Generate new NT Signature or copy from image ?

Hi,

Anyone know what this does ? or any technical articles ?

Just doing a restore and this has appeared ?

Thanks,

Mark.

 

Just for some more info I am restoring the image back to another Hard drive as the last one broke ? This is a different Manufacturer's drive but the same size ?

 

Perhaps this helps.

Hi,

Thanks for the info ? Do you always restore the signature ?

For example if you restore an image to the same drive then I would agree however what about when the drive is replaced and you need to do a restore. Information in the manual and tech support is misleading ?

Also when you do a restore do you normally have to rejoin a domain ?

Thanks again,

 

Hello all,

Thank you for using Acronis Corporate Products http://www.acronis.com/enterprise/

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:

• Create new
The program will generate a new NT signature for the target hard disk drive.

• Recover from backup

The program will replace the NT signature of the target hard disk with one from the disk backup.
Recovering the disk signature may be desirable due to the following reasons:

o Acronis software creates scheduled 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.
o Some installed applications use disk signature for licensing and other purposes
o Enables to keep all the Windows Restore Points on the recovered disk.
o to recover VSS snapshots used by Windows Vista's "Previous Versions" feature

• Keep existing

The program will leave the existing NT signature of the target hard disk as is.

Thank you.
