Rational Synergy provides the following methods for backing up databases:
Determine which method is appropriate for your environment. You might back up some databases with one method, and others with another method. However, it is best to choose one method.
After you have chosen a backup method and have developed a backup plan, test and automate the plan. Remember to test the corresponding restore procedures of the backup method, as well.
The methods discussed here archive information from the metadata and file systems of the database. They do not back up work areas. Users with copy-based work areas must reconcile changes before the administrator runs the backup. If changes have not been reconciled, changes to work areas must be backed up separately.
