An overview of replication
What is being replicated?• Volume• File-based• Database-based
How it is being replicated?• Asynchronously• Synchronously• “Timed” push or
pull• Caching
Anatomy of a databaseTables of information
Index of tables
Transaction Log for repair in the event of failure
Cache that sits in RAM
Database backup
Restore from tape/disk after a crash
Asynchronous replication
Non-consistent operation
Fast recovery
Synchronous replication
Non-consistent operation
Transfer to secondary host
Volume and file-based replication
