 Acronis Backup & Recovery 11.5 schedules tasks using the signature of the source hard disk.
If you recover the same disk signature, you don't need to re-create or edit the tasks created
previously.
 Some installed applications use disk signature for licensing and other purposes.
 This enables you to keep all the Windows Restore Points on the recovered disk.
 To recover VSS snapshots used by Windows Vista's "Previous Versions" feature.
 Keep existing
The program will leave the NT signature of the target hard disk untouched.
How the automatic mapping works
Acronis Backup & Recovery 11.5 automatically maps the disks or volumes to the target disks only if
the system bootability can be preserved. Otherwise, the automatic mapping is canceled and you
have to map the disks or volumes manually.
Also, you have to map the volumes manually if they are Linux logical volumes, or Linux software RAID
(MD devices). For more information on recovering logical volumes and MD devices, see Recovering
MD devices and logical volumes.
The automatic mapping is performed as follows.
1. If the disk or volume is recovered to its original location, the mapping process reproduces the
original disk/volume layout.
The original location for a disk or volume means exactly the same disk or volume that has been backed up.
A volume will not be considered original if its size, location or other physical parameters have been changed
after backup. Changing the volume letter or label does not prevent the software from recognizing the
volume.
2. If the disk or volume is recovered to a different location:
 When recovering disks: The software checks the target disks for size and volumes. A target
disk must contain no volumes and its size must be large enough to place the disk being
recovered. Not initialized target disks will be initialized automatically.
If the required disks cannot be found, you have to map the disks manually.
 When recovering volumes: The software checks the target disks for unallocated space.
If there is enough unallocated space, the volumes will be recovered "as is".
If unallocated space on the target disks is less than the size of the volumes being recovered,
the volumes will be proportionally shrunk (by decreasing their free space) in order to fit the
unallocated space. If the shrunk volumes still cannot fit the unallocated space, you have to
map the volumes manually.
