Cloud Disaster Recovery India — BC DR for Businesses 2026

Cloud Disaster Recovery India — BC DR for Businesses 2026

Business Continuity and Disaster Recovery (BC/DR) planning answers two critical questions: If our systems go down, how quickly can we recover? And how much data can we afford to lose? For Indian businesses — particularly those in regulated industries — the answer is increasingly: within minutes, and almost nothing. Cloud-based DR makes this achievable at a fraction of the cost of traditional DR infrastructure.

#

Why Indian Businesses Need DR

Hardware Failure
On-premise servers fail. RAID can protect against a single disk, but motherboard failure, power supply failure, or data centre power outage takes everything down. Without DR, recovery from a server purchase and re-install can take days.

Power and Infrastructure
Indian power supply is still unreliable in many areas — even with UPS, extended outages or UPS failure causes downtime. Delhi, Mumbai, and Chennai all have intermittent grid issues.

Ransomware
Ransomware attacks on Indian businesses increased 300% from 2021 to 2024. If backup is on the same network as the infected system, the backup is also encrypted — leaving no recovery option.

Regulatory Requirements
- RBI requires NBFCs to have BCP/DR plans with documented RTO/RPO
- ISO 27001 requires DR testing annually
- SEBI requires regulated entities to maintain operational resilience

Key DR Concepts

RTO (Recovery Time Objective)
How long can your business be down before serious damage occurs?
- Banking NBFC: RTO of 4 hours means transaction system is down 4 hours — significant revenue and reputation impact
- E-commerce: RTO of 2 hours during a sale event = millions lost
- Most Indian businesses: RTO of 4-24 hours is acceptable for non-critical operations

RPO (Recovery Point Objective)
How much data can you afford to lose? If your backup is nightly and a failure occurs at 5 PM, you lose the entire day's transactions.
- Financial services: RPO of 0 (zero data loss) for transaction data
- Most businesses: RPO of 1-4 hours is acceptable (maximum 4 hours of transactions lost)

Traditional DR Cost
Maintaining a secondary data centre or co-location DR site: Rs. 5-20 lakh/month for most mid-size companies. Plus hardware, maintenance, and DR team.

Cloud DR Cost
Cloud DR can achieve similar RTO/RPO at Rs. 15,000-50,000/month — 90% cost reduction.

Cloud DR Options

Backup and Restore (Lowest Cost)
- Backups taken daily/hourly to cloud (S3, Azure Blob)
- In case of disaster: restore backup to cloud instances
- RTO: 4-24 hours (depends on data volume and instance provisioning time)
- RPO: 1 hour (if hourly backups)
- Cost: Rs. 5,000-15,000/month
- Best for: non-critical systems, small businesses

Pilot Light
- Core components always running in cloud (database replication ongoing)
- Compute: minimal — scaled up only during disaster
- RTO: 1-4 hours (time to scale up compute)
- RPO: 15-30 minutes (near-real-time database replication)
- Cost: Rs. 15,000-40,000/month
- Best for: mid-criticality systems, most Indian businesses

Warm Standby
- Fully functional scaled-down version always running in cloud
- In disaster: scale up to production capacity, switch DNS
- RTO: 15-60 minutes
- RPO: 5-15 minutes
- Cost: Rs. 30,000-80,000/month
- Best for: NBFCs, e-commerce, healthcare — where extended downtime is very costly

Hot Standby / Multi-Region
- Identical production environment running continuously in secondary region
- Traffic routed to secondary region immediately on primary failure
- RTO: seconds to minutes
- RPO: near-zero
- Cost: Rs. 1,00,000+/month
- Best for: banks, trading platforms, mission-critical systems

MICS Cloud DR Implementation

Assessment
- Application inventory: criticality and DR tier for each application
- RTO/RPO requirements: defined with business stakeholders
- Current state: existing backup and recovery mechanisms
- DR gap: what needs to be built

Implementation on AWS
- AWS Backup: centralised backup for EC2, RDS, DynamoDB, EFS
- AWS Site Recovery (ASR): replication of on-premise servers to AWS
- RDS Read Replica: cross-region database replication
- Route 53 health checks: automatic DNS failover
- Lambda runbook: automated failover sequence

Implementation on Azure
- Azure Site Recovery: on-premise to Azure replication
- Azure Backup: VM and database backups
- Geo-redundant storage: automatic cross-region data replication
- Traffic Manager: DNS-based failover to secondary region

DR Testing (Mandatory)
- Annual DR drill: simulate a disaster and recover to DR environment
- Validate RTO/RPO: time the actual recovery process
- Documentation: test results for regulatory compliance (RBI, ISO 27001)
- Lessons learned: what was slower than expected, what failed

RBI DR Requirements for NBFCs
- BCP/DR policy: Board-approved document
- RTO/RPO: defined per system criticality
- Annual DR test: evidence of test and findings
- DR infrastructure: in India (data residency)
- Vendor documentation: cloud provider's DR capabilities documented for RBI inspection
