Abstract
A backup agent issues to a virtual machine management service (VMMS) a request to export a virtual machine (VM). The VMMS generates a configuration file associated with the export that cannot be accessed by the backup agent because the file is encrypted. A full backup of the exported VM is performed. A first backup check point corresponding to the full backup is created. After the full backup, a second backup check point is created. The agent issues to the VMMS a request to export changes to the VM between the first and second backup check points. An incremental backup of the exported changes is performed and a backup components document is created. A synthetic full backup based on the incremental and full backups is created and restoration of the VM from the synthetic full backup is based on the information in the backup components document.
