The short version

  • Each has a real cost: Duplicacy web GUI pricing tier not specified on product page; 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: Duplicacy covers Lock-free deduplication, 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.

Duplicacy

  • Web GUI pricing tier not specified on product page

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.
