Configure settings for NetBackup snapshot operation
You need to configure storage classes and volume snapshot class in order to protect the Persistent Volume Claims. After Netbackup Kubernetes Operator is installed, the following configuration needs to be done.
Identify the storage classes pointing to CSI plugin or if there is no storage class present then define a new storage class pointing to the CSI plugin.
Identify the Volume Snapshot Class pointing to CSI Plugin or If there is no volume snapshot class present then define a new volume snapshot class pointing to CSI plugin.
Define a VolumeSnapshotClass class consisting of CSI driver details.
Label the CSI Storage classes on the kubernetes cluster.
The storage class labels netbackup.veritas.com/default-csi-storage-class=true is used to label where storage class provisions volumes based on raw block (volumeMode=Block).
The storage class label netbackup.veritas.com/default-csi-filesystem-storage-class=true is used to label where storage class provisions volumes based on file system (volumeMode=FileSystem).
Note:
You can add both labels on a single storage class. If the storage class supports Block volume backed by raw block and the Filesystem volume.
Label the CSI Volume Snapshot Class for Netbackup usage
The label netbackup.veritas.com/default-csi-volume-snapshot-class=true must be applied to all CSI VolumeSnapshotClasses intended for snapshot operations with NetBackup.
Note:
Snapshot of a namespace consisting of persistent volume fails with an error message : Failed to create snapshot of the Kubernetes namespace. The snapshot operation may fail due to multiple reasons, for example a valid volumesnapshot class for the driver with valid label volumesnapshotclass is not found.
