> ## Database integrity

> Fathom Replication provides failure processing to help ensure database integrity. Database integrity is a major concern of all database users, and the need for database integrity is compounded because now two or more databases must remain identical. Fathom Replication achieves database integrity by performing synchronization. However, Fathom Replication is not a substitute for a comprehensive backup and recovery plan.

> When a source database is started, various operations are performed by the database manager to guarantee database resiliency. Some of the operations change the database. When a source database is started, the database changes must be replicated to any and all target databases. Fathom Replication achieves this by performing synchronization during startup. During the startup-synchronization process, all database activity that might have occurred during database startup is replicated to the target database.
