Starting the Screen utility

Included on the Live DVD is Screen, a utility which is available when you boot from the Live DVD into the Universal Recovery Console. Screen allows users to manage multiple shells simultaneously over a single Secure Shell (SSH) session or console window. This allows you to perform one task in a terminal window (such as verify mounted volumes) and, while that is running, open or switch to another shell instance to perform another task (such as to run the local_mount utility).

The Screen utility also has its own scroll-back buffer, which enables you to scroll the screen to view larger amounts of data, such as a list of recovery points.

The screen utility starts on the machine booted with the Live DVD by default. However, if you have closed this application, you must start the Screen utility from the Live DVD using the procedure below.

The Screen utility starts.

Launching a bare metal restore for a Linux machine using the command line

Once the Live DVD ISO image is accessible on the machine on which you want to perform a BMR, and the number and size of volumes matches between the target machine and the recovery point you want to restore to bare metal, then you can launch a restore from the command line using the local_mount utility.

If you want to perform a BMR using the Rapid Recovery Core Console UI, see Selecting a recovery point and initiating a BMR.

This task is a step in Performing a bare metal restore for Linux machines. It is part of the process for Launching a bare metal restore for a Linux machine using the command line.

Complete the steps in this procedure to select a recovery point on the Core to roll back to the physical or virtual BMR target machine.

Description

Required

Rapid Recovery Core IP address or hostname

The IP address or hostname of the Rapid Recovery Core.

Yes

Domain

The domain of the Rapid Recovery Core. This is optional.

No

User

The user name for an administrative user on the Core

Yes

Password

The password used to connect the administrative user to the Core.

Yes

A list displays showing the machines protected by the Rapid Recovery Core. It lists the machines found by line item number, the host display name or IP address, and an ID number for the machine.

A list displays the base and incremental recovery points for that machine. This list includes:

This command rolls back the volume image specified by the ID from the Core to the specified path. The path for the restore is the path for the device file descriptor and is not the directory to which it is mounted.

NOTE: You can also specify a line number in the command instead of the recovery point ID number to identify the recovery point. In that case, use the agent/machine line number (from the lm output), followed by the recovery point line number and volume letter (from the lettered list of volumes within the recovery point), followed by the path. For example:

r <machine_line_item_number> <base_image_recovery_point_line_number> <volume_letter> <path>

For example, type:

r 1 24 a /dev/sda1

In this command, <path> is the file descriptor for the actual volume.

After the restore begins, a series of messages will display that notify you of the restore completion status.

Restoring volumes for a Linux machine using the command line

In Rapid Recovery, you can restore volumes on your protected Linux machines using the command line local_mount utility.

NOTE: This process was previously referred to as Rollback. When performing this procedure, do not attempt to mount recovery points to the /tmp folder, which contains the rapidrecovery-vdisk (formerly aavdisk) files. Restoring volumes is also supported for your protected machines within the Rapid Recovery Core Console. See About restoring volumes from a recovery point for more information.
1.
Run the Rapid Recovery local_mount utility as root, for example:
2.
At the Rapid Recovery mount prompt, enter the following command to list the protected machines.

A list displays showing the machines protected by this Rapid Recovery server. It lists the protected machines found by line item number, host/IP address, and an ID number for the machine (for example: 7d658e5f-fa08-4600-95f0-5f486bc1b6a4#de0896fd-571a-4cc5-aeed-264d2c3c72f4#f377e145-dd4d-3ac3-5b15-37ce8f4913ba:2).

A list displays that shows the base and incremental recovery points for that machine. This list includes a line item number, date/timestamp, location of volume, size of recovery point, and an ID number for the volume that includes a sequence number at the end (for example,
”293cc667-44b4-48ab-91d8-44bc74252a4f:2”), which identifies the recovery point.

This command restores the volume image specified by the ID from the Core to the specified path. The path for the restore is the path for the device file descriptor, not the directory to which it is mounted.

For example, if the lm output lists three protected machines, and you enter the lr command for protected machine number 2, and you want to restore the 23 recovery point volume b to the volume that was mounted to the directory /dev/sda5, the command would be:

Once the restore proceeds, a series of messages will display to notify you of the status.

8.
Upon a successful restore, the local_mount utility will automatically mount and re-attach the kernel module to the restored volume if the target was previously protected and mounted. If not, you will need to mount the restored volume to the local disk and then should verify that the files are restored (for example, you can use the sudo mount command and then the ls command.)

Viewing the recovery progress

Complete the steps in this procedure to view the progress of restoring data from a recovery point (including bare metal restore) initiated from the Rapid Recovery Core Console.
