摘要： A host server hosting one or more virtual machines can back up host volumes and the one or more virtual machines installed thereon in an application-consistent manner. In one implementation, a host-level requestor instructs a host-level writer to identify which virtual machines qualify for application-consistent backups. The host-level requestor then instructs the host-level writer to initiate virtual machine backups through guest-level requesters in each appropriately-configured virtual machine, wherein the virtual machines create application-consistent backups within the virtual machine volumes. The host-level requester then initiates snapshots of the server volumes on the host-level. The virtual machine-level snapshots can thus be retrieved from within the host-level snapshots of the server volumes.

摘要： A method and system for backing up and restoring data of production servers. A mapping that maps volumes of production servers to volumes of a data protection server is maintained on the data protection server. When volumes of the data protection server are backed up, the mapping may be stored on the archive media together with the data of the volumes. Later, during a restore, the mapping is read from the archive media. The mapping allows the data to be restored to the data protection server or directly to the production servers.

摘要： Physical (or prior virtual) machine volumes can be converted to virtual machines at a virtual machine host while the physical machines are running. In one implementation, a volume shadow copy service can be used to create an application (and/or file system)-consistent snapshot of one or more physical machine volumes while the one or more volumes are running. The snapshot data can then be transferred to a mounted virtual hard disk file (dynamic or fixed) at a virtual machine host. Operational information (e.g., boot record, system registry, drivers, devices, configuration preferences, etc.) associated with the virtual hard disk file and the operating system(s) within the virtual machine can then be modified as appropriate to ensure that the corresponding virtual machine is bootable and functional at the virtual machine host. The virtual hard disk file can then be un-mounted, and used as a new virtual machine.

摘要： Methods and systems for scanning a virtual machine image. The virtual machine image may be stored as a collection of one or more virtual hard disk files. The virtual machine image may be stored by taking the virtual machine off-line or may be stored by taking a checkpoint of the virtual machine while the virtual machine is on-line. The virtual machine image is rendered to file-system data. Rendering the virtual machine image to file-system data may comprise mounting the virtual machine image's virtual hard disk drives. An anti-malware engine is invoked to scan the exposed file-system data, and data indicative of the scanning may be stored.

摘要： Migration mechanisms are disclosed herein that smartly transfer data among virtual machines, minimizing the down time of migration of such machines but maximizing the consistent state of data stored thereon. Specifically, data can be classified into three types: low volatility data (such as hard disk data), high volatility data (such a random access memory data), and immutable data (such as read only data). This data can be migrated from a source virtual machine to a target virtual machine by sending the immutable data along with the low volatility data first—before the source virtual machine has stopped itself for the migration process. Then, after the source virtual machine has stopped, high volatility data and (again) low volatility data can be sent from the source to the target. In this latter case, only differences between the low volatility data may be sent (or alternatively, new low volatility data may be sent).
摘要翻译：本文公开了移动机制，其在虚拟机之间智能地传送数据，使得这些机器的迁移停机时间最小化，但是最大化其上存储的数据的一致状态。具体来说，数据可以分为低挥发性数据（例如硬盘数据），高挥发性数据（诸如随机存取存储器数据）和不可变数据（诸如只读数据）三种类型。通过在源虚拟机已停止自身以进行迁移过程之前首先发送不可变数据以及低挥发性数据，可以将该数据从源虚拟机迁移到目标虚拟机。然后，在源虚拟机停止之后，可以从源向目标发送高波动性数据和（再次）低波动数据。在后一种情况下，仅可以发送低波动性数据之间的差异（或者可以发送新的低挥发性数据）。

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.
