Method to spoof data formats from image backups

摘要

A system and method for efficiently accessing large data storage subsystems with a different file format than a format used by running applications. A backup server is coupled to a data storage medium, and is configured to store data on the data storage medium according to a first file format. A client is coupled to the backup server and is configured to convey memory access requests for data stored in the data storage medium. The client is unable to decipher the first file format. A filter driver in the backup server is coupled to intercept the requests from the client. The filter driver is configured to decipher the first file format; spoof the existence of one or more spoofed files that do not exist on the data storage medium, wherein each of the one or more spoofed files corresponds to data stored on the data storage medium; and present the spoofed files to the client.
