ABSTRACT:
An example of a method for error tracking includes sending a data object to a first location. This example also includes determining if the data object was successfully stored at the first location, and if so, storing meta data corresponding with the data object, wherein the meta data includes first path information. This example of the method also includes sending the data object to a second location. This example further includes determining if the data object was successfully stored at the second location, and if so, adding second path information to the meta data corresponding with the data object, to update the meta data. Some examples of the invention may be called a data centric error tracking and problem analysis method (and system), because the error tracking is generally based on the path traveled by the data.
