In Rapid Recovery, you can perform a Bare Metal Restore (BMR) for a protected Linux machine, including a restore of the system volume. BMR functionality is supported for Linux using the Restore Machine Wizard from the Core Console, and also using the command line local_mount
utility.
|
Caution: Rapid Recovery supports ext2 partition types only if the kernel is version 3.10 and above. If using an earlier kernel, convert any ext2 partitions to ext3, ext4, or XFS before you begin protecting and backing up the machine. |
|
Caution: When you boot a restored Linux machine for the first time after a BMR, Rapid Recovery Core first attempts to capture an incremental snapshot of the restored machine. If incremental capture is not possible due to the amount of data and the state of the machine, then Rapid Recovery Core captures a base image of the restored machine. This process takes more time than taking an incremental snapshot. For more information about base images and incremental snapshots, see Understanding protection schedules. |
To perform a bare metal restore for Linux machines, perform the following tasks.
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 being restored.
When performing a BMR, the destination drive onto which you will be restoring data must have the same partitions as in the recovery point you are restoring. You may need to create partitions to meet this requirement.
You can launch the restore from the command line using the local_mount utility, or you can launch the restore from the Rapid Recovery Core Console. If restoring using the user interface, you must first mount the partitions.
Managing Linux partitions is a step in Performing a bare metal restore for Linux machines.
You can perform the following tasks:
Often, when performing a BMR, the destination drive is a new volume that may consist of a single partition. The drive on the destination machine must have the same partition table as in the recovery point, including the size of the volumes. If the destination drive does not contain the same partitions, you must create them before performing the bare metal restore. Use the fdisk utility to create partitions on the destination drive equal to the partitions on the source drive.
After creating partitions on a new volume on the destination drive to perform bare metal restore, if you are not using auto partition, you must format the partitions before they can be mounted. If this situation applies to you, format partitions in ext3, ext4, or XFS formats.
For all other scenarios, you do not need to format partitions.
