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.

* 
NOTE: This utility is provided for convenience; use of the Screen utility is optional.

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.

1.
If the machine was booted from the Live DVD, then in the terminal window, type screen and press Enter.

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.

* 
NOTE: This component was formerly called aamount.

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

* 
NOTE: When performing this procedure, do not attempt to mount recovery points to the /tmp folder, which contains the rapidrecovery-vdisk (formerly aavdisk) files.

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.

1.
To run the Rapid Recovery local_mount utility as root, type the following command and then press Enter:
sudo local_mount
2.
To list the protected machines, type the following command and then press Enter:
lm
3.
When prompted, enter the connection information for the Rapid Recovery Core as described in the following table, pressing Enter after each required command:

Table 151. Rapid Recovery Core connection information

Text Box

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.

4.
To list the recovery points for the machine that you want to restore, type the list recovery points command using the following syntax and then press Enter:
lr <machine_line_item_number>
* 
NOTE: You can also enter the machine ID number in this command instead of the line item number.

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

◦
A line item number
◦
Date and time stamp
◦
A lettered list of volumes within the recovery point
◦
Location of the volume
◦
Size of the recovery point
◦
An ID number for the volume that includes a sequence number at the end, which identifies the recovery point
5.
To select the recovery point for a restore, enter the following command and then press Enter:
r <recovery_point_ID_number> <path>
* 
CAUTION: You must ensure that the system volume is not mounted.
* 
NOTE: If you started the machine from the Live DVD, then the system volume is not mounted.

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.
6.
When prompted to proceed, enter y for Yes and then press Enter.

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

* 
NOTE: If you receive an exception message, the details regarding that exception can be found in the local_mount.log file. The local_mount.log file is located in /var/log/apprecovery.
7.
Upon a successful restore, exit local_mount by typing exit and then press Enter.
8.
Your next step is to verify the restore. For more information, see .

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.
* 
CAUTION: To restore the system or root (/) partition or entire operating system, see Performing a bare metal restore for Linux machines.
1.
Run the Rapid Recovery local_mount utility as root, for example:
sudo local_mount
2.
At the Rapid Recovery mount prompt, enter the following command to list the protected machines.
lm
3.
When prompted, enter the IP address or hostname of your Rapid Recovery Core server.
4.
Enter the logon credentials, that is, the user name and password, for this server.

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).

5.
Enter the following command to list the currently mounted recovery points for the specified machine:
lr <machine_line_item_number>
* 
NOTE: Note that you can also enter the machine ID number in this command instead of the line item number.

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.

6.
Enter the following command to select a recovery point to restore:
r <volume_recovery_point_ID_number> <device path>

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.

◦
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, you would use the protected machine line number (from the lm output), followed by the recovery point line number and volume letter, followed by the path, such as, r <machine_line_item_number> <recovery_point_line_number> <volume_letter> <path>. In this command, <path> is the file descriptor for the actual volume.

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:

r2 23 b /dev/sda5
* 
NOTE: It is possible to restore to / if needed. If performing a Bare Metal Restore using a Live DVD, it is assumed you want to restore to a different machine. For more information, see Launching a bare metal restore for Linux.
7.
When prompted to proceed, enter y for Yes.

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.

1.
After you initiate the process restoring data from a recovery point, while the task is in process, you can view its progress from the Running Tasks drop-down menu on the Core Console.
2.
Optionally, you can view detailed information in the Events page. Fore more information about monitoring Rapid Recovery events, see Viewing tasks, alerts, and events.
