A method, system and program for efficiently archiving and recovering a database is disclosed. The archiving process utilizes a reverse chronological order for the tape to facilitate efficient restoration of the database. The recovery processing utilizes a linked list to track record updates and avoid updating the same record with anything but the most current information.
