Conventional archive and retrieval systems inadequately identify the archival data with sufficient granularity to associate data items with retrieval performance, and do not define a recourse following loss of archived data. A method for file archiving, identification, and failure recourse facilitates successive disposition by generating an authenticated receipt of files transferred for storage via an authentication instrument that is verifiable towards both the data stored and a corresponding agreement. The authenticated receipt provides nonrepudiation assurances about the content of the file and the contractual terms under which the file was stored via an authenticating signature of the archive storage server which associates the file content with the contractual terms. The nonrepudiation assurances allow verification of the content of the archived file through a checksum or hash, and the authenticated receipt further indicates the terms of the contractual agreement for recourse by the client depositor in the event of loss of the file.
