Borg Backup

  • Linux, macOS and BSD only; Windows is not a supported platform
  • Command-line only, with no graphical interface in the project itself
  • Version 2.0 is still in beta, so production use means staying on the 1.4 line
  • Restoring requires the Borg tooling, since archives are a deduplicated chunk store rather than plain files

Duplicati

  • No managed service or commercial support
  • Relies on community support
  • No enterprise features
