Can anyone tell me whether the Archive Information System (AIS) can be used to store all the archived files data? We were told in SAP Archiving class (BIT660) that you can purchase a third party storage system for ADK FIles. The SAP instructor also said you could purchase AIS and store all your archived ADK Files on AIS. Is that true? Where can I find information about storing all ADK FIles on AIS instead of buying a third party storage system.
