The short version

  • Only rustic has a free tier, so it costs nothing to try first.
  • Each has a real cost: Cohesity no pricing details published on website; rustic the project is small with a short list of active maintainers, so bus factor is a genuine consideration for software whose job is to still work in five years.
  • Prices and features above were last checked on 31 August 2026.

Cohesity

  • No pricing details published on website
  • Advanced edition status listed as coming soon
  • Requires contacting sales team for quotes
  • No self-service pricing tiers or calculator available

rustic

  • The project is small with a short list of active maintainers, so bus factor is a genuine consideration for software whose job is to still work in five years.
  • It inherits the restic repository format, so design limits in that format, including the cost of pruning large repositories, are inherited rather than fixed.
  • Command names, flags and behaviour do not map one to one onto restic, so scripts and runbooks need rewriting rather than a binary swap.
  • Far fewer people have performed a real restore from it under pressure, and backup software is one of the few categories where being second most used is itself a risk.
  • Alternating between rustic and restic against one repository works but doubles the surface for a version incompatibility to corrupt state, so most operators should pick one and stay with it.
