EFFICIENT BACKUP OF VIRTUAL DATA

摘要

A method, article of manufacture, and apparatus for protecting data. In some embodiments, this includes taking a snapshot of a virtual machine, parsing the virtual machine to determine a header section and a file system, indexing the virtual machine based on the parsing, storing the index in a storage device, and storing the snapshot in a deduplicated data storage device.
