Backup

The following topics explain different backup types that you can perform using Portworx Backup.

Once you have defined the necessary backup rules and schedule policies, you can create manual or scheduled backups for namespaces or virtual machines (VMs) using Kubernetes Data Management Platform (KDMP) or CSI (Container Storage Interface) drivers. These backups can be stored on any object store (S3 and others) or NFS share backup locations.

note

1. NFS-based backup location supports generic, manual, and scheduled backups.

2. Starting from Portworx Backup version 2.6.0, users cannot take a backup of kube-system, kube-node-lease, kube-public namespace and the namespace where Portworx is installed for any of the cluster environments that Portworx Backup currently supports.

3. Ensure that the cluster is in active and not in disconnected status before creating a backup of your application data.

4. To restore local snapshots backed up by parallel schedules, please contact Pure Storage support.

Following topics take you through the steps for creating various types backups supported by Portworx Backup:

🗃Manual Backups

Learn how to create and manage manual backups in Portworx Backup. Manual backups are one-time backup operations that you create on-demand without a schedule policy, providing flexibility for immediate data protection needs.

🗃Scheduled Backups

Learn how to create and manage scheduled backups in Portworx Backup. Scheduled backups automate your backup operations at specified intervals, ensuring consistent data protection without manual intervention.

📄️Create a Cross Cloud Backup

This topic provides instructions for creating a cross cloud backup using Portworx Backup and the KDMP driver. It explains how to back up namespaces or VMs across different cloud environments and restore them in another cloud. The guide covers manual and scheduled backups, including how to map storage provisioners to volume snapshot classes, apply pre-exec and post-exec rules, and add labels for easier management. It also provides details on selecting backup locations and associating schedule policies to automate backups.

📄️Back up Volume Resources

Learn how to configure Volume Resource-Only Policy (VROP) in Portworx Backup to back up only PVC/PV specifications without including volume data.

📄️Back up Portworx Volumes

📄️Create a CSI Backup

This topic provides instructions for creating a CSI backup using Portworx Backup, which allows users to create application-aware CSI snapshots and offload them to object store or NFS-based backup locations. The guide explains how to configure backup locations, map volume snapshot classes (VSC) to storage provisioners, and use pre-exec and post-exec rules for backup automation. It also covers manual and scheduled backups, and addresses handling CSI snapshots with Portworx and non-Portworx provisioners to ensure secure, compliant, and reliable data protection for Kubernetes applications.

📄️Create Object Lock Enabled Scheduled Backup

This topic provides instructions on how to create an object lock enabled scheduled backup in Portworx Backup for securing data in S3-compliant object stores. It explains how to configure a scheduled backup with retention settings, mapping storage provisioners to volume snapshot classes, and applying pre-exec and post-exec rules. The topic also covers updating object lock enabled backups, including adding or deleting labels to filter backups for better management and protection from unauthorized changes during the retention period.

📄️Create Backups with Advanced Filters

Use label-based filters to include or exclude specific namespaces when creating manual or scheduled backups. This feature allows more precise control over what gets backed up, streamlining operations in large, dynamic, or multi-tenant Kubernetes environments.

🗃Virtual Machine backups

Learn how to back up and restore KubeVirt VMs using Portworx Backup. This guide provides detailed steps for creating VM backups, configuring backup locations, and using pre-exec and post-exec rules.

🗃Back up stateful applications

This topic provides guidance on using pre-exec and post-exec backup rules with Portworx Backup to achieve application-consistent backups for stateful applications. It explains how to leverage these rules to ensure data protection and consistency during the backup process for Kubernetes-based applications. The instructions cover best practices for managing and automating backups, disaster recovery, and implementing backup strategies with Portworx Backup.

📄️Back up on NFS Shares

This topic explains how to back up application data to Network File System (NFS) shares using Portworx Backup. It covers the prerequisites for configuring an NFS server, including enabling read and write permissions and ensuring communication through port 2049. The guide provides a sample NFS server configuration and details the steps for creating backups on NFS shares, which can be used for generic, manual, and scheduled backups. It also includes related information on restoring data from NFS backup locations.

📄️Back up with Large number of Resources

This topic explains how to back up namespaces containing a large number of resources using Portworx Backup. It provides detailed steps for performing backups efficiently and handling complex applications with numerous Kubernetes resources without interruption. The topic also covers how to manage resource selection, handle backups when resource counts exceed 1000, and customize settings through ConfigMap parameters in the `kube-system` namespace to optimize the backup process for large resource environments.

📄️Back up CRDs with Operator

This topic provides instructions for backing up Custom Resource Definitions (CRDs) across multiple groups using the `TRIM_CRD_GROUP_NAME` operator in the `kdmp-config` ConfigMap with Stork. It enables backing up CRDs that belong to the same operator but have different group names in Kubernetes. By configuring the `kdmp-config` map with the common group name, users can ensure that all relevant CRDs are included in the backup process for operator deployments.

📄️Back up NFS Shares

This topic explains how to back up NFS shares or NFS-based Persistent Volume Claims (PVCs) to any S3-compliant storage or public cloud using Portworx Backup. The Kubernetes Data Management Platform (KDMP) driver facilitates file system-based backups and restores of NFS-based PVCs. In cases where the storage provider does not support native snapshots, Portworx Backup accesses the volume directly from its mounted path on the host using a Kubernetes host path volume, running backups within a privileged container.
