Disk Destination; Nt Signature - ACRONIS Backup & Recovery 10 Server for Windows User Manual

The new virtual machine will be configured automatically, the source machine configuration
being copied where possible. The configuration is displayed in the Virtual Machine Settings
(p. 147) section. Check the settings and make changes if necessary.
Then you proceed to the regular disk mapping procedure described below.
Existing virtual machine
Available when the Acronis Backup & Recovery 10 Agent for Hyper-V or Agent for ESX/ESXi is
installed.
On selecting this, you specify the virtualization server and the target virtual machine. Then
you proceed to the regular disk mapping procedure described below.
Please be aware that the target machine will be powered off automatically before the recovery. If you
prefer to power it off manually, modify the VM power management option.
Disk #:
Disk # (MODEL) (p. 145)
Select the destination disk for each of the source disks.
NT signature (p. 143)
Select the way the recovered disk's signature will be handled. The disk signature is used by
Windows and the Linux kernel version 2.6 and later.

Disk destination

To specify a destination disk:
1. Select a disk where you want the selected disk to recover to. The destination disk's space should
be at least the same size as the uncompressed image data.
2. Click OK.
All the data stored on the target disk will be replaced by the backed up data, so be careful and watch out for
non-backed-up data that you might need.

NT signature

When the MBR is selected along with the disk backup, you need to retain operating system
bootability on the target disk volume. The operating system must have the system volume
information (e.g. volume letter) matched with the disk NT signature, which is kept in the MBR disk
record. But two disks with the same NT signature cannot work properly under one operating system.
If there are two disks having the same NT signature and comprising of a system volume on a machine, at the
startup the operating system runs from the first disk, discovers the same signature on the second one,
automatically generates a new unique NT signature and assigns it to the second disk. As a result, all the volumes
on the second disk will lose their letters, all paths will be invalid on the disk, and programs won't find their files.
The operating system on that disk will be unbootable.
To retain system bootability on the target disk volume, choose one of the following:
•
Select automatically
A new NT signature will be created only if the existing one differs from the one in the backup.
Otherwise, the existing NT signature will be kept.
