Content Management Service
Archive files created by SAP Data Archiving can be stored on tertiary storage media, such as WORMs, magnetic-optical disks, and tapes using the Content Management Service (CMS). This can be done manually or automatically.
From Release 4.6C, the Content Management Service replaces the SAP ArchiveLink in the Data Archiving context.
Hierarchical Storage Management Systems (HSM Systems)
Archive files can also be transferred to an HSM system simply by storing them in the file system of the HSM system. For storage, the HSM system can also use tertiary storage media, such as MO-disks.
