Customer Profile
- Industry — BFSI (SEBI-registered stockbroker)
- Location — India
- Employees — 5,000+
- Challenge — Establish a cross-region data-availability setup by replicating Amazon EBS volumes (via snapshots) from the Mumbai region to the Hyderabad region.
Business Challenge
- No disaster recovery / business continuity capability for critical production workloads.
- Single-region deployment in Mumbai (ap-south-1) created regional outage risk.
- Regulatory requirement to maintain a DR copy in a separate geographic region.
- Manual, ad-hoc backup copies with no automated cross-region replication.
AWS Services Used
- Amazon EBS
- Amazon EC2
- AWS EBS Snapshots
- AWS Backup
- AWS KMS
- Amazon CloudWatch
Solution Design
- Production workloads run on Amazon EC2 with Amazon EBS volumes in the Mumbai (ap-south-1) region.
- AWS Backup runs scheduled backup plans that create point-in-time Amazon EBS snapshots of the production volumes.
- AWS Backup automatically copies the EBS snapshots cross-region from Mumbai (ap-south-1) to a backup vault in Hyderabad (ap-south-2).
- Backup retention and lifecycle policies are configured to meet RPO and compliance requirements, with older snapshots aged out automatically.
- All EBS snapshots and AWS Backup vaults are encrypted at rest using AWS KMS in both regions.
- Amazon CloudWatch monitors AWS Backup jobs and cross-region copy jobs and alerts on failures.
- Backup frequency and retention are configured to meet a 4-hour RPO and an 8-hour RTO.
Business Outcomes
- Established automated cross-region DR using AWS Backup with EBS snapshot replication from Mumbai to Hyderabad.
- Met defined recovery objectives: RPO of 4 hours and RTO of 8 hours.
- Centralized, policy-driven backup management with automated retention and lifecycle.
- Improved business continuity posture and regulatory compliance.
- Reduced regional outage risk with Hyderabad as the recovery region.
