Performing A Rollback For A Linux Machine

A rollback is the process of restoring the volumes on a machine from recovery points. In AppAssure 5, you can perform
a rollback for volumes on your protected Linux machines using the command-line aamount utility.
CAUTION: Do not attempt to perform a rollback on the system or root (/) volume.
NOTE: Rollback functionality is supported for your protected Windows machines within the AppAssure 5 Core
Console. For more information, see
To perform a rollback for a volume on a Linux machine:
1. Run the AppAssure aamount utility as root, for example:
sudo aamount
2. At the AppAssure mount prompt, enter the following command to list the protected machines:
lm
3. When prompted, enter the IP address or hostname of your AppAssure Core server.
4. Enter the logon credentials, that is, the username and password, for this server.
A list is displayed showing the machines protected by this AppAssure server. It lists the agent machines found by
line item number, host/IP address, and an ID number for the machine (for example:
293cc667-44b4-48ab-91d8-44bc74252a4f).
5. Enter the following command to list the currently mounted recovery points for the specified machine:
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 is displayed 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 for rollback:
r [volume_recovery_point_ID_number] [path]
This command rolls back the volume image specified by the ID from the Core to the specified path The path for the
rollback 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, 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 agent machines, and you enter the lr command for number 2, and
you want to rollback the 23 recovery point volume b to the volume that was mounted to the directory /mnt/
data, the command is: r2 23 b /mnt/data.
Description
Specify a different agent machine to restore the recovery point to a custom agent.
Enter the user name and password to restore the recovery point to any machine that
booted in URC mode.
