Why Disaster Recovery is Non-Negotiable for Indian Businesses
India faces unique disaster risks: monsoon flooding, power outages, earthquakes (especially in Maharashtra, Gujarat, and North India), and increasingly sophisticated cyberattacks including ransomware. Add to this the strict DR requirements from RBI, SEBI, IRDAI, and NHB for regulated entities, and disaster recovery planning becomes a compliance mandate — not just a best practice.
Understanding RTO vs RPO
Recovery Time Objective (RTO) is how long you can afford to be without a system after a disaster. If your ERP goes down, can you survive 4 hours? 4 minutes? Your RTO drives the technology choices and cost of your DR solution.
Recovery Point Objective (RPO) is how much data you can afford to lose. If your RPO is 1 hour, you must ensure backups are taken at least every hour. A 24-hour RPO means you could lose a full day’s transactions — acceptable for some systems, catastrophic for others.
DR Strategies (Tiered by RTO/RPO)
- Tier 1 – Hot Standby (RTO: minutes, RPO: seconds) — Active-active or active-passive clusters. Highest cost. For core banking, payment systems, and life-critical applications.
- Tier 2 – Warm Standby (RTO: 1-4 hours, RPO: 15 mins) — Veeam replication to a secondary site (Azure or colocation). VMs are pre-staged and can be powered on quickly. Ideal for most enterprise workloads.
- Tier 3 – Cold Standby (RTO: 4-24 hours, RPO: hours) — Backup-based recovery. Restore from Veeam backups to new or existing infrastructure. Lower cost, longer recovery. For non-critical systems.
RBI DR Requirements for BFSI in India
RBI mandates that scheduled commercial banks maintain a DR site at a minimum distance of 250 km from the primary data centre and achieve recovery within defined RTOs. Core banking systems typically require RTO of 2 hours. NBFCs and payment aggregators have similar obligations under respective RBI guidelines. Azure India’s two regions (Central India – Pune, South India – Chennai) are approximately 1,200 km apart — ideal for meeting RBI’s distance requirement.
DR Testing — The Most Overlooked Step
A DR plan that’s never tested is just a document. Untested DR fails 40% of the time in real disasters. Test your DR with: tabletop exercises (quarterly), component testing (monthly — verify individual backups), partial failover tests (semi-annually — failover non-critical systems), and full DR drill (annually — full failover and failback with stakeholders present).
Veeam’s SureBackup and SureReplica features automatically test recoverability of every backup — giving you zero-error verified recovery confirmation without manual testing overhead.
