Establishing Storage-First Compliance and Recovery for Ayan Analytics on AWS

Solution Delivered

Infimatrix implemented a comprehensive Backup and Restore solution for Ayan Analytics that combined AWS-native storage capabilities with Veeam Backup & Replication to deliver a secure, automated, and regulation-ready backup environment. The solution addressed every stage of the backup lifecycle: data capture, immutability, storage tiering, automation, cross-region protection, monitoring, and restore validation. To ensure data immutability and long-term compliance, Amazon S3 was deployed with Object Lock in compliance mode, protecting backup data from overwrite or deletion. S3 Versioning was activated on all critical buckets, enabling rollback and integrity assurance. Backups were encrypted using SSE-KMS with customer-managed keys, and all access was governed through fine-grained IAM roles, S3 bucket policies, and AWS Config rules that validated enforcement of encryption, object lock, and lifecycle policies.

Veeam Backup & Replication was the primary orchestration layer for backups. Veeam policies were configured to automatically initiate daily backup jobs across Amazon EC2, Amazon RDS, and structured file outputs such as BOD/EOD transaction logs. Backup data was written directly to the Object Lock–enabled S3 buckets. Veeam’s tagging integration allowed automatic discovery and backup scheduling for newly provisioned workloads, enabling a zero-touch backup experience. Backup vault management and scheduling were completely automated, and backup verification was enabled to test job integrity after each run.

To support SEBI’s 7-year data retention mandate without incurring high storage costs, S3 Lifecycle Policies were used to automatically transition backup data across tiers. Active data remained in S3 Standard, after 90 days it moved to S3 Glacier Flexible Retrieval, and after 365 days to Glacier Deep Archive. This tiered structure helped Ayan reduce its long-term storage costs by over 40% while maintaining audit readiness and restoring integrity.

For disaster recovery and cross-regional fault tolerance, S3 Cross-Region Replication (CRR) was enabled for all critical backup buckets and Veeam-targeted data. Replication was configured between AWS Mumbai (ap-south-1) and Singapore (ap-southeast-1) to ensure data survivability in the event of a regional outage. Point-in-time recovery (PITR) was implemented for Amazon RDS using both Veeam and AWS-native snapshots, supporting rollback of structured financial data. These recovery points were integrated into regular test drills.Quarterly disaster recovery tests were performed using simulated failure scenarios to validate sub-30-minute RTOs. These drills included full environment recovery from Veeam snapshots and PITR for Amazon RDS, verifying data consistency, restore speed, and compliance adherence.

Recovery testing was conducted quarterly through simulated failure scenarios. These drills validated the ability to restore EC2 instances, database snapshots, and object-level data from S3. Recovery time metrics were captured and documented using Veeam’s console, with observed RTOs under 30 minutes and RPOs under one hour. Restore success was tracked through CloudWatch and Veeam logs, providing traceable evidence of SLA adherence.

Monitoring and compliance were built into every layer of the storage stack. AWS CloudTrail tracked all API interactions with backup and storage resources. AWS Config continuously evaluated compliance posture, checking for encryption, versioning, and lifecycle rule presence. CloudWatch Alarms and SNS notifications were used to detect failed backups, configuration drift, or missed recovery points. Additionally, Veeam’s backup console provided job-level dashboards, success/failure tracking, and SLA visibility for operational and compliance teams.

The architecture was built to scale elastically, with tag-based automation driving lifecycle transitions, backup scheduling, and policy assignment. As new workloads came online, Veeam automatically discovered tagged EC2 instances and RDS environments and applied the relevant backup policies without manual intervention. Backup snapshots were version-tracked, retention logic enforced centrally, and restore checkpoints auditable across both AWS and Veeam layers.

To ensure secure and scalable external access to compliance reports and application interfaces, Amazon CloudFront was used as the content distribution layer in front of the web and reporting applications. It provided low-latency access and reduced origin load, especially during audit periods and investor reporting cycles. AWS WAF was integrated with CloudFront to inspect all incoming requests and block potential threats or malformed traffic at the edge, helping Ayan enforce security policies before requests reached the internal infrastructure. These services, combined with encryption (TLS in transit, SSE-KMS at rest), IAM policies, and AWS Config validations, ensured that the storage environment remained secure, performant, and compliant from edge to archive.

This solution gave Ayan Analytics a secure, compliant, and fully automated backup environment with minimal manual overhead. It aligned with SEBI’s security, availability, and integrity standards and positioned the firm to recover confidently from failures, audits, or data corruption events — all while optimizing long-term storage spend.
