Moving and resizing volumes during recovery
You can manually resize the resulting basic volume during recovery, or change the volume's
location on the disk. A resulting dynamic volume cannot be moved or resized manually.
Preparing disk groups and volumes
Before recovering dynamic volumes to bare metal you should create a disk group on the target
hardware.
You also might need to create or increase unallocated space on an existing disk group. This can be
done by deleting volumes or converting basic disks to dynamic.
You might want to change the target volume type (basic, simple/spanned, striped, mirrored, RAID
0+1, RAID 5). This can be done by deleting the target volume and creating a new volume on the
resulting unallocated space.
Acronis Backup includes a handy disk management utility which enables you to perform the above
operations both under the operating system and on bare metal. To find out more about Acronis Disk
Director Lite, see the Disk management (p. 271) section.
3.7.2 Backup and recovery of logical volumes and MD devices
(Linux)
This section explains how you would back up and recover volumes managed by Linux Logical Volume
Manager (LVM), called logical volumes; and multiple-disk (MD) devices, called Linux Software RAID.
To learn more about LVM please visit http://tldp.org/HOWTO/LVM-HOWTO/ or

3.7.2.1 Backing up logical volumes
Acronis Backup Agent for Linux can access, back up, and recover logical volumes when running in
Linux starting with 2.6.x kernel or under Linux-based bootable media.
Backup
In Acronis Backup GUI, logical volumes appear under Dynamic volumes at the end of the list of
volumes available for backup. If you select logical volumes for backup, the logical volume structure
will be saved to the backup along with the volume contents. This structure can be automatically
recreated when you recover these volumes under a Linux-based bootable media.
To back up all available disks, specify all logical volumes plus basic volumes not belonging to them.
This is the default choice when you open the Create backup plan page.
Basic volumes included in logical volumes are shown in the list with None in the File system column.
If you select such volumes, the program will back them up sector-by-sector. Normally this is not
required.
Recovery
When recovering logical volumes, you have two options:
Recovering volume contents only. The type or other properties of the target volume will not
change.
This option is available both in the operating system and under bootable media.
