5.1.2 - The repository shall manage the number and location of copies of all digital objects.


SP uses an automated URI generation procedure, file naming procedure, and file system to manage the number and location of objects in a consistent manner. Each object has a unique, unambiguous URI and location in archival storage. This information is located in the preservation metadata. The TSM backup system has a database that associates tape backup copies with their originals in the Pillar storage array.

Please see the URI & File Naming Plan and Workflow Charts for more information. For reference, the Backup Plan is also available.
