Benefits
� SAP AG 2001, mySAP Technology Data Archiving,G. Fischer 6
The Rising Significance of Data
�The top concern for 90% of all IT managers:“Managing data and information overflow intelligently”(Survey by CSC Ploenzke AG, 2000)
�“Globally, data storage is becoming a major branch of industry and the central focus of information technology”(Dataquest, GartnerGroup Research Note: Storage will dominate server spending)
� Relative hardware investment� 1998: 57% servers, 43% storage� 2002: 20% servers, 80% storage
� SAP AG 2001, mySAP Technology Data Archiving,G. Fischer 7
What Does Data Storage Cost ?
�
„Hard disks are inexpensive! If I need more database space, I’ll add another disk to my storage system.“(Customer statement)

The Distribution of Storage Costs
�According to a study by the Giga Information Group, hard disk costs represent less than a quarter of storage costs.

Customer Experiences
�German and American customers report storage costs (without personnel costs) of US$ 4,000 - 15,000 per gigabyte in a productive database.
�German customers report outsourcing storage costs of DM 1,000 per month and per gigabyte.

Positioning
�Data archiving for a “healthy” system� data archiving should not be seen as the last chance to prevent system
collapse after all possible hardware upgrades have been exhausted
�Bring data archiving into the planning stage� maintain R/3 System performance
�Data archiving is an interdisciplinary process� data archiving requires a high degree of cooperation between user
departments and the IT department
� SAP AG 2001, mySAP Technology Data Archiving,G. Fischer 25
Find the Right Time
�Experiences from customer projects
�Why should Data Archiving not be postponed?� The project gets more complex the bigger the database has grown� The archiving programs need more resources� Longer recovery time in case of disaster� The maintenance windows for „data hygiene tasks“ might become
insufficient� Increased down time when installing higher software releases� Several archiving objects can be used soon after going live� Slower system response time makes all online users less efficient
