Abstract
A method and apparatus that include a hashing and retrieval module that receives an indicator of a portion of a file to access, generates a hash value of a local copy of the portion and generates a request for a remote copy of the portion of the file, the request including the hash value. A verification and response module receives the request for a portion of a server copy of a data file, the request including a first hashing value. The verification and response module retrieves the portion from a server storage device, generates a second hashing value from the portion, compares the first hash value and the second hash value and returns the portion of the file in response to a failed comparison of the first hash value and second hash value.
