uEFI) settings. Configure it to boot from the USB drive. Then, reboot the production machine.
On EFI systems, you must temporarily disable EFI booting in order to boot from the USB drive.
When the target machine finishes booting, the Datto Utilities environment will attempt to autoconfigure networking via DHCP. If the environment cannot obtain an IP address, you will be prompted to manually configure networking, as shown in Figure 1.
Figure 1: Network Configuration
Once the networking check succeeds, you will see the Checking for Updates message shown in Figure 2. Datto recommends allowing the environment to download and apply updates.
If the updater is unable to complete, and exits with a failure state of "Error during stick update: Unable to determine if stick is out of date," this indicates that the imager cannot reach Datto's servers to check for updates. You will need resolve any issues in the production environment that may be preventing the target machine from configuring networking. Make sure that the target machine's environment meets the SIRIS, Alto & DNAS Networking and Bandwidth Requirements. Then, click Retry.
When the updates complete, you will be redirected to the Datto Utilities menu. Select the BMR option.
Select the 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 from, and click 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 in the VM during the BMR to the production machine by checking the Continuously Mirror box. Then, click Next.
The wizard will calculate minimum volume sizes, and then display the Partition Machine screen shown in Figure 7.
Click Automatic Partition, and proceed to the Data Transfer article. Alternatively, if you need to manually partition the target machine, click Manual Partition, and proceed to the USB Bare Metal Restore: Advanced Partitioning article.
