USB Bare Metal Restore: Booting the target machine from USB

Follow

Scope

This article explains the process of booting a target machine from a USB drive containing the Datto BMR environment.

Prerequisites

This article assumes that you have already imaged a USB stick through the Datto device's Remote Web interface. If you have not already done this, see the article USB Bare Metal Restore: Getting Started.

Procedure

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.

Boot into the BIOS or Motherboard Firmware (uEFI) settings. Set it so that the machine boots off of the USB drive. Then, proceed to reboot the machine off of the USB drive.

On EFI systems, you must temporarily disable EFI booting in order to boot off of the USB drive. The Datto USB BMR environment is not EFI-bootable.

When the target has finished booting, take note of the IP address at the bottom of the page, as shown in Figure 1.

You can disregard the message "Forcibly Updating BMR software."

NOTE:

Certain server environments may not support booting to the BMR GUI. Instead, a Datto BMR command-line interface may appear, prompting for a user name and password. If this happens, enter the username datto and the password datto, which grants access to the BMR command-line. From there, run the following commands to determine the IP address of the BMR:

  • sudo -i
  • ifconfig

The IP address is listed after inet addr, as shown in Figure 2.

Then, from another machine on the same LAN:

Open a Chrome or Firefox browser window to the target machine's IP address. You will see the page as shown in Figure 2.

Click Get Started. You will see the window as shown in Figure 3.


Figure 4 - Device Selection

Select the Datto device that contains the restore information.

When prompted, log into the device with the user credentials you created to access its web UI.

You will then see the window as shown in Figure 5.


Figure 6 - Protected Machine ("Agent") Selection

Select the protected system that you want to restore from. Then, you will see a list of recovery points, as shown in Figure 6.

Select the healthy recovery point to restore to the target.


Figure 8 - Mount Failure Error

If you encounter the error shown in Figure 7, follow these steps:

From an SSH client, open a connection to the target machine's IP address. Contact Datto Technical Support for login credentials to the BMR environment.

Via ssh, type sudo df -h

If you see a drive mounted to logSambaShare, enter the following commands:

sudo -i

umount /run/shm/logSambaShare/

Run df -h again to make sure that the share is not in the list.

In the browser, select the recovery point again.

When the process is successful, you will see the screen as shown in Figure 8.
