    Abstract: Virtual machine (VM) proliferation may be reduced through the use of Virtual Server Agents (VSAs) assigned to a group of VM hosts that may determine the availability of a VM to perform a task. Tasks may be assigned to existing VMs instead of creating a new VM to perform the task. Furthermore, a VSA coordinator may determine a grouping of VMs or VM hosts based on one or more factors associated with the VMs or the VM hosts, such as VM type or geographical location of the VM hosts. The VSA coordinator may also assign one or more VSAs to facilitate managing the group of VM hosts. In some embodiments, the VSA coordinators may facilitate load balancing of VSAs during operation, such as during a backup operation, a restore operation, or any other operation between a primary storage system and a secondary storage system.

    Abstract translation: 可以通过使用分配给一组VM主机的虚拟服务器代理（VSA）来减少虚拟机（VM）的扩散，这些VM主机可能决定执行任务的可用性。 可以将任务分配给现有虚拟机，而不是创建新的VM来执行任务。 此外，VSA协调器可以基于与VM或VM主机相关联的一个或多个因素（例如VM主机的VM类型或地理位置）来确定VM或VM主机的分组。 VSA协调器还可以分配一个或多个VSA以便于管理VM主机组。 在一些实施例中，VSA协调器可以在操作期间（诸如在备份操作，恢复操作或主存储系统和辅助存储系统之间的任何其他操作）中促进VSA的负载平衡。

    Abstract: The data storage system according to certain aspects can manage the archiving of virtual machines to (and restoring of virtual machines from) secondary storage. The system can determine whether to archive virtual machines based on usage data or information. The usage information may include storage usage, CPU usage, memory usage, network usage, events defined by a virtual machine software or application, etc. The system may archive virtual machines that are determined to have a low level of utilization. For example, a virtual machine can be archived when its usage level falls below a threshold level. The system may create a virtual machine placeholder for an archived virtual machine, which may be a “light” or minimal version of the virtual machine that acts as if it is the actual virtual machine. By using a virtual machine placeholder, a virtual machine may appear to be active and selectable by the user.

    Abstract: The disclosed systems and methods enable a virtual machine, including any applications executing thereon, to quickly start executing and servicing users based on pre-staged data blocks supplied from a backup copy in secondary storage. Substantially concurrently with the ongoing execution of the virtual machine, a virtual-machine-file-relocation operation may move data blocks originating in the backup copy to a primary storage destination that becomes the virtual machine's primary data store after the relocation operation completes. An enhanced data agent, operating in conjunction with an enhanced media agent in a storage management system, coordinates restoring of the virtual machine and the launch of the relocation operation. The enhanced media agent may pre-stage certain backed up data blocks which may be needed to launch the virtual machine, based on predictive analysis pertaining to the virtual machine's operational profile. The enhanced media agent may also pre-stage backed up data blocks for the relocation operation, based on the operation's relocation scheme. Servicing read requests to the virtual machine may take priority over ongoing pre-staging of backed up data. Read requests may be tracked so that the media agent may properly maintain the contents of an associated read cache. Some embodiments of the illustrative storage management system may lack, or may simply not require, the relocation operation, and may operate in a “live mount” configuration.
