A method for increasing the efficiency of copying data is disclosed. In one embodiment, such a method includes receiving a request to copy data from a first location to a second location. The method determines an original copy algorithm associated with the request and determines whether the original copy algorithm is the best copy algorithm available to copy the data.

In certain embodiments, this may be accomplished by looking in a prioritized list of copy algorithms and selecting a more efficient copy algorithm from the list. A corresponding system and computer program product are also disclosed.
