Journaling combines the protection of forced writes (also known as synchronous writes) with better performance, and also supports the improved disaster recovery provided by journal archiving.

When enabled, journal archiving allows databases to recover from a complete loss of an InterBase server machine to within a few minutes of when the disaster occurred, or to a specific point in time.

This chapter defines key terms such as journal, journal file, and journal archive, and explains how to implement and use them with your database.

Note: Journaling is available in the Server Edition of InterBase, starting from version 2007. It is not available in the Desktop Edition.
