My company uses Ghost 11 to have multiple OS images available for pre-release software testing. We're seeing restoring a Windows Server 2012 partition (roughly 35 gig partition) to take roughly an hour. If we restore another OS (from XP through Win 8) over the Server 2012 partition, that also takes an hour. These images have no compression.
If we have a different OS on the same system, such as Win 7, and restore an image of that same OS over the top of it, it takes roughly 8 minutes (again, these are no-compression images.). Only when we're overwriting Win Server 2012 does it take an hour. The images files are of roughly the same size - the bitrate plummets during 2012 restore.
Is there a switch we need to set on Ghost that will speed this up? Does Win 2012 use a form of drive or data encryption that needs to be disabled?
The only references to this type of behavior I've been able to find is people pulling their ghost images from a network server, but we're doing local images only.
Our system setup is:
| NTFS OS partition | Tiny FAT32 Ghost partition | NTFS Images partition |
We boot from a DOS CD, run Ghost from the FAT partition, and load images stored on the images partition over the OS partition.
