Abstract
A method and system for file transfer over a messaging infrastructure are provided. The method includes dividing a file into multiple portions. The method includes generating for a current portion of a file, except for the first portion in a file, a first hash summarizing the state of the file up to, but not including, the current portion and a second hash summarizing the state of the file up to and including the current portion. The method includes sending the first and second hashes with the file portion. The second hash may be used at a target for comparing to a first hash of a subsequent file portion, for example, by recreating the second hash from the current state of the received file on the target.
