Performing a bare metal restore for Linux machines
353
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 .
◦ To obtain the boot image for BMR, you must first determine which image you need and then download it from the
License Portal. See About the boot ISO image for Linux followed by Downloading a boot ISO image for Linux .
◦ If you require physical media to start up the destination Linux machine, you will need to transfer the ISO image to
media. See Saving the Live DVD ISO image to media .
◦ 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 .
◦ After you load the media, you must connect the Linux machine to the Rapid Recovery Core. See Connecting to the
BMR target from the Rapid Recovery Core .
• Manage Partitions. You may need to create or mount partitions before performing a BMR on a Linux machine. See
Managing Linux partitions .
◦ 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 .
◦ If you are performing a manual BMR, you must first mount partitions. See Mounting partitions from the command
line . 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 .
If you are using auto-partitioning for BMR within the Core Console, you do not need to mount
partitions. Rapid Recovery will restore the same partitions as those included in the recovery point(s)
being restored.
• 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 Rapid Recovery user interface or
from the command line using the local_mount utility. See Launching a bare metal restore for Linux .
◦ If using the Core Console, you will need to initiate a restore from a recovery point on the Core. See Selecting a
recovery point and initiating a BMR .
◦ If using the Core Console, you will need to map the volumes from the UI. See About disk mapping for a bare metal
restore .
◦ Optionally, if restoring from the command line, you can use the screen utility to enhance your ability to scroll and
see commands in the terminal console. This utility opens by default. If you close it, you can start it again. For more
information, see Starting the Screen utility .
◦ If using local_mount, 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 .
• Verifying a Bare Metal Restore. After starting the bare metal restore, you can verify and monitor your progress. See
Verifying the bare metal restore from the command line .
◦ You can monitor the progress of your restore. See Viewing the recovery progress .
◦ Once completed, you can start the restored server. See Starting a restored target server .
◦ Troubleshoot the BMR process. See Troubleshooting connections to the Universal Recovery Console and
Repairing boot problems .
