Where each one falls short

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

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

Packer

  • Packer 1.10.0 and later is licensed under the Business Source License 1.1 with IBM Corporation as licensor, not an OSI open source licence
  • The Additional Use Grant forbids offering Packer to third parties on a hosted or embedded basis in a paid product that competes with IBM's paid versions of Packer
  • Each version converts to the MPL 2.0 Change License only four years after that version is first published, and the Change Date is set separately per version
  • Alternative licensing for uses outside the grant must be arranged with the licensor rather than taken under the public licence
