    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: 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.

    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 translation: 根据某些方面的数据存储系统可以管理将虚拟机归档到二次存储器（并从其恢复虚拟机）。 系统可以根据使用数据或信息确定是否归档虚拟机。 使用信息可以包括存储使用，CPU使用，存储器使用，网络使用，由虚拟机软件或应用程序定义的事件等。系统可以归档被确定为具有低的利用水平的虚拟机。 例如，当虚拟机的使用级别低于阈值级别时，可以归档虚拟机。 该系统可以为归档的虚拟机创建一个虚拟机占位符，该虚拟机可以是虚拟机的“轻”或最小版本，该虚拟机的作用就像实际的虚拟机一样。 通过使用虚拟机占位符，虚拟机可能看起来是由用户激活和选择的。

    Abstract translation: 所公开的系统和方法使得虚拟机（包括其上执行的任何应用）能够基于在辅助存储器中的备份副本提供的预先分级的数据块快速开始执行和维护用户。 与虚拟机的持续执行大致同时，虚拟机文件重定位操作可以将在备份副本中发起的数据块移动到在重定位操作完成之后成为虚拟机的主数据存储的主存储目的地。 增强的数据代理，与存储管理系统中的增强型媒体代理一起运行，协调虚拟机的恢复和启动重定位操作。 基于与虚拟机的操作简档相关的预测分析，增强型媒体代理可以预先启动可能需要启动虚拟机的某些备份的数据块。 增强媒体代理还可以基于操作的重定位方案来预备用于重定位操作的备份数据块。 对虚拟机的读取请求的服务可能优先于备份数据的正在进行的预分配。 可以跟踪读取请求，使得媒体代理可以适当地维护相关读取高速缓存的内容。 说明性存储管理系统的一些实施例可能缺乏重新定位操作，或可能简单地不需要重新定位操作，并且可以以“实时安装”配置操作。
