Data Recovery Service overview
The Data Recovery Service (DRS) is a microservice in CDP Private Cloud Data Services that allows you to back up and restore Kubernetes namespaces and resources on both Embedded Container Service (ECS) and OpenShift Container Platform (OCP). You can backup and restore namespaces for Control Plane and other supported services. The "Backup and Restore Manager" in the CDP Private Cloud Data Services Management Console, and the CDP CLI options for the respective services leverage the DRS capabilities to run the backup and restore events (jobs).
Cloudera recommends that you create a backup of your Kubernetes namespace before a maintenance activity, before you upgrade, or in general, as a best practice.
By default, the data recovery service is located in the [***CDP_INSTALLATION_NAMESPACE***]-drs namespace. For example, if the CDP Private Cloud Data Services installation is located in the cdp namespace, the data recovery service namespace is automatically named cdp-drs. If you have multiple CDP Private Cloud Data Services installations (as in OCP), the data recovery service is named accordingly.
- Kubernetes resources associated with the cdp namespace and the embedded vault namespaces of the Control Plane in CDP Private Cloud Data Services. The resources include deployment-related information, stateful sets, secrets, and configmaps.
- Data used by the stateful pods, such as the data in the embedded database and Kubernetes persistent volume claim.
The Data Recovery Service requires CSI snapshots to back up and restore Kubernetes namespaces and resources. The CSI snapshots are enabled on ECS by default. You might require an additional license to enable CSI snapshots in Red Hat ODF storage on OCP.
Alternatively, you can use the CDP CLI options in CDP CLI drscp.
