OADP features and plug-ins
OpenShift API for Data Protection (OADP) features provide options for backing up and restoring applications.
The default plug-ins enable Velero to integrate with certain cloud providers and to back up and restore OKD resources.
OADP features
OpenShift API for Data Protection (OADP) supports the following features:
Backup
You can back up all resources in your cluster or you can filter the resources by type, namespace, or label.
OADP backs up Kubernetes objects and internal images by saving them as an archive file on object storage. OADP backs up persistent volumes (PVs) by creating snapshots with the native cloud snapshot API or with the Container Storage Interface (CSI). For cloud providers that do not support snapshots, OADP backs up resources and PV data with Restic.
Restore
You can restore resources and PVs from a backup. You can restore all objects in a backup or filter the restored objects by namespace, PV, or label.
Schedule
You can schedule backups at specified intervals.
Hooks
You can use hooks to run commands in a container on a pod, for example, fsfreeze
to freeze a file system. You can configure a hook to run before or after a backup or restore. Restore hooks can run in an init container or in the application container.
OADP plug-ins
The OpenShift API for Data Protection (OADP) provides default Velero plug-ins that are integrated with storage providers to support backup and snapshot operations. You can create custom plug-ins based on the Velero plug-ins.
OADP also provides plug-ins for OKD resource backups, OpenShift Virtualization resource backups, and Container Storage Interface (CSI) snapshots.

Mandatory.
Virtual machine disks are backed up with CSI snapshots or Restic.
The
csi
plug-in uses the Velero CSI beta snapshot API.
