As organizations modernize their infrastructure, Kubernetes is increasingly becoming a platform for both containers and virtual machines.
Running workloads on Kubernetes is only part of the challenge. Protecting the data behind those workloads is just as critical.
Traditional virtualization platforms provide mature backup and recovery capabilities. As organizations move virtual machines and stateful applications onto Kubernetes, they expect the same reliability and operational flexibility from their data protection tools.
Platform engineers and infrastructure architects must answer practical questions such as:
- How do we recover individual files from VM backups without restoring an entire virtual machine?
- How do we protect large Kubernetes environments without impacting cluster performance?
- How do backup policies adapt as new applications and namespaces are deployed?
- How do we restore specific resources without disrupting running workloads?
At KubeCon this year, we are sharing how Portworx Backup is helping redefine modern virtualization by delivering enterprise-grade data protection for Kubernetes environments.
The latest release of PX-Backup 2.11.0 introduces new capabilities designed to improve recovery precision, backup efficiency, and operational flexibility for modern Kubernetes infrastructure.
Protecting Modern Kubernetes Environments
Kubernetes environments are dynamic by design. Applications scale rapidly, clusters evolve frequently, and infrastructure changes are common.
Protecting data in this environment requires more than traditional backup workflows. Platform teams need tools that understand Kubernetes resources, application relationships, and the scale of modern cloud-native environments.
PX-Backup provides Kubernetes-native data protection that integrates directly with the cluster. It enables administrators to protect applications, virtual machines, and infrastructure resources across Kubernetes environments.
PX-Backup 2.11.0 builds on this foundation with several enhancements designed to improve recovery workflows and scalability.
Granular Recovery with VM File Level Backup & Restore
One of the most common recovery scenarios in virtualization environments is restoring a single file from a virtual machine.
PX-Backup 2.11.0 introduces VM File Level Backup & Restore, enabling administrators to recover individual files or directories from VM backups without restoring the entire virtual machine or volume.
This capability allows operators to quickly recover:
- Accidentally deleted files
- Corrupted configuration files
- Logs required for troubleshooting or auditing
- Individual application data within large VM volumes
Why this matters
Traditional VM recovery workflows often require restoring an entire virtual machine or disk just to retrieve a single file.
VM File Level Backup & Restore enables targeted recovery operations. Teams can restore only the required data while leaving the rest of the workload untouched. This reduces recovery time and simplifies incident response.
Granular Restore for Kubernetes Resources
PX-Backup 2.11.0 also introduces granular restore capabilities for large Kubernetes resource backups.
Administrators can selectively restore individual Kubernetes resources such as:
- Deployments
- ConfigMaps
- Secrets
- Specific namespaces
Why this matters
Restoring entire backups can disrupt workloads that are still functioning correctly.
Granular restore allows operators to recover only the affected resources, reducing downtime and minimizing the operational impact of recovery operations.
Volume Resource-Only Backup
PX-Backup 2.11.0 expands on the Volume Resource-Only Backup introduced in PX Backup 2.9 with full UI integration. This allows administrators to back up Kubernetes volume definitions such as PersistentVolumeClaims (PVCs) and PersistentVolumes (PVs) without copying the underlying storage data all from the PX-Backup UI, increasing usability for backup admins.
Why this matters
In many environments, the underlying storage platform already provides its own data protection.
Backing up only Kubernetes resource definitions allows administrators to restore volume metadata quickly and rebind existing storage volumes during cluster upgrades, migrations, or redeployments.
By integrating this into the PX-Backup UI, backup admins can now easily reduce backup time and avoid unnecessary data transfers.
Dynamic Backup Scheduling
Kubernetes environments evolve continuously as new applications, namespaces, and services are deployed.
PX-Backup 2.11.0 introduces the ability to modify label selectors for existing backup schedules, allowing administrators to adjust backup coverage without recreating schedules.
Platform teams can:
- Add new applications to existing backup policies
- Remove workloads temporarily during maintenance
- Expand backup coverage as environments grow
Why this matters
Static backup policies are difficult to maintain in rapidly changing Kubernetes environments.
Dynamic scheduling allows backup policies to evolve alongside the environment they protect while maintaining consistent protection across workloads.
Scalable Backup Metadata Architecture
Large Kubernetes environments can generate significant metadata during backup operations.
PX-Backup 2.11.0 introduces a Resource Split architecture, replacing a single monolithic metadata file with a structured layout organized by namespaces and virtual machines.
Why this matters
As clusters scale, large metadata files can consume significant memory during backup and restore operations.
The new architecture improves scalability by reducing memory usage, improving resiliency during uploads, and enabling faster partial restores.
This allows PX-Backup to operate efficiently in large enterprise environments.
Granular Restore for Kubernetes Resources
PX-Backup 2.11.0 also introduces granular restore capabilities for large Kubernetes resource backups.
Administrators can selectively restore individual Kubernetes resources such as:
- Deployments
- ConfigMaps
- Secrets
- Specific namespaces
Why this matters
Restoring entire backups can disrupt workloads that are still functioning correctly.
Granular restore allows operators to recover only the affected resources, reducing downtime and minimizing the operational impact of recovery operations.
Redefining Backup for Modern Virtualization
As organizations consolidate infrastructure onto Kubernetes, data protection must evolve alongside the platform.
Modern environments run a mix of containers, stateful services, and virtual machines. Protecting these workloads requires backup solutions that understand Kubernetes resources, application relationships, and the scale of modern cloud-native infrastructure.
PX-Backup 2.11.0 introduces capabilities that help platform teams protect Kubernetes workloads with greater precision and efficiency. These enhancements improve recovery workflows, increase scalability, and simplify backup operations.
Together with Portworx Enterprise, PX-Backup enables organizations to redefine backup for modern virtualization by delivering enterprise-grade data protection for containerized applications, AI/ML workloads and virtual machines running on Kubernetes.
