Recreating LVM structures and restoring data
SysBack provides the ability to do the following operations:
Restore data only.
Recreate LVM structures only.

Recreate only the volume group LVM structures.
Restore one or more individual file systems.
Recreate only the LVM structure of one or more file systems.
Restore one or more individual logical volumes.
