If the virtual hard drive uses SCSI controller, you should provide appropriate drivers while

performing system restore to the virtual machine. For example, the widespread VMware

environment requires Buslogic or LSI logic drivers. Use drivers bundled with your virtual

machine software or download the latest drivers versions from the software manufacturer

website.

3.7.5 Limitations in using Acronis Universal Restore

1. The system recovered by Acronis Universal Restore may not start if the partition structure

in the image or the target disk partitioning does not coincide with that of the source disk. As

a result, the loader, restored from the image, will point to the wrong partition and the

system will not boot or will malfunction.

Such might be the case if you:

- image not the entire source disk, but only the selected partitions

Keep in mind, that the source disk may have a hidden maintenance partition created by the

computer vendor. Therefore, if you check each partition for backup instead of checking the

disk, this hidden partition will not be included into the image.

- restore not the entire source disk, but only the selected partitions. In some cases,

especially if your system resides on other than the first partition, this can confuse the loader

and prevent the restored system from startup.

To avoid the problem, we recommend that you image and restore the entire system disk.

2. The Acronis Universal Restore option does not work if the image contains dynamic disks

and volumes.

3. The Acronis Universal Restore option does not work if a computer is booted with Acronis

Startup Recovery Manager (using F11) or the backup image is located in Acronis Secure

Zone. This is because Acronis Startup Recovery Manager and Acronis Secure Zone are

primarily meant for instant data recovery on the same computer.

3.7.6 Getting Acronis Universal Restore

Acronis Universal Restore is an add-on to Acronis True Image Enterprise Server. It is

purchased separately and installed from a separate setup file.

3.8 Using dynamic disks and volumes

Acronis True Image Enterprise Server supports dynamic disks, i.e. disks, managed by

Windows Logical Disk Manager (LDM). You can create an image of one or more dynamic

volumes of any type (simple, spanned, stripped etc.) and restore it to a dynamic volume of

any type or MBR volume (partition) and vice versa, restore an MBR volume image to a

dynamic volume. In each case, the program stores and restores volume contents only. The

type or other properties of the target volume will not be changed.

However, the partition resize is possible when you restore a dynamic volume to a basic disk

partition.

If Acronis True Image Enterprise Server runs in rescue mode (for example, booted from

Bootable Rescue media), dynamic disks will not be accessible. Therefore, to be able to repair

a system partition, you must keep its image on a basic, network, or removable disk.
