Security of Stored Data in SAP NetWeaver ILM
When storing archived data in the file system, you have read and write access to the file system with the technical system user of the SAP system. The system temporarily moves the archive files to the file system and then deletes them after forwarding them to the ILM store. The archive files in the file system and the ILM store, are stored not in plain text but in binarily text in an SAP-specific, compressed format.
A logical path define the storage location of the archived data in the file system. You need to specify this path in Customizing for the archiving object.

To guarantee the non-changeability of data and the protection from early deletion, the resources (archive files) and their higher level collections (hierarchy nodes of the store) are stored on an ILM-certified WebDAV server.

To manage the store hierarchies, the service that you use to manage ILM stores saves the metadata to the system database. Depending on which service you use, the storage location of the metadata is:
ILM Store Service |
Metadata Storage Location |
|---|---|
Storage and Retention Service (SRS) |
Database of the AS ABAP on which the SRS runs |
XML Data Archiving Service (XML DAS) |
Database of the AS Java on which
|
You can guarantee the security of the metadata with the standard function of the database you are using.

To ensure that the dataset you are managing in Retention Warehouse is still complete after the transfer from the legacy system, use the checksums function before and after the transfer and the ILM-compliant conversion of the data (archive files).
