SEBI’s modifications to guidelines concerning Business Continuity Plan (BCP) and Disaster Recovery (DR) systems for Market Infrastructure Institutions (MIIs), such as Stock Exchanges, Clearing Corporations, and Depositories
Near Site (NS) Requirement:
Stock Exchanges: Must have a Near Site (NS) in addition to a Disaster Recovery Site (DRS) to ensure near-zero data loss.
Clearing Corporations & Depositories: NS must ensure zero data loss.
Manpower at DRS: Expertise at the DRS must be equivalent to that at the Primary Data Center (PDC), enabling independent operations at short notice.
Recovery Point Objective (RPO):The RPO, which determines the maximum tolerable data loss, should be near zero. There should be a documented process for data reconciliation when resuming operations from DRS or other sites.
Solution Architecture:
Stock Exchanges: PDC, DRS, and NS must ensure high availability, fault tolerance, no single point of failure, near-zero data loss, and data integrity.
Clearing Corporations & Depositories: The same, but with a requirement for zero data loss.
Replication:
Stock Exchanges: Synchronous replication between PDC and NS for near-zero data loss; asynchronous replication between PDC and DRS.
Clearing Corporations & Depositories: Synchronous replication between PDC and NS for zero data loss; asynchronous between PDC and DRS.
