  • Only rustic has a free tier, so it costs nothing to try first.
  • Each has a real cost: Altaro VM Backup limited to small and medium-market businesses with up to 50 host servers; 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: Altaro VM Backup covers Augmented inline dedup, rustic covers restic format compatibility.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Altaro VM Backup

  • Limited to small and medium-market businesses with up to 50 host servers
  • Perpetual license model outdated compared to modern cloud-based backup solutions
  • Lacks enterprise-grade features for large-scale deployments
  • Offsite backup to cloud requires additional setup and configuration

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.
