Back up FADA volumes
You can now backup Kubernetes applications that mount PersistentVolumeClaims (PVCs) provisioned with FADA (pure_block) volumes. This topic outlines the prerequisites and supported backup locations such as NFS, Amazon S3, and Azure Blob for backing up these workloads. This Early Access feature supports compatibility with multiple Kubernetes platforms, both manual and scheduled backup workflows, and cross-cluster restore capabilities with appropriate Portworx configuration. This functionality is intended for non-production use only and should be evaluated in testing environments.
This section guides you through backing up applications that mount PersistentVolumeClaims (PVCs) provisioned with FADA (pure_block) storage using Portworx Backup.
PXB can now handle these FADA volume types effectively, using native Portworx snapshots (PXD-based) for both block and file system PVC modes. KDMP-based backups are only supported for PVCs in file system mode.
Prerequisites
-
An application up and running with FADA volume mounted to it
-
Add the following parameter in
kdmp-configConfigMap (inkube-systemnamespace) on all the application clusters:ENABLE_PX_FADA_BACKUP: true
This flag enables Portworx Backup to back up FADA-backed PVCs (volumes provisioned using
pure_block). -
Portworx Enterprise 3.4.0 and above
-
Stork version 25.3.0 and above
