This article gets you started with the USB BMR process for disaster recovery. For best results, review the Datto Disaster Recovery Guide before you get started.
The Datto Utilities version of USB Bare Metal Restore is only available for Datto appliances running the Datto IRIS 3 (Ubuntu 16.04) OS. For Datto IRIS 2 (Ubuntu 12.04) appliances, or if you are attempting to recover a 32-bit system, image the USB drive with the Legacy BMR ISO
environment, and follow the Legacy Bare Metal Restore
If you are performing a BMR from a VM on a Datto appliance, make sure that all volumes have been backed up successfully, and are restored to the production machine, before you remove the VM from the Datto appliance. Otherwise, you can lose data.
A Bare Metal Restore will cause the target server to perform a full backup when the restore finishes. Depending on the speed of your network, you might need to order a RoundTrip
to move this backup to the Datto Cloud.
Requirements for the target hardware:
- Must be able to boot from USB
- Must be on the same network as the Datto device
- Must be 64-bit hardware
Any OSs will be restored as a single partition. If you need a software RAID, you must restore the OS to a single partition and then configure the other Windows partitions as a software RAID.
Support of RAID hardware is dependent on compatibility with the Bare Metal Restore environment's kernel and version. See Ubuntu's list of certified compatible hardware
for compatibility guidelines.
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.
