Roadmap for Performing a Bare Metal Restore on Linux
Machines
In AppAssure 5 you can perform a Bare Metal Restore (BMR) for a Linux machine,
including rollback of the system volume. When you restore a Linux machine, you will
roll back to the boot volume recovery point. BMR functionality is supported using the
command line aamount utility and from within the Core Console UI.
To perform a bare metal restore for Linux machines, perform the following tasks.
 Manage a Linux boot image. This Linux Live DVD boot ISO image is used to start
up the destination drive, from which you can access the Universal Recovery
Console to communicate with backups on the Core. See “Managing a Linux Boot
Image” on page 173.
 If you require physical media to start up the destination Linux machine, you will
need to transfer the ISO image to media. See “Transferring the Live DVD ISO
Image to Media” on page 174.
 In all cases, you will need to load the boot image into the destination server
and start the server from the boot image. See “Loading the Live DVD and Starting
the Target Machine” on page 174.
 Manage Partitions. You may need to create or mount partitions before
performing a BMR on a Linux machine. See“Managing Linux Partitions” on
page 175.
 The Linux system on which you are performing a BMR must have the same
partitions as the source volumes in the recovery point. You may need to create
additional partitions on the target system, if required. See “Creating Partitions
on the Destination Drive” on page 175.
 Mount partitions. If performing a BMR from the Core Console, you must first
mount partitions. See “Mounting Partitions from the Command Line” on page 177.
Steps to mount partitions are included in the process to perform a BMR from
the command line. See “Launching a Bare Metal Restore for a Linux Machine
using the Command Line” on page 179.
 Launch a Bare Metal Restore for Linux. Once the destination machine is started
from the Live DVD boot image, you can launch the BMR. The tasks required
depend on whether you will perform this from the AppAssure user interface or
from the command line using the aamount utility. See “Launching a Bare Metal
Restore for Linux” on page 177.
 If using the Core Console, you will need to initiate rollback from a recovery
point on the Core. See “Selecting a Recovery Point and Initiating Rollback for
BMR” on page 165.
 If using the Core Console, you will need to map the volumes from the UI. See
“Mapping Volumes for a Bare Metal Restore” on page 166.
 Optionally, if restoring from the command line, you can start the screen utility
to enhance your ability to scroll and see commands in the terminal console. For
more information, see “Starting the Screen Utility” on page 178.
 If using aamount, all tasks will be performed at the command line. For more
information, see “Launching a Bare Metal Restore for a Linux Machine using the
Command Line” on page 179.
