International ClassG06F 017/30AbstractA method of automatically synchronizing a database with a backup database. The method automatically detects whether the backup database has fallen out of sync with the primary database which it mirrors. In response, a resynchronization process is automatically initiated in which the starting point for reading a redo log of the primary database is automatically determined and in which the backup database is automatically synchronized with the primary dataset.Field of SearchConcurrency (e.g., lock management in shared database)Distributed or remote access DATABASE SCHEMA OR DATA STRUCTURE FILE OR DATABASE MAINTENANCE Coherency (e.g., same view to multiple users) Recoverability Version management Archiving or backup File allocation Garbage collection Of memory or peripheral subsystem Redundant stored data accessed (e.g., duplicated data, error correction coded data, or other parity-type data) | |
