This document addresses the use of Ghost with Windows dynamic disks.
Symantec Ghost solution suite 3.x can clone basic disks, and dynamic disks that have simple volumes or mirrored volumes with some limitations.
To clone a basic disk
"Basic disk" is the term used in Windows to indicate that the disk is not a dynamic disk. That is, a basic disk does not include simple, mirrored, spanned, striped, or RAID-5 volumes. To clone a basic disk, run Ghost as usual.
To clone a dynamic disk
The best way to use Ghost to clone a dynamic disk is to perform a single partition-to-image cloning operation and not a disk-to-image cloning operation. To clone the entire disk, perform a partition-to-image operation and select all partitions on the source disk.
Ghost supports creating a partition image of a dynamic disk for both simple volumes and mirrored volumes and restoring that partition to a basic disk. Ghost does not support restoring a partition to a dynamic disk .
To clone a simple or mirrored volume, run Ghost normally. Ghost will detect the simple and mirrored volumes and will save the contents of the volume as a non-dynamic partition. After restoring the image to a basic disk, use the Windows Disk Management MMC utility to convert the partition to a simple or mirrored volume.
Note: Because Ghost cannot restore a partition image to a dynamic disk, you cannot use this process to convert a dynamic disk to a basic disk. If you want to restore a partition image to a dynamic disk, you must first convert the disk to a basic disk.
Because you can select all partitions on the source disk when performing a partition-to-image cloning operation, a disk-to-image clone is necessary only in unusual circumstances, and is only applicable for backup purposes. To access the dynamic disk on the restored disk, the image must be restored to a drive with exactly the same geometry. In practice, this means the image can only be restored back to the same disk.
Use a disk-to-image operation only as a last resort. Note that the process is considerably slower than a partition-to-image process, and that the resulting image file will usually be much larger.
To perform a disk-to-image cloning operation on a dynamic disk, run Ghost with the -IA switch on the Ghost command line, such as
Ghost supports creating a disk image of a dynamic disk only when using the -IA switch on the Ghost command line.
Ghost supports cloning a partition from a dynamic disk to a basic disk for both simple volumes and mirrored volumes. Ghost does not support cloning a partition to a dynamic disk.
After cloning simple volume or mirrored volume to a basic disk, use the Windows Disk Management MMC utility to convert the destination partition to a simple or mirrored volume.
