Embodiment Construction

[0022]Systems and methods are described herein to protect virtual machine data at a block level and restore the protected data at a file level. Further examples of systems and methods for 1) processing of blocks during virtual machine backup; 2) selecting specific virtual machine files to restore from the block-level backup using a user interface; and 3) restoring selected virtual machine files from the block-level backup are described below with respect to FIGS. 2-5.

[0023]Moreover, it will be appreciated that data generated by information management systems such as those that will now be described with respect to FIGS. 1A-1E can be protected as well. And, as will be described, the componentry for implementing secondary data operations can be incorporated into such systems.

Information Management System Overview

[0024]With the increasing importance of protecting and leveraging data, organizations simply cannot afford to take the risk of losing critical data. Moreover, runaway data gro...

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.
