Unit 6: Archiving ADM100
• Improve response times or ensure good response times
• Reduce costs for database administration
• Reduce system downtime for software upgrades, recoveries, and
(offline) data backups
• Legal requirements and business requirements must be taken into
account here, such as:
– Country-specific retention rules
– Data must be available to auditors
– Potential reusability of data
Data must be archived in a way that means it can be called at any time for
queries. These queries could, for example, be from tax authorities. There
are legal data retention requirements in each country. Also, only data from
completed business processes can be archived.
With data archiving, data is archived independent of the hardware and
software release statuses (metadata is stored). In this way, it is still possible
to call archived data without any problems even after a system upgrade.
Cooperation Between the System Administration and
User Departments
You should begin planning the archiving of application data during the
implementation of SAP software. The volumeoftransactionandmaster
data can increase very quickly when live operation is first started.
The system administration’s aim is to keep the database as small as
possible; that is, to delete as many data objects as possible to reduce the
database load. The aim of user departments, on the other hand, is to be
able to access as many documents as possible online for queries, lists, and
reporting.
The process of data archiving is about finding a compromise between these
two positions that satisfies both sides. The long-term aim must certainly
be to maintain as constant as possible a volume of data in the database and
to archive data proactively instead of reactively.
At this point, you can briefly describe the different tasks of the system
administration on one hand and the user department on the other in an
archiving project. The SAP system administration is usually responsible
for database analysis, SAP ArchiveLink Customizing, setting up and
connecting archives, general archive Customizing, and configuring the
SAP system (background server, and so on). The IT department is, in
particular, also responsible for ensuring that the archived data is safely
retained for the required period of time. The user department, on the other
