32 Considerations Before Data Archiving Is the data still required? Yes Can the data be summarized? Yes Summarize data No No Yes Deactivate the creation of the data Can the data be archived? No Yes Data remains in the database Archive data! SAP AG 2003, SAP NetWeaver Data Archiving, Georg Fischer / 32

33 Customer Example Starting point Approx. 290 gigabyte DB size and approx. 15 gigabyte DB growth per month Aim Reduction of DB growth rate to: Reduce hardware costs Maintain stable system performance Response times and system administration Faster implementation of support packages and upgrade projects Local currency conversion Archiving 19 archiving objects from FI, CO, MM, SD, and HR Result (October 2000) >200 gigabyte archived SAP AG 2003, SAP NetWeaver Data Archiving, Georg Fischer / 33

34 Customer Example Allocated DB size 'Without' Archiving Initial Archiving DB growth: ~15 GB/month Reduction: ~60GB SAP AG 2003, SAP NetWeaver Data Archiving, Georg Fischer / 34 Expected size without Archiving Allocated DB content With regular archiving DB growth: ~7 GB/month
