Journaling is generally the most attractive approach to recovery from integrity problems. It allows management of recovery using logical rather than physical constructs, including suppression of updates based on time and/or source and preservation of application-level logical transactions. Backward journal recovery is generally the fastest means of repair. The cost of journaling is the added load it imposes on normal operation to make and store the journal files. For more information on journaling, refer to the "GT.M Journaling" chapter.
