Enterprise Backup Modernization & Cyber Resilience for a Leading Private Sector Bank

425 TB	1.8 PB	4 PB + 425 TB	99.9999%
Existing backup estate planned for migration	3-year STR design capacity across DC + DR	3-year LTR object storage design capacity	Target backup success rate defined in SOW

IMPACT

Leading Private Sector Bank’s backup modernization program is designed to create a unified, secure and scalable data protection framework across Chennai DC, Mumbai DR and Mumbai NDR – supporting diverse enterprise workloads, multi-site recovery, cyber-resilience controls and long-term retention.

• Unified Data Protection: Centralized backup and recovery architecture spanning primary, disaster-recovery and near-DR environments.
• Cyber Resilience by Design: Immutable protection, air-gap capability, ransomware safeguards, encryption, access controls and threat-detection requirements embedded into the design.
• Large-Scale Modernization: Migration planning for a 425 TB existing backup estate into a modern object-storage-led retention architecture.
• Performance-Led Recovery: Defined recovery objectives include a 1 TB VM backup target of 20 minutes and restore target of 30 minutes.
• Enterprise Visibility: Executive, SOC, IT operations, SLA, KPI, compliance and health-check dashboards are included in the operating model.

MAJOR ISSUES

The transformation needed to address the complexity, security and governance demands of a banking-grade backup environment:

• Legacy Backup Modernization: 425 TB of existing backup data required a controlled migration path without compromising retention or data integrity.
• Highly Diverse Workloads: Protection was required across Solaris, Linux, Windows, Kubernetes, PCA, VMware and multiple enterprise database platforms.
• Ransomware & Cyber Risk: The target environment required immutability, air-gap protection, malware scanning, quarantine, MFA/RBAC and integrity validation.
• Complex Multi-Site Operations: Backup traffic, replication and recovery needed to operate consistently across DC, DR and NDR with network isolation.
• Regulatory & SLA Pressure: The SOW defines stringent backup windows, recovery objectives, reporting and RBI/SEBI-aligned security requirements.

FROM BACKUP TO CYBER RESILIENCE

A modern banking backup strategy must protect data, preserve recoverability, support compliance and remain operational even when production systems are under attack.

HIGHLIGHTS

PROPOSED SOLUTION

The solution architecture combines Commvault data protection capabilities with Hitachi Vantara infrastructure to support high availability, multi-site copies, short-term recovery, long-term retention and enterprise cyber resilience.

• High-Availability Control: Primary and standby CommServe environments synchronize through Live Sync for resilient policy, reporting and management.
• Multi-Site Protection: Short-term backup copies across DC and DR, with additional protected copies and long-term retention across the wider architecture.
• Storage & Network Efficiency: Source-side deduplication and high-speed connectivity design help reduce transfer and storage overhead.
• Agentless VM Protection: Virtual Server Agent capabilities support full-VM, disk and file-level recovery without agents on every guest VM.
• Application-Aware Backup: Protection scope includes physical servers, virtual machines, databases, file systems, Kubernetes and enterprise applications.
• Automation & Integration: Policy creation, VM discovery, scheduling, monitoring, ticketing and DR activities are designed for automation and integration.

USE CASES ADDRESSED

• Unified Backup and Recovery Across Location 1 (DC), Location 2 (DR) & Location 3 (NDR).
• Migration of the existing backup estate into the modernized data protection environment.
• Air-gapped, immutable and encrypted protection for ransomware resilience.
• Protection for physical, virtual, database, container and file workloads.
• Automated scheduled/manual backups, restores, monitoring, ticketing and DR drills.
• Integration with ServiceNow, SIEM, AD/Azure Entra and enterprise monitoring/security tools.

ARCHITECTURE AND DEPLOYMENT SCOPE

LOCATION 1 (DC)	LOCATION 2 (DR)	LOCATION 3 (NDR)
PRIMARY	RECOVERY	AIR-GAP
STR + HA CONTROL	STR + REPLICATION	PROTECTED COPY

LONG-TERM RETENTION / OBJECT STORAGE  |  IMMUTABLE + ENCRYPTED

• Three-Site Protection Model: Unified data protection across DC, DR and NDR.
• Short-Term Recovery: P1/P2/P3 workloads protected across active recovery tiers.
• Long-Term Retention: Extended retention requirements with object-storage-based design.
• Cyber-Resilient Layer: Immutability, retention lock, ransomware safeguards and malware controls.
• Encryption & Access: AES-256, SHA-256 integrity validation, MFA and RBAC requirements.
• Enterprise Integration: Designed to connect with ITSM, SIEM, identity and monitoring platforms.

KEY STRATEGIES

• Cyber Resilience First: Treat backup as part of the bank’s security and business-continuity strategy – not only as a storage function.
• Automation-Led IT Operations: Reduce manual effort through automated discovery, policy creation, scheduling, ticketing, monitoring and DR workflows.
• Operational Visibility: Provide role-specific dashboards for executives, SOC, operations, SLA/KPI and compliance stakeholders.
• SLA-Driven Operations: Measure backup success, completion time, recovery time, retention, restore success, encryption and utilization against defined KPIs.
• Scalable Architecture: Support data growth and new workloads without fundamentally redesigning the protection model.

BUSINESS TAKEAWAY

A modern backup platform is not simply another copy of data. It is a foundation for recoverability, cyber resilience, compliance and business continuity across a complex banking environment.
