Abstract
An embodiment of the invention provides a method to extract selected information from an image file selectively without requiring the user to restore, on the destination storage server, the image file which has the data for a file system. The selected information can be, for example, contents of a file, contents of a directory, other information from the image file. The selected information can be selectively extracted by reading the blocks of the file from the WAFL data structures that has been stored in the image file. An index file is generated and this index file tracks the location of VBNs (virtual block numbers) in an image file so that the user can easily obtain the selected information from disk blocks that are identified by these VBNs.
