Portworx Backup

Kubernetes application backup with a free tier up to one terabyte

As of 1 September 2026, Portworx Backup has a free plan and paid plans start at $0.2/node hour. A Kubernetes-aware backup service from Pure Storage that protects applications rather than volumes, with a genuinely free tier protecting up to one terabyte and paid usage at 0. Softwr lists it under Backup. Portworx Backup is made by Portworx by Pure Storage, available on Web, Linux.

Overview

What Portworx Backup does

Portworx Backup, previously PX-Backup, backs up Kubernetes applications as units: the resource definitions, the persistent volume data and the configuration that ties them together. It works across Container Storage Interface providers rather than only against Portworx volumes, so it protects clusters using cloud provider storage or another vendor's driver, and it restores into a different cluster or a different cloud. The distinguishing commercial fact is the free tier. Pure offers a fully managed free tier with no feature restrictions protecting up to one terabyte, which is enough to run real production backups for a small platform team and enough to evaluate the product properly without a sales process. Paid consumption is 0.20 US dollars per node hour with a 1,000 node hour monthly minimum, and it is licensed separately from Portworx Enterprise; buying storage does not give you backup. Buyers are platform teams already running Kubernetes in production, particularly those who started with Velero and hit the support question. The trade-off is that it is another Pure Storage subscription with its own minimum, and that backup is only as good as the restore rehearsal; Kubernetes application recovery still requires you to understand your own dependency ordering, whatever the product does automatically.

What people use it for

  • A platform team running Velero that needs an accountable vendor for restore failures
  • Protecting Kubernetes applications across EKS, GKE and on premises clusters under one policy set
  • Restoring a namespace into a different cloud provider as a disaster recovery test
  • A small team that wants real Kubernetes backup within the free one terabyte tier before committing budget

The honest half

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Portworx Backup.

  • The paid tier carries a 1,000 node hour monthly minimum, so a cluster that only needs occasional protection still pays a floor.
  • It is licensed separately from Portworx Enterprise, so organisations that assumed storage and backup came together find a second subscription in the quote.
  • The free tier caps at one terabyte of protected data, which is quickly exceeded by any database of consequence and forces a jump straight to the minimum commitment.
  • Backup targets are object stores you provide, so restore egress charges from your cloud provider are outside the vendor price and appear during a recovery rather than in procurement.
  • Application-consistent backup of databases still depends on correct pre and post hooks, so the product does not remove the requirement to understand and rehearse your own restore ordering.

Answered, with sources

Questions people ask

Each answer names the page it came from, so you can check it rather than take our word for it.

Is the free tier real?

Yes, up to one terabyte of protected data with no feature restrictions as a managed service. It is a usable production tier for small footprints, not a trial.

Does it only protect Portworx volumes?

No. It works across Container Storage Interface providers, including cloud provider storage and other vendors' drivers.

Is it included with Portworx Enterprise?

No. It is a separate licence at 0.20 USD per node hour with its own minimum.
