SIRIS, ALTO, and NAS: USB Bare Metal Restore: Beginning the Restore



This article describes the process for starting a USB Bare Metal Restore (BMR).


  • Datto Bare Metal Restore


A Bare Metal Restore is used to restore a backup point to new hardware.


This article assumes that you have already imaged a USB stick with the Datto Utilities, and that you are booted into the Datto Utilities environment. If you have not already done this, see the Imaging a USB Drive with Datto Utilities and Booting a Target Machine with Datto Utilities articles.


1. In the Datto Utilities environment, select the BMR option.

2. 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.

3. Select the protected system that you want to restore from, and click Next.

4. 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.

Continuous mirroring requires automatic partitioning to ensure adequate space for incremental changes. You will not be able to select the Manual Partition option in the next step if the Continuously Mirror option is enabled.
In the event that the mirroring process is interrupted by an unexpected crash or a reboot of the production machine, it can automatically resume. If the most recent snapshot the mirroring process captured is unusable because of the crash, the process will take another snapshot, and perform a differential merge between the new snapshot and the last good snapshot to reconcile differences between the two points.
Continuous mirroring does not work with encrypted agents and is unavailable on ALTO and NAS products.

5. The wizard will calculate minimum volume sizes, and then display the Partition Machine screen shown in Figure 5.

6. Click Automatic Partition, and proceed to the Data Transfer article. Alternatively, if you need to partition the target machine manually, click Manual Partition, and proceed to the USB Bare Metal Restore: Advanced Partitioning article.
