What's New in Portworx Backup

What's new in 2.10.0?​

Version 2.10.0 – Released on Nov 24, 2025​

Features​

Integration with SUSE Rancher project based access control

Portworx Backup now provides seamless integration with SUSE Rancher's project based access control. Portworx Backup users now can view & access Kubernetes namespaces mapped to their Rancher project(s) based on their LDAP/SAML group membership obtained via popular providers like OpenLDAP or Ping Identity. This feature extends your access-control from SUSE Rancher into Portworx Backup, preventing unauthorized or unintended data exposure by enforcing namespace-level filtering based on Rancher's Projects configuration.

Flexible namespace management

Portworx Backup introduces flexible namespace management capabilities that allow scheduled backups to gracefully handle missing namespaces, alongside ability to edit backup schedules to remove or add namespaces. Now the system proceeds to perform backup with available namespaces and marks the backup as Partial Success, if it finds some of the specified namespaces missing. This feature improves backup resilience even when namespace availability changes and provides greater usability by allowing users to remove or append namespaces to schedule.

Password customization for internal databases

Portworx Backup now has easier mechanism based on Kubernetes secrets, to provide and rotate credentials for its internal databases. You can also enable optional encryption of the internal-database and specify encryption keys via Kubernetes secret. Now making Portworx Backup's security and protection capabilities more usable.

mTLS support for Portworx Backup

Portworx Backup can now run with mTLS when deployed into a customer‑managed service mesh, enabling encrypted, mutually authenticated traffic across Portworx Backup microservices. This adds Helm managed integration for Istio and Linkerd, allowing UI access with HTTPs protocal aligning with enterprise security policies thus preventing unauthorized access and man-in-the-middle attacks.

Batch alerting for Backup schedules

Portworx Backup adds batch alerting for schedule operations, aggregating failures from pause, resume, and delete actions across multiple schedules into a single consolidated alert. Each alert lists the affected schedule objects with per‑object error reasons captured during each update cycle, so you can quickly pinpoint what failed and why. Alerts are grouped and continuously updated to reflect the current state - new failures are added and resolved items are removed - reducing email noise while preserving real‑time visibility.

Capture notes for backup schedule changes

Portworx Backup now lets you add a note when suspending, resuming, or editing schedules, including during bulk actions where a single note applies to all selected schedules. The latest note is shown when viewing schedule details, so that one can understand why backup schedule status was altered.

Granular backup sharing

Portworx Backup now extends its existing functionality for sharing backup, by allowing the sharer to specify with backup can be used for restore only (or) with full access rights by user or group with access to Backup Location and its Cloud Credential.

Backup and Restore FADA Volumes

The FADA volumes backup and restore feature has graduated from early access to general availability. It allows Portworx Backup to support FADA volume types effectively by using native Portworx snapshots (PXD-based) for both block and file system PersistentVolumeClaim (PVC) modes.

Enhancements​

Enhanced SSL/TLS Certificate Management for Ansible Module

The Portworx Backup Ansible collection now provides comprehensive SSL/TLS certificate management with support for custom CA certificates, mutual TLS authentication, and flexible certificate validation options. This enterprise-ready feature enables unified SSL configuration through inventory variables that automatically get applied across all modules, eliminating the need for per-module certificate setup while supporting self-signed certificates, private certificate authorities, and corporate PKI deployments for enhanced security in production environments.

Optional UUID for backup resources

Portworx Backup now supports optional UUID parameters across all interfaces (REST API, gRPC API, Ansible collection, and CLI), allowing users to reference backup resources using either human-readable names or UUIDs. This enhancement simplifies resource management by enabling users to work with user-defined names instead of complex UUID strings, while still maintaining UUID support for programmatic integrations that require guaranteed unique identifiers. The flexible approach improves user experience and scriptability while preserving backward compatibility with existing UUID-based workflows.

Generic backup repositories now leaner

Scheduled backup now uses split backup repositories for generic (KDMP) backups, creating smaller schedule‑bound repositories per PVC. Only when the incremental threshold is reached, a new full backup is started in the new repo. Thus keeping repositories small and stable, reducing maintenance time on large datasets. Portworx Backup also has improved cleanup mechanisms employed, ensuring zero size snapshots are removed and stale folders are periodically pruned. Thereby preserving active data and improving space reclamation in your backup locations. This enhancement is compatible when using Portworx Backup 2.9.x+ alongwith Stork 25.2.x+. In such environments, on Portworx Backup upgrade - schedules are migrated to allow new capabilities, while existing backups continue to work in their current layout.

In addtion, a few issues are also resolved. For more information, see Release Notes.

Version 2.9.1 – Released on August 26, 2025​

A few issues are resolved. For more information, see Release Notes.

Version 2.9.0 – Released on July 08, 2025​

Features​

  • Retry backups at VM level: you can now retry only failed VMs in VM backups without reprocessing successful ones, reducing load on backup server. This feature helps maintain efficient backup operations, provides granular control on VM backups and ensures better adherence to RPO targets.

  • PXB deployment on proxy-enabled clusters: you can deploy PXB in proxy-enabled Kubernetes cluster environments across all supported platforms, except IKS. It supports proxy configuration with Helm values or Kubernetes secrets passed as Helm parameters during PXB installation or upgrade.

  • Bulk schedule operations: you can now suspend, resume, or delete multiple backup schedules in bulk, simplifying backup management across large environments. In addition, you can filter schedules by their names, schedule policies, or a combination of both to precisely target the desired schedules.

  • Back up volume resources: you can now back up only the Kubernetes PersistentVolume (PV) and PersistentVolumeClaim (PVC) specifications without including the actual volume data. This helps to optimize backup jobs by reducing data footprint, improving performance, and avoiding redundancy when the volume data is protected through other mechanisms like external snapshots or NFS backups.

Enhancements​

  • Enhanced web console:
    • The PXB web console is enhanced with detailed insights, offering clearer status indicators and granular VM backup information for effective monitoring and management.
    • Web console features a new, intuitive left navigation pane designed for easier access to key functions and a smoother user experience.
    • You can sort few columns in Backup, Restore, and All Backups page either in ascending or descending order by clicking on the arrows at the end or beginning of the column name. When the data is not sorted, page always displays the latest record first.

Fixes​

Version 2.8.4 – Released on April 14, 2025​

Features​

  • Advanced filtering: Portworx Backup allows you to filter VMs and namespaces based on the labels assigned to them and their associated resources. This helps you narrow down the list of virtual machines (VMs) and namespaces for backup operations. You can enter specific namespace or VM labels to view only the resources that match those criteria. This is especially useful in large environments where you need to focus on a subset of resources. By filtering based on labels, you can streamline management, improve performance, and reduce the risk of backing up unnecessary data. The feature enhances precision and efficiency in your backup workflows.

  • Partial success of VM backups: The Partial Success for VM Backup feature improves backup reliability by executing PreExec and PostExec rules on a per-VM basis, instead of applying them to all VMs at once. This granular handling ensures that if one VM fails during execution rule processing, only that VM is marked as failed, and the backup continues with the remaining VMs. Volume failures are now tracked and reported per VM, enabling accurate success/failure status and reducing unnecessary backup failures.

Enhancements​

  • Backup Retry: you can now re-initiate a backup job if some volumes have failed in your multi-VM or multi-namespace backups. In other words if your VM or namespace backup has partially succeeded or completely failed, you can re-initiate the backup job with Retry option.

  • VMs with static IPs: PXB has introduced two new annotations to provide enhanced control over static IPs and MAC addresses of VMs:

    • px-backup/skip-vm-start: stops the VM until users start the VM manually after restore with this annotation, giving them the opportunity to configure a new static IP and avoid conflicts.
    • px-backup/skip-mac-masking: this annotation allows users to retain the original MAC address, which is beneficial for preserving network identity.

Fixes​

Version 2.8.3 – Released on Feb 12, 2025​

Features​

  • Health Check: the health check feature enhances pre-installation and upgrade validations, including Kubernetes version checks, storage class validation, and blocking unsupported upgrade paths. It simplifies debugging with detailed reports, user-friendly error messages, and helm enhancements, to ensure smoother deployments. Besides, health check enhances user experience in install and upgrade scenarios.

  • Parallel Backup Schedule: this feature ensures that scheduled backups occur at every scheduled interval, even if the previous backup is still in progress. It allows subsequent backups to start as long as all Portworx volume snapshots are complete and the user has opted for parallel backup schedules.

Enhancements​

  • Email Alerts with SMTP TLS: this enhancement improves email security by enabling encrypted connections using STARTTLS and custom certificates. With this improvement, users can ensure compliance with organizational security standards by uploading their own certificates, including CA certificates. It supports secure communication over commonly used SMTP ports (25, 465, and 587) and ensures robust encryption for email validation and transmission.

  • KubeVirt enhancements: Portworx Backup now enables you to back up and restore VirtualMachineInstancetype, VirtualMachinePreference and NetworkAttachmentDefinition KubeVirt VM resources in your VM backup environment.

  • Argo CD Mode of Deployment: you can now install Portworx Backup with Argo CD in simple steps by setting few parameters during deployment. This enhancement brings a GitOps-driven approach to manage data protection and ensures that backup policies, schedules, and configurations are applied consistently across environments.
