Abstract:
The present invention relates to a system and method for preserving and identifying recency information for data stored in multiple mirrored memory locations in a redundant data storage mechanism. The inventive approach builds upon the benefits presented by redundant storage by appending an indication of storage recency to stored data, thereby enabling a future read operation to identify a degree of recency for data stored in each of a plurality of mirrored sites. The read operation will generally return only the most recently stored data found among the plurality of mirrored locations.
