Apparatus, system, and method for virtual machine backup

An apparatus, system, and method are disclosed for a virtual machine backup. A name module establishes an administrative machine name for a virtual machine. A space module associates at least one administrative name space with the administrative machine name. A backup module backs up files belonging to the virtual machine using a backup proxy, wherein the files are segregated under the administrative machine name and are accessible using only a secure key belonging to the virtual machine and without using a backup proxy secure key. A mask module masks out pathname components for each backup file pathname so that the backup file pathname is equivalent to a virtual machine file pathname.
