摘要：A virtual machine may be discovered through a directory service or via an agent that is installed on the host operating system that is running the virtual machine. If the agent is installed on the virtual machine, the agent monitors changes to a set of protected volumes on the virtual machine. If the agent is installed on the host, the agent monitors changes to the protected volumes, which may contain one or more virtual servers on the host. Periodically, these changes from the host or the virtual server are sent to a data protection server. The data protection server updates its replicas of protected volumes with the sent changes. Versions of files on a data protection server corresponding to a volume of a virtual server may be restored to the virtual machine, to another machine, or may be viewed from the data protection server.

主权项：1. A method comprising: discovering a plurality of host machines via a network; connecting a first machine to a host machine of the plurality of host machines via the network and installing an agent on the host machine of the plurality of the host machines, the agent being configured to discover, by querying a directory service, one or more virtual machines hosted by the host machine of the plurality of host machines and communicate the discovered virtual machines to the first machine, the virtual machines associated with storage volumes; instantiating replicas of the storage volumes based on configuration data discovered by the agent and sent to the first machine by the agent; receiving, by the first machine from the agent, changes to the storage volumes associated with the discovered virtual machines, saving the changes in a file associated with the discovered virtual machines, and storing the changes in one or more of the replicas, the changes having been monitored by the agent; receiving information indicative of a request to restore a virtual machine from a corresponding replica that corresponds to the virtual machine associated with the request; sending data associated with the corresponding replica to the agent; and causing the agent to restore the requested virtual machine by way of the sent data.
