Where each one falls short

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

Buildah

  • Linux only, with no native macOS or Windows support
  • Scriptable builds are powerful but less portable and less familiar than a Dockerfile
  • Narrow by design: it builds images and does not run them, so it needs Podman or another runtime alongside

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

No. Buildah reads Dockerfiles if you have them, but images can be built entirely from shell commands instead.
