Journals
For a dynamic backup of your database, use journals in combination with checkpoints.
While checkpoints provide you with a snapshot of the database, journals keep track of all changes made to journaled tables after the last checkpoint.
When you are journaling a database, you should do the following:
• Take regular checkpoints of your database to minimize recovery time.
• Periodically verify that your journaling data is correct by auditing the database. For information, see
Audit Trails with Journals.
