This topic explains how you can back up NFS shares. To back up a namespace with a NFS-based PVC:
Follow the steps mentioned in the Create a backup topic to back up the external storage class with the NFS-based PVC.
The Kubernetes Data Management Platform (KDMP) is a driver in Portworx Backup that facilitates different data migration scenarios. It adds support for performing file system based backups and restore of PVCs. The KDMP driver in Portworx Backup can back up an NFS based PV, PVC from your local system. You can view the driver details by selecting the vertical menu icon on the backup -> View Json option:note
Consider a PVC backup that is actively in use by an application pod and the storage provider does not support native snapshot. If you request such a backup, then Portworx Backup accesses the volume directly from its mounted path on the host using the kubernetes hostpath volume. Such backups run within a privileged container in the kube-system namespace.
