Exception: Reloading Archived Data
21ScenarioReload in the test system
Data in a test environment can be reloadedat any time, since this does not affectoperational data (cannot result in businessinconsistencies)
ScenarioReload immediately afterarchiving
Restoring the database due to anerror (e.g. incorrect selection,incorrect customizing of residencetimes)
Reloading archived data back into the DB should beconsidered only in the following cases:
Reload function is not availablefor all archiving objects

Finding the Right Time
1A „healthy“ SystemData Archiving should not be seen as the lastresort for preventing total system collapseafter all other means have been exhausted.
2Early PlanningEnsure that the performance of yoursystems remains efficient.
3Interdisciplinary ProcessData Archiving requires a high degree of cooperation betweenuser and IT departments.

Detailed Data Archiving Statistics
Automatically collected statistics can be used toDemonstrate the use and need for data archivingBetter plan future archiving projectsRecognize resource bottlenecks early on
Statistics can beStoredDisplayed
Standard statistics logAnalyze statistics in Archive Administration (transaction SARA)Space information: Database space and disk spaceAmount: Number of data objects, structures, and delete jobsTime: Job duration
Rule of thumb: Compression factor of five – DB size vs. file sizeThe greater the number and the variation of archivingobjects used, the closer the factor is to five
