/* Basic idea */
The main idea to backup a VM or a VM-Template is, to divide the task into three subtasks:
* Snapshot: Save the machines state (CPU, Memory and Disk)
* Merge: Merge the Disk-Image-Snapshot with the liveLive-imageImage
* Retain: Export the snapshot files
A more detailed and technical description for these three sub-processes can be found in the following sub-chapters.
