Abstract
A system and method for maintaining a backup data base. An initial backup copy of a data base is made and stored separate from an active primary data base. Each time the primary data base is updated, audit information pertaining to the data base update is stored in non-volatile storage. A recovery processor continuously reads the audit information from the non-volatile storage and updates the backup data base accordingly, thereby maintaining a backup data base which is nearly up-to-date with the primary data base.
