Imaging a USB Drive with Datto Utilities



This article describes the method for imaging Datto Utilities onto a USB drive. The Datto Utilities application includes the Bare Metal Restore (BMR) and SIRIS Imaged environments.

The Datto Utilities version of the Bare Metal Restore (BMR) environment 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 process. You can see which version of Ubuntu your Datto device is running on the Advanced Device Status page.
Datto Utilities is incompatible with DVD media.


You should have the following items available when starting this process:

  • USB drive that is at least 8GB
  • Datto recommends using the latest version of Rufus to image the drive.
    • See the Additional Resources section of this article for information about alternative imaging methods.
Using Rufus will format your USB drive entirely. Make sure the USB drive contains no valuable data before imaging.

Obtaining the ISO

You can download the Datto Utilities image (.ISO) from the Datto Downloads page by select the download link for SIRIS Imaged Installed 16.04 or BMR 16.04. Once the image file has downloaded, proceed to the next section.

Imaging the USB Drive with Rufus

Once you have obtained the image file, proceed as follows.

1. Attach the USB drive to your machine, and open Rufus. If you receive the following prompt, select Write in DD Image mode, and click OK.

You must use DD Image mode. Using ISO mode creates the Datto Utilities environment as read-only, which can cause the Bare Metal Restore process to fail.

2. Choose the following settings for imaging your USB Drive:

  • Device: Choose the drive letter which corresponds to your flash drive
  • Partition Scheme: Choose MBR partition scheme for BIOS or UEFI
  • File System: Choose NTFS or FAT32 (Default)
  • Cluster Size: 16 kilobytes
  • Format Options: Select Check device for bad blocks (1 pass),Quick FormatCreate a bootable disk, and Create extended label.

3. Select the image file for use, and then select DD image.

4. Select Start. Rufus will notify you when imaging has completed. When it finishes, you can safely remove the USB drive. 

Additional Resources

If you experience difficulty with imaging the USB drive by using Etcher, you can use Rufus (for Windows platforms) or the UNetbootin utility (for Mac or Linux platforms) as fallback solutions.

For Etcher instructions, see the next section of this article. For UNetbootin instructions, see the UNetbootin section of this article.

Using UNetbootin or Etcher will format your USB drive entirely. Make sure the USB drive contains no valuable data before imaging.

Imaging the USB Drive with Etcher

1. Attach the USB drive to your machine, and open Etcher. Click Select image, and select the Datto Utilities ISO.

Imaging the USB Drive with UNetbootin

If you are imaging from a Mac or Linux machine, you can use the UNetbootin utility to attach the ISO. Follow the Installing Other Distributions Using UNetbootin section of the article at this link to format the drive.
