  • They diverge on capability: Packer covers Image building, Restic covers Content-defined chunking.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

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

Restic

  • Cold storage is not natively supported; restoring from S3 Glacier and S3 Glacier Deep Archive is only available as an experimental feature behind a feature flag
  • A Windows file whose name contains a character Windows treats as invalid cannot be read by restic and has to be renamed
  • Antivirus real-time protection degrades performance on Windows unless the restic binary is added to an exclusions list
  • On large repositories the built-in five minute stuck-request timeout fires during file listing and has to be raised manually with --stuck-request-timeout
