For buyers contracting authority
Reach for 72251000 when the purpose is continuity and recovery: a standby environment, replication, and a contracted promise to bring systems and data back within a set window. The deliverable is the failover capability and the tested plan that proves it, not the everyday running of the live system.
The boundary that trips contracting authorities is archiving and storage. Computer archiving (72252000) and Data storage services (72317000) keep copies of data; disaster recovery is the orchestrated service that uses those copies to restore live operations after an incident. If the contract's main output is a retained or stored copy, it sits with those codes; if it is the recovery and resumption of service, it sits here.
Watch the bundling pattern in the history above: several awards wrap disaster recovery inside a wider ICT managed-services or data-centre deal. When recovery is one line in a larger managed contract, set the primary CPV code by the dominant scope and use this code only where continuity and recovery genuinely lead. Where the deliverable is the data-centre space and facility itself rather than the recovery service, Computer facilities management (72514000) is the closer fit.
