The short version

  • Each has a real cost: IBM Storage Protect iBM United Kingdom Limited lists IBM Storage Protect for Cloud (Microsoft 365 edition) on G-Cloud 14 at £50.64 per user per year; 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.
  • They diverge on capability: IBM Storage Protect covers Progressive incremental backup, rustic covers restic format compatibility.
  • Prices and features above were last checked on 31 August 2026.

IBM Storage Protect

  • IBM United Kingdom Limited lists IBM Storage Protect for Cloud (Microsoft 365 edition) on G-Cloud 14 at £50.64 per user per year

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.

Answered from the vendors’ own pages

rustic: Can it read my existing restic repository?

Yes, that is the point of the project. Take a copy and verify before you rely on it, as with any change to backup tooling.

rustic: Should I switch from restic?

Only for a specific reason such as configuration profiles, memory use or cold storage handling. Compatibility means there is no cost to trying and no cost to going back.

rustic: Is it production ready?

It is used in production by a small community, but it is younger and less exercised than the implementation it is compatible with. Test restores accordingly.

rustic: Does it support the same back ends?

The common ones, including local, SFTP, S3 compatible storage and rclone. Check the current list before committing to an unusual target.
