Use the -restore mode command to retrieve an image from a specified location and restore it to a device.
You can restore an image of a device by using either the imaging maintenance mode prompt or by using the ZENworks Imaging Engine menu. For step-by-step instructions, see Manually Taking an Image of a Device. You can also use the Restore mode command to restore an image from a partition on a local hard disk. For step-by-step instructions, see Setting Up Disconnected Imaging Operations.
Normally, if the image to be restored is a base image (one created previously by the ZENworks Imaging Engine), all existing partitions except the ZENworks partition and Dell or Compaq configuration partitions are removed from all local hard disks before the new image is restored. When the image is restored, the sizes of the original partitions from which the image was taken are preserved, if possible. If there is insufficient space, the last partition is shrunk to fit, unless this would result in data loss, in which case the ZENworks Imaging Engine denies the requested operation. If there is extra space left after all partitions in the image have been restored to their original sizes, that space is left unpartitioned.
If the image to be restored is an add-on image, or if it’s a base image and you specify the apartition:ppartition parameter, none of the existing physical partitions are removed. Instead, the appropriate partitions are merely updated with the files from the image, overwriting any existing file of the same name and location.
The syntax of this mode depends on whether you will retrieve the image from a local device or from an imaging (proxy) server, as explained in the subsections below:
NOTE:When you perform a partition-based restore with Windows 7 or a later version, you need to restore the Windows system partition as well. For an example on how the restore is performed with the Tuxera NTFS driver, see Prerequisites for taking and restoring an image partition-wise.
Use the -restore -local mode command to retrieve an image from a local device and restore it to the device. For more information, see Setting Up Disconnected Imaging Operations.
To use the Help mode:
IMPORTANT:When you restore an image locally, using the Tuxera driver, use the following command to mount the partition on which the image is stored if the partition is NTFS:
# mount -t tntfs /dev/sdXn mount_dir
In this command, sdX is the device node and n stands for the partition number in the device.
To display the ZENworks Imaging Engine menu, enter:
img
Click Imaging > Restore Image.
This displays the Restore Image Wizard.
In the wizard, select Local, then click Next.
The Restore Local Image Wizard is displayed.
Fill in the fields:
Path to Image Archive: Click Browse to select the image file, or specify its full path and filename, including the .zmg filename extension.
File Set: The number of the image file set to be restored. Valid values are 1 through 10. File set 1 defaults. For information on file sets, see Section A.0, File Sets and Image Numbers.
Options: Specify any advanced options. For more information, see Table E-6.
Click Next to restore the image.
The ZENworks Imaging Engine Menu displays a progress bar while restoring image.
If the imaging process was successful, click OK in the Information dialog box, then click Close to return to a blank ZENworks Imaging Engine Menu display.
If the imaging process was unsuccessful, determine and resolve the issue, then repeat these steps.
Using the imaging maintenance mode prompt, the following example explains the syntax and available parameters that you can use with the “restore from local” (-restorel) mode command:
img -restore -local local_filepath/filename.zmg [‑part=partition_number] [‑s=file_set] [‑ap=advanced_options]
where the [...] brackets indicate optional commands.
You can abbreviate -restore -local as: -r -local, -restorel, or -rl.
For more information, see:
Table E-6 Restore Local Commands and Parameters
|
Parameter |
Specifies |
|---|---|
|
-restorel [‑part=partition_number] |
The partition number (as displayed by img dump) of the local partition to retrieve the image from. It must be a primary partition. This partition is not changed by the imaging operation. |
|
local_filepath/filename.zmg |
The filename of the image to retrieve, including the .zmg extension (case-sensitive) and the complete path from the root of the local partition. |
|
‑s=fileset |
The number of the image file set to be restored. Valid values are 1 through 10. For information on creating file sets of an image, see Creating, Installing, and Restoring Standard Images. If you omit this parameter, file set 1 is used. |
|
‑ap=partition:partition |
A mapping between a partition in the image archive (apartition) and a target physical partition on the local machine (ppartition). Use this parameter to selectively restore a specific part of the image to a specific local partition. IMPORTANT:If you use this parameter, none of the existing local partitions are removed, and only the target local partition is updated. The update process does not remove any existing files; however, any existing files of the same names are overwritten. If you want to remove all existing files from the target partition before updating it, first use the Partition Operations Mode to delete and recreate the partition. If you choose to restore the base image, you need to delete and recreate the target partition before restoring the image because your system might be left in an inconsistent state if the Selective Partition Image restoration fails. For apartition, use the partition number displayed for the source partition in the Image Explorer (zmgexp) utility. For ppartition, use the partition number displayed by img dump for the target partition. The target partition must be a partition of a supported file system. You can repeat this parameter as needed to request multiple selective restorations in a single operation. In doing so, you can apply multiple parts of the image to a single local partition, but you can’t apply the same part of an image to multiple local partitions in a single operation. |
Table E-7 Restore Local Examples
|
Example |
Explanation |
|---|---|
|
img -restorel /myimages/myimage.zmg ‑part=8 |
Removes all existing local partitions except the one in slot 8, retrieves the image from myimages/myimage.zmg in slot 8, and restores the partitions and contents of that image on the available local writable devices (assuming there is sufficient local space and that slot 8 contains a partition). |
|
img -restorel /myimages/myimage.zmg |
Removes all existing local partitions, retrieves the image from myimages/myimage.zmg in the ZENworks partition, and restores the partitions and contents of that image on the available local writable devices (assuming there is sufficient space). |
|
img -restorel /myimages/myimage.zmg ‑s=2 |
Removes all existing local partitions, retrieves the image from myimages/myimage.zmg in the ZENworks partition, and restores the partitions and contents of file set 2 of that image on the available local writable devices (assuming there is sufficient space). |

‑ap=partition:partition |
A mapping between a partition in the image archive (apartition) and a target physical partition on the local machine (ppartition). Use this parameter to selectively restore a specific part of the image to a specific local partition. IMPORTANT:If you use this parameter, none of the existing local partitions are removed, and only the target local partition is updated. The update process does not remove any existing files or overwrite any existing files of the same names if they are newer. If you want to remove all existing files from the target partition before updating it, first use the Partition Operations Mode to delete and re-create the partition. If you choose to restore the base image, you need to delete and recreate the target partition before restoring the image because your system might be left in an inconsistent state if the Selective Partition Image restoration fails. For apartition, use the partition number displayed for the source partition in the Image Explorer (zmgexp) utility.

Table E-9 Restore Proxy Mode Examples
|
Example |
Explanation |
|---|---|
|
img ‑restorep subdir1/myimage.zmg |
Removes all existing local partitions, retrieves the image from subdir1/myimage.zmg on the Imaging Server, and restores the partitions and contents of that image on the available local writable devices (assuming there is sufficient local space). |
|
img ‑restorep subdir1/myimage.zmg ‑s=2 |
Removes all existing local partitions, retrieves the image from subdir1/myimage.zmg on the Imaging Server, and restores the partitions and contents of file set 2 of that image on the available local writable devices (assuming there is sufficient local space). |
|
img ‑restorep subdir1/myimage.zmg ‑ap=a2:p1 |
Retrieves the image from subdir1/myimage.zmg on the Imaging Server, updates local partition 1 with the data from partition 2 of that image, and leaves the other local partitions unchanged (assuming there is sufficient space in local partition 1). |
|
img -rp image.zmg -ap=a3:p1 a4:p2 |
Retrieves image.zmg from server and updates local partition 1 with data from partition 3 and updates local partition 2 with data from partition 4 in the image. |
NOTE:In ZENworks, you only need to provide the image filename (the .zmg file) because the images are stored in a fixed location. For example, if you saved the image file in the default location, enter:
img -rp myimagefile.zmg
Because you can organize your images under the \images directory by adding subdirectories, the additional path where you created the image file should be provided. For example:
img -rp /windows/vista/myimagefile.zmg
