This article refers to the Barracuda Backup Legacy Release firmware or newer, except where noted. Bare metal recovery allows you to restore a complete Microsoft Windows system, including data, settings, applications, and operating system, onto a new computer on which nothing is installed. Caution The bare metal recovery process overwrites all existing data on the system to which you are restoring the data; therefore, bare metal recovery is recommended only when no other recovery option is available. This process rebuilds the target computer or server to its original system setup. A bare metal restore is intended to be used for restoring to similar hardware. All system volumes and system state must be backed up in order for bare metal recovery to be possible. Requirements You must have an existing backup of a system that uses one of the following Microsoft operating systems: Microsoft Windows Server 2016 Microsoft Windows Server 2012 R2 Microsoft Windows Server 2012 Microsoft Windows Server 2008 R2 Windows 2008 Server Windows Small Business Server 2011 Windows Small Business Server 2008 Windows Vista Windows 10 Windows 8 Windows 7 Additionally, you must have all of the following: Barracuda Backup Server firmware version 6.1 or higher; Barracuda Backup Bare Metal Live CD 6.1 or higher (available from the System > Software Downloads page); and Administrator rights to the Microsoft Exchange Server. Bare Metal Live CD Use the following steps to download the Bare Metal Live CD boot media; select the appropriate bit version for the OS you are planning to restore. For example, if you are restoring a 64-bit operating system, you must use the 64-bit version. 1. Log in to Barracuda Backup and go to System > Software Downloads. Download the Bare Metal Live ISO file to your local system. 2. Burn the Bare Metal Live ISO file to a CD. 3. Boot the system you want to restore using the Bare Metal Live CD you created in step 2. 4. Read the onscreen warning: 1 / 9
5. 6. To continue with the Bare Metal restore, click Next. Set up the Network configuration: If you have DHCP enabled on your network, an assigned IP address displays in the IP Address field. If DHCP is not enabled, clear DHCP, and enter the IP Address, Subnet Mask, and Default Gateway: 2 / 9

12. 13. Click Start Restore. For the system booted using the Bare Metal Live CD, a list of volumes that are recoverable displays: 14. Select the volumes you want to recover. You cannot deselect boot and system volumes as these are required for the Bare Metal restore. If you choose to restore to a server that does not have identical volumes as the original machine the data was backed up from, the Barracuda Backup appliance will still attempt to restore all drives even though you may have only selected one of these on the Bare Metal Restore screen. The restore will throw errors for these missing drives, but will restore the drives that exist on the target machine. 5 / 9
