The short version

  • Each has a real cost: Buildah linux only, with no native macOS or Windows support; 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.
  • They diverge on capability: Buildah covers Daemonless builds, Portworx Backup covers Application-level backup.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Buildah

  • Linux only, with no native macOS or Windows support
  • Scriptable builds are powerful but less portable and less familiar than a Dockerfile
  • Narrow by design: it builds images and does not run them, so it needs Podman or another runtime alongside

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 from the vendors’ own pages

Buildah: Is Buildah free?

Yes, open source with no licence fee.

Portworx Backup: 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.

Buildah: Do I still need a Dockerfile?

No. Buildah reads Dockerfiles if you have them, but images can be built entirely from shell commands instead.

Portworx Backup: Does it only protect Portworx volumes?

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

Buildah: How is Buildah different from Podman?

Buildah builds images; Podman runs them. Podman actually embeds Buildah for its build command, and the two are designed to be used together.

Portworx Backup: Is it included with Portworx Enterprise?

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