Payroll Can't Go Down: Backups, Disaster Recovery & Data Residency in India
When attendance and payroll support thousands of field workers, resilience is an operating requirement—not an infrastructure footnote.

High availability is not disaster recovery
Running multiple application instances across availability zones protects against everyday hardware and service failures. Backups and point-in-time recovery cover many operational mistakes. Disaster recovery addresses rarer events that compromise an entire region or the integrity of the primary system.
A platform can be highly available inside one region and still lack a tested way to recover from regional failure, destructive corruption or ransomware.
Keep sensitive workforce data in India
Workforce systems contain identity, bank and salary information. A primary environment in Mumbai and a recovery environment in Hyderabad keep the designed posture within India while separating the two operating regions. Data should remain encrypted in transit and at rest.
Choose the recovery posture deliberately
Backup and restore has the lowest standby cost but can take hours and may lose data since the last successful backup. Warm standby keeps a smaller live copy in a second region and can target recovery in roughly 30–120 minutes with a 5–15 minute recovery point. Active-active aims for near-zero interruption but carries substantially greater cost and complexity.
These recovery objectives describe a designed target, not a guarantee. Cross-region disaster recovery is an optional add-on whose scope, testing and commercial terms should be agreed explicitly.
Promote the standby instead of rebuilding
A useful runbook detects the incident, gives a named authority the decision to declare a disaster, promotes the standby database, scales the standby application and switches users to the recovery region. Because the standby already runs the same application and configuration, the team restores service rather than constructing it during a crisis.
Ransomware needs immutable backups
Replication alone is not enough because it can copy destructive writes. Immutable backups should live under protected retention in a separate account so a compromised administrator cannot delete them or shorten their retention. Recovery then restores a clean point in time and uses the activity history to identify the last trustworthy state.
Recovery only counts when it is tested
Automated restore checks can run weekly, tabletop walkthroughs and runbook reviews quarterly, and non-production failover drills half-yearly. Each drill should record measured recovery time, measured data loss, gaps and named corrective actions.

Frequently asked
Is cross-region disaster recovery included by default?
Everyday availability can be part of the base platform. Cross-region recovery is an optional add-on selected and priced for the required posture.
Why use Hyderabad as the standby region?
It separates recovery from Mumbai while keeping the designed data-residency posture in India.
How do you prove disaster recovery works?
Run scheduled restore and failover drills, then compare measured recovery time and data loss with the agreed targets.
