    Abstract: An improved information management system is described herein that provides on-demand or live mount access to virtual machine data in a secondary copy format. For example, instead of restoring all of the virtual machine data in the secondary copy format to a virtual disk that is then mounted to a virtual machine, the improved information management system can, in response to request to access virtual machine data in a secondary copy format, create a virtual disk having a universal network component (UNC) path and create a virtual machine configured to access data via the UNC path. Once created and booted, the administrator or user can attempt to access the desired virtual machine data via the virtual machine.

    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 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。

    Abstract: Expandable cache management dynamically manages cache storage for multiple network shares configured in a file server. Once a file is written to a directory or folder on a specially designated network share, such as one that is configured for “infinite backup,” an intermediary pre-backup copy of the file is created in an expandable cache in the file server that hosts the network share. On write operations, cache storage space can be dynamically expanded or freed up by pruning previously backed up data. This advantageously creates flexible storage caches in the file server for each network share, each cache managed independently of other like caches for other network shares on the same file server. On read operations, intermediary file storage in the expandable cache gives client computing devices speedy access to data targeted for backup, which is generally quicker than restoring files from backed up secondary copies.
