OpenShift API for Data Protection (OADP) is the official OpenShift operator for backup and disaster recovery of applications.

Think of it as:

“Velero, but fully integrated and supported inside OpenShift”

What OADP actually is

OADP is an OpenShift-native solution that:

• Uses Velero under the hood
• Adds OpenShift-specific integration and support
• Provides a simpler, supported way to:
  • Back up apps
  • Restore apps
  • Protect persistent data

What OADP does

1. Application backups

• Namespaces
• Deployments, services, routes
• ConfigMaps, Secrets

2. Persistent volume protection

• CSI snapshots (preferred)
• File-level backups (Restic)

3. Restore workloads

• Full namespace restore
• Selective restore (specific resources)

4. Scheduled backups

• Cron-based automated backups

Key components

DataProtectionApplication (core object)

Defines:

• Backup storage (S3, etc.)
• Snapshot locations
• Plugins

BackupStorageLocation

Where backups are stored (e.g., S3 bucket)

VolumeSnapshotLocation

Where PV snapshots are stored

Backup / Restore / Schedule

Same concepts as Velero:

• Backup
• Restore
• Schedule

OADP vs Velero

👉 In OpenShift, always prefer OADP

What OADP does NOT do

❌ Does NOT back up etcd
❌ Does NOT restore full cluster (alone)
❌ Does NOT replace control-plane backup

You still need:

• etcd backups for cluster recovery

Typical usage

• Backup application namespaces
• Migrate apps between clusters
• Restore after accidental deletion
• Disaster recovery (app-level)

Simple example

kind: Schedule
spec:
  schedule: "0 2 * * *"
  template:
    includedNamespaces:
      - my-app

This runs a daily backup of your app

Real-world pattern

Production setup:

• OADP → app backups (hourly/daily)
• etcd → cluster backup (daily)
• Storage snapshots → data durability

Final takeaway

• OADP = OpenShift-native backup solution
• Built on Velero
• Handles apps + data, not cluster brain
