Data Recovery Service overview
The Data Recovery Service (DRS) is a microservice in CDP Private Cloud that allows you to back up and restore Kubernetes namespaces and resources on both Embedded Container Service (ECS) and OpenShift Container Platform (OCP). Cloudera recommends that you create a backup of your Kubernetes namespace using DRS before a maintenance activity or in general, as a best practice.
- the Kubernetes resources associated with the cdp namespace and the embedded vault namespaces of the Control Plane. The resources include deployment-related information, stateful sets, secrets, and configmaps.
- the data used by the stateful pods, such as the data in the embedded database and Kubernetes persistent volume claim.
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
You must have the
PowerUser role to run the DRS commands using the CDP CLI.
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.
