Cloud Backup & Disaster Recovery for Indian Enterprises
Cloud backup and disaster recovery is the discipline of keeping restorable copies of data and a tested way to run critical systems elsewhere when a site, region or account is lost. NTSPL audits existing backups, chooses the DR pattern each workload can afford, builds immutable vaults and cross-region recovery on AWS, Azure or Google Cloud, and proves it with timed drills.
Cloud Backup & Disaster Recovery at a Glance
Most Indian IT teams can show a green backup dashboard; far fewer can say how long it would take to bring back the core banking, billing or ERP stack after a ransomware event that also deleted the backup console. The gap shows up in RBI and SEBI inspections, in cyber-insurance questionnaires and in the first real outage. Typical findings: 20-35% of servers outside any policy, restore tests never timed, DR replicas in the same account as production, and recovery targets that nobody in the business signed.
This family covers the full life of recovery capability. Assessment pages decide what to protect and to which RPO and RTO. Pattern pages build pilot light, warm standby, active-active and cross-region designs. Protection pages harden backups against deletion and corruption. Operating pages turn all of it into runbooks, drills and a business continuity plan that leadership and auditors can sign.
Four Workstreams That Take Recovery from Assumed to Proven
Decide: assess backups and set recovery strategy
Two assessments answer different questions. The backup assessment audits what is actually protected, restorable and retained today. The DR assessment runs a business impact analysis, assigns recovery tiers and picks a DR pattern per service with its cost band. Business continuity alignment then connects those technical tiers to the BCP, crisis roles and regulator expectations.
Backup Assessment
Audit your current backup estate: unprotected workloads, untested restores, retention gaps and backup spend across AWS, Azure, Google Cloud and on-prem.
Disaster Recovery Assessment
Business impact analysis, RTO and RPO per business service, and a costed DR pattern choice from backup-restore to active-active for Indian firms.
Business Continuity Alignment
Connect DR tiers, runbooks and drills to your BCP: crisis roles, workarounds, supplier continuity, regulator notices and board reporting per ISO 22301.
Protect: backup design for data and databases
Policies, vaults, retention ladders and restore paths for VMs, file shares, object stores and managed databases. Database pages cover point-in-time recovery, log shipping and logical-corruption rollback. Immutable and protected backup adds vault locks, separate recovery accounts and multi-person approval so one stolen admin credential cannot erase every copy.
Cloud Backup Architecture
Design backup policies, vault topology, retention ladders and restore paths for AWS, Azure and Google Cloud workloads, tied to tags and recovery tiers.
Database Backup & Recovery
Point-in-time recovery, log backups, logical corruption rollback and fast large-database restores for PostgreSQL, MySQL, SQL Server and Oracle on cloud.
Immutable & Protected Backup
Vault locks, air-gapped copies, separate recovery identities, multi-person approval and clean-room restore so ransomware cannot erase your backups.
Recover: DR patterns from pilot light to active-active
Pilot light keeps only data replicated and infrastructure as code ready; warm standby runs a scaled-down live copy; active-active serves traffic from two sites at once. Cross-region recovery covers India region pairs, replication choices and DNS or global load balancer failover. Each pattern has a different RTO, RPO and monthly cost.
Pilot Light DR
Pilot light DR keeps databases replicated and compute dormant in a second region, recovering in 30 minutes to a few hours at a fraction of standby cost.
Warm Standby DR
Warm standby DR runs a scaled-down, always-on copy of your stack in a second region and scales up in 5-15 minutes, on AWS, Azure and Google Cloud.
Active Active Resilience
Active-active multi-region design with multi-writer data, idempotent APIs and regional cells, so losing a region means reduced capacity, not downtime.
Cross Region Recovery
Region pairs, data replication, keys, images, DNS failover and connectivity for DR between Mumbai, Hyderabad, Pune, Chennai and Delhi cloud regions.
Prove: runbooks and DR testing
Runbooks turn recovery into ordered, owned and automated steps with decision points and rollback. DR testing schedules tabletop, component and full failover drills, times every step against the RTO, and records evidence auditors accept. Findings feed back into design changes, so each drill shortens the next real recovery.
DR Runbooks
DR runbooks with decision points, owners, timed steps, automation and rollback, written as code for AWS, Azure and Google Cloud and kept current.
DR Testing
Tabletop, component, isolated and live failover DR drills, with every step timed against RTO and RPO and evidence that auditors and regulators accept.
Recovery Outcomes NTSPL Measures on Every Engagement
How Backup and DR Is Built on AWS, Azure and Google Cloud
On AWS, NTSPL builds with AWS Backup policies and Vault Lock, logically air-gapped vaults, AWS Elastic Disaster Recovery for server replication, Aurora Global Database and DynamoDB global tables for data, and Application Recovery Controller for controlled failover between Mumbai and Hyderabad. Drills use AWS Fault Injection Service and Resilience Hub assessments.
On Azure, the toolset is Azure Backup with immutable vaults and Resource Guard, Azure Site Recovery between Central India, South India and West India, SQL auto-failover groups, and Azure Business Continuity Center as the single protection view. Front Door or Traffic Manager handles failover routing, and Azure Chaos Studio supports controlled fault drills.
On Google Cloud, NTSPL uses Backup and DR Service with backup vaults that enforce minimum retention, Cloud SQL and AlloyDB cross-region replicas, Backup for GKE, and Cloud DNS routing policies or global load balancing for failover between Mumbai and Delhi. Infrastructure is kept in Terraform so a recovery project can be built on demand.

Cloud Backup & Disaster Recovery: Frequently Asked Questions
Where should a company start if it has backups but no DR plan?
Start with a backup assessment, then a DR assessment. The first tells you whether your existing copies can actually be restored and how long that takes; the second decides which systems need more than backup. Skipping the audit risks designing DR on top of backups that are incomplete or untested.
How much does cloud DR typically cost compared with a second data centre?
For most mid-size Indian estates, a pilot light or warm standby design on cloud costs 15-35% of what a dedicated secondary data centre with idle hardware and colocation fees would. The saving comes from paying for compute only during drills and real events, while storage and replication run continuously.
Do Indian regulators require DR to be in India?
Data localisation rules differ by sector. RBI requires payment system data to be stored in India, and CERT-In requires logs to be maintained within Indian jurisdiction for 180 days. With two AWS regions, four Azure regions and two Google Cloud regions in India, in-country DR is available on every major provider.
Is backup enough protection against ransomware?
Only if at least one copy is immutable and isolated from production credentials. Attackers routinely delete backup catalogues and snapshots before encrypting. NTSPL designs a locked or logically air-gapped copy, a separate recovery identity and a clean-room restore process so recovery does not reintroduce the infection.
How often should DR be tested?
Tier 1 systems should see at least one full failover drill a year and a component-level test each quarter; many regulated entities test every six months. Tabletop exercises with business owners should run at least twice a year, because people and contact lists change faster than infrastructure.
Can NTSPL protect workloads that stay on premises?
Yes. Many engagements use cloud as the recovery site for on-premises VMware, Hyper-V or physical servers, replicating with AWS Elastic Disaster Recovery, Azure Site Recovery or Google Backup and DR Service, while production remains in the customer's data centre.
