This article describes the USB BMR process for disaster recovery. The Bare Metal Restore utility is a tool to restore downed servers.
For best results, review the Datto Disaster Recovery Guide before you get started.
The Bare Metal Restore feature is not intended to be used as a deployment tool. To deploy a new server instead of recovering a downed one, install the new server's operating system, and then use the Direct Restore Utility to migrate its data.
Requirements for the target hardware:
- Datto recommends verifying that the target hardware is healthy, including checking the SMART values on hard drives to ensure healthy target disks.
- Must be able to boot from USB
- Must be on the same network as the Datto device
- Must be 64-bit hardware
- Bare Metal Restore to EFI Linux agents is not supported. See the Installing the Datto Linux Agent article for more information.
- If you update a protected machine to Mac OS X to version 10.12.5 from an earlier version, you may need to force a new full backup of the agent for continued compatibility with the Bare Metal Restore process.
- Due to the wide range of touchpad drivers, custom drivers, and hardware configurations, support for Bare Metal Restores on laptops and all-in-one workstations is 'best-effort' only.
- Touchscreens may not work after a Bare Metal Restore until you manually reinstall their drivers.
Figure 1 illustrates the data flow for the Bare Metal Restore solution. See the SIRIS, ALTO and DNAS Networking & Bandwidth Requirements article for more information.
You should have the following items available when starting this process:
- USB stick that is at least 8 GB
- We will automatically detect storage controllers and inject them as needed. You may still want to collect any other drivers to apply after the imaging is complete.
- If your backups are encrypted, then you will need the encryption passphrase for the protected system that you are restoring.
Image the USB Drive
- Download the Datto Utilities Image, and image the USB stick. For more information about this process, see Imaging a USB Drive with Datto Utilities.
- Once the imaging process completes successfully, unplug the USB stick, and proceed to the article USB Bare Metal Restore: Booting the target machine from USB.
