For detailed instructions on how to recover logical volumes, see Recovering MD devices and logical
volumes (p. 264).
You do not need to create the volume structure if it already exists on the machine (such is the case
when some data on the volume was lost, but no hard disks were replaced).
How to select logical volumes to back up
Logical volumes appear at the end of the list of volumes available for backup. Basic volumes included
in logical volumes are also shown in the list with None in the Type column. If you select to back up
such partitions, the program will image it sector-by-sector. Normally it is not required. To back up all
available disks, specify all logical volumes plus basic volumes not belonging to them.
A logical volume is a GPT (GUID partition table) partition. Logical volumes are displayed under
Dynamic & GPT Volumes
.
Here is an example of a volumes list obtained with the command:
trueimagecmd --list
The GUI displays a similar table.

The system has three physical disks (Disk 1, Disk 2, and Disk 3). Two logical volumes, DYN1 and DYN2,
are arranged across basic volumes 1-2 and 2-1. Disk 3 includes Acronis Secure Zone which is not
normally backed up.
To back up the logical volume DYN1, select the volume DYN1.
To back up all three hard disks, select the volumes 1-1, 3-1, DYN1 and DYN2.
If you select Disk 2, volume 1-2 or volume 2-1, the program will create a raw (sector-by-sector)
backup.
To back up the logical DYN1 volume by using the command-line interface, run the following
command (here, the name of the backup is assumed to be /home/backup.tib):
trueimagecmd --partition:dyn1 --filename:/home/backup.tib --create
