Help: Create image

You can create images from a partition or a whole drive of your client in this dialog. This image can be used to install clients. Select your preferred Image format, the Image transfer type and the Image compression. You have to make additional designations under "Image source" for some image formats e.g. the partition or drive that should be stored in the image.

At "Image format" select the desired format, at "Image transfer type" the network transfer type and at "Image compression" the kind of compression. At "Image source", select the partition or hard disk that you would like to use. Choose a name for the image and enter it at "Image name". Click on "Create image" afterwards.

You can access the overview about all created image files at "Server settings" → "Manage image files", where it is also possible to delete image files which are no longer needed.

If you would like to use the image file which you created here for the installation of a client, please select "Imaging" as client distribution during client "Setup".

Caution

The client will reboot immediately after clicking on "Create image" and before it begins to create the image! Data that has not been saved before will be lost. Please ensure that the client will be booted via network or another m23 client boot medium..

Hint for image files

The files are stored in the directory /m23/data+scripts/clientImages in different types and with distinct compressions. The file names are always created after the following scheme: <Image name><Size of the extracted image in bytes><Image format><Compression>

Image format is one of the following values:

• Partclone: For a partition whose file system is supported, only the used sectors will be saved, else the whole disk.

• dd: Saves the whole data of a partition or harddisk.

For the compression the following is valid:

• (no extension): The image file will be stored with no compression.
• gz: The image will be compressed with gzip.
• bz2: It will be compressed with bzip2 that compresses better mostly.

Hint for the Transfer port

You have to enter a network port that can be used on client and server side and is not blocked (e.g. firewall) for the Image transfer type. If you want to create images from multiple clients concurrently you have to choose different port numbers.
