SYSTEM AND METHOD FOR PROVIDING A MULTI-TIERED HIERARCHICAL TRANSIENT MESSAGE STORE ACCESSED USING MULTIPLY HASHED UNIQUE FILENAMES

A system and method for providing a multi-tiered hierarchical transient message store accessed using multiply hashed unique filenames is described. A hierarchical message store is maintained. The hierarchical message store is logically structured with a plurality of storage nodes. Each storage node is dependently linked to one of a plurality of index nodes. Each index node is dependently linked to a root node. An incoming message is intercepted at a network domain boundary and assigning a unique filename. An index hash of the unique filename, corresponding to one such index node, and a storage hash of the unique filename, corresponding to one such storage node, are generated. The message is stored in the hierarchical message store at the one such index node and the one such storage node.
