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: 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. An 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 a virtual-machine-file-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: A data storage system receives a user instruction through a user interface to restore a specific virtual machine file from a block-level backup. The system accesses a file index which is created during the block-level backup by accessing the file allocation table of the underlying host system and associating the blocks with the file location information of the virtual machine files stored in the file allocation table. The system further creates a file level table based at least in part on the virtual machine file information stored in the file index, displays a listing of the virtual machine files from the file level table, and receives a user selected virtual machine file to restore.

Abstract: According to certain aspects, a system may include a data agent configured to: process a database file residing on a primary storage device(s) to identify a subset of data in the database file for archiving, the database file generated by a database application; and extract the subset of the data from the database file and store the subset of the data in an archive file on the primary storage device(s) as a plurality of blocks having a common size; and at least one secondary storage controller computer configured to, as part of a secondary copy operation in which the archive file is copied to a secondary storage device(s): copy the plurality of blocks to the secondary storage devices to create a secondary copy of the archive file; and create a table that provides a mapping between the copied plurality of blocks and corresponding locations in the secondary storage device(s).

Abstract: Systems and methods enable a virtual machine, including 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 moves data blocks from backup to a primary storage destination that becomes the virtual machine's primary data store after relocation completes. An enhanced data agent, operating in conjunction with an enhanced media agent in a storage management system, coordinates restoring the virtual machine and launching the relocation operation. The enhanced media agent pre-stages certain backed up data blocks based on predictive analysis pertaining to the virtual machine's operational profile. The enhanced media agent also pre-stages backed up data blocks for the relocation operation, based on the operation's relocation scheme. The media agent tracks read requests and maintains the contents of an associated read cache.

Abstract: A data storage system protects virtual machines using block-level backup operations and restores the data at a file level. The system accesses the virtual machine file information from the file allocation table of the host system underlying the virtualization layer. A file index associates this virtual machine file information with the related protected blocks in a secondary storage device during the block-level backup. Using the file index, the system can identify the specific blocks in the secondary storage device associated with a selected restore file. As a result, file level granularity for restore operations is possible for virtual machine data protected by block-level backup operations without restoring more than the selected file blocks from the block-level backup data.
