simple/spanned, striped, mirrored, RAID 0+1, RAID-5) will not change. The target volume size has

to be enough to accommodate the backup content.

Recovery to disk group unallocated space

When recovering a dynamic volume to disk group unallocated space, the software preserves the

volume's original type and size. If the disk group configuration does not allow for the original

volume type, the volume will be recovered as a simple or spanned volume. If this volume does

not fit the unallocated space, the volume will be resized by decreasing its free space.

Examples of when the disk group configuration does not allow the original type of the volume

Example 1. The group contains fewer disks than is required for the dynamic volume. Assume you

are going to recover an 80 GB RAID-5 volume that had resided on three disks, to a disk group

consisting of two disks. The total size of unallocated space is 100 GB: 40 GB on the first disk and

60 GB on the second. The RAID-5 volume will be recovered as a spanned volume across two

disks.

Example 2. Unallocated space distribution does not allow recovery of certain types of dynamic

volumes. Assume you are going to recover a 30 GB striped volume to a disk group consisting of

two disks. The total size of unallocated space is 50 GB: 10 GB on the first disk and 40 GB on the

second. The striped volume will be recovered to the second disk as simple.

Recovery to a disk that has not been initialized

In this case, the target disk will be automatically initialized to the MBR partitioning style. The

dynamic volumes will be recovered as basic ones. If the volumes cannot fit into unallocated

space, they will be proportionally resized (by decreasing their free space).

The table below demonstrates the resulting volume types depending on the backed-up source and

the recovery target.

Moving and resizing volumes during recovery

You can manually resize the resulting basic volume during recovery, or change the volume's

location on the disk. A resulting dynamic volume cannot be moved or resized manually.

Preparing disk groups and volumes

Before recovering dynamic volumes to bare metal you should create a disk group on the target

hardware.

You also might need to create or increase unallocated space on an existing disk group. This can be

done by deleting volumes or converting basic disks to dynamic.

You might want to change the target volume type (basic, simple/spanned, striped, mirrored, RAID

0+1, RAID 5). This can be done by deleting the target volume and creating a new volume on the

resulting unallocated space.
