First move
This control is evidenced by people and documents, not systems. Put the document under version control with an owner and review date, and log each review as a record with reviewer and date. Do not try to automate it.
Common gaps auditors find
- Alternate storage shares the same power, network or hazard zone as the primary site
- Equivalence assumed from a provider claim with no assessment
- Retrieval never tested, so the time to recover from that site is unknown
