Business continuity and disaster recovery standards mandated for market infrastructure institutions, requiring zero data loss and rigorous DR testing. SEBI mandates enhanced BCP and DR obligations for Market Infrastructure Institutions requiring a Disaster Recovery Site and, where applicable, a Near Site to ensure zero data loss and independent live operations. MIIs must maintain one-to-one configuration parity between PDC and DRS/NS, ensure high availability and no single point of failure, implement synchronous replication to NS and appropriate replication to DRS, meet defined Recovery Time and Recovery Point Objectives, conduct realistic and unannounced DR drills and live trading sessions, board-approve a comprehensive BCP-DR policy, and submit the revised policy to SEBI.
