Remap Amazon EKS namespaces on restore with AWS Backup resource modifiers

This article explains how to use AWS Backup resource modifiers to remap Amazon EKS namespaces during restore operations, allowing teams to restore namespaces to new locations on the same cluster.

• Resource modifiers are YAML files with rules that patch Kubernetes objects before creation during restore
• Two rules enable namespace remapping: one renames the Namespace object, another moves all objects within it
• Rules use match conditions and JSON Patch operations to select and modify objects
• Supports namespace-level restores to same or different clusters without modifying original recovery points
• Provides equivalent functionality to Velero's namespace-mappings flag natively in AWS Backup
• Can also scale deployments, update container images, modify ConfigMaps, and add labels at restore time

AWS Backup resource modifiers enable flexible namespace remapping and object patching for EKS restores, with no additional charges beyond standard AWS Backup pricing.
