A bulk update changes the wrong customer records. An Amazon RDS point-in-time restore can give your team a copy from before the change. The operational decision is whether to recover selected records from that copy or switch the application to a restored instance.
Choose and record the recovery point
Find the last known good time using audit logs or an application event, and record it with the time zone. Confirm it is inside the database’s earliest and latest restorable times. The Amazon RDS point-in-time restore guide explains how a restore creates a separate DB instance and how to find the recovery window. This guide concerns RDS DB instances. Confirm the appropriate process for your engine and deployment type.
Restore into an isolated environment
Use approved access controls and keep live workers from connecting to the restored database. Check its network access, parameter settings and credentials. AWS notes that storage can continue initialising after the instance becomes available. Time the point at which your representative queries and application checks actually work. A status of Available alone is an incomplete recovery measurement.
Decide what must return to production
Compare the affected records and their dependencies with the live database. For a limited correction, a reviewed repair may preserve valid transactions entered after the chosen recovery point. Test the repair with a representative copy and reconcile related records. For a wider failure, plan a controlled cutover and agree which later transactions need replay or manual reconciliation. Test the application’s new connection and ensure the team understands when writes must stop.
Record elapsed time, the oldest and latest records recovered, and outstanding exceptions. Assign ownership for securing and retiring the restored test instance. The backup restore testing guide gives a broader framework for recovery targets and acceptance checks.
ITZ’s backup and recovery service can help define the recovery scope and test how staff would restore operations. Describe the database and the kind of data change you need to recover from.
