The short version

  • Only Portworx Backup has a free tier, so it costs nothing to try first.
  • Each has a real cost: Comet Backup per-endpoint costs ($2/month per endpoint) can add up for large deployments with many protected machines; 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: Comet Backup covers White-label branding, 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.

Comet Backup

  • Per-endpoint costs ($2/month per endpoint) can add up for large deployments with many protected machines
  • Advanced and Enterprise tiers with additional management capabilities are significantly more expensive than base tiers
  • Platform-specific features (SQL, MySQL, MongoDB, Microsoft 365) have separate per-unit pricing

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.

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.

Comet Backup: What is the price difference between self-hosted and cloud-hosted deployments?

Cloud-hosted plans start at $49/month (Professional) versus self-hosted which starts at $19/month (Starter). The main advantage of cloud-hosted is Comet manages the console infrastructure, though both models charge the same per-endpoint fees.

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

Comet Backup: Does Comet Backup charge for additional protected machines?
