The short version

  • Each has a real cost: containerd not a developer-facing tool: there is no build command and the CLI is deliberately minimal, so it needs companions like nerdctl or Buildah; 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
  • They diverge on capability: containerd covers Full container lifecycle, 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.

containerd

  • Not a developer-facing tool: there is no build command and the CLI is deliberately minimal, so it needs companions like nerdctl or Buildah
  • Debugging is lower-level than Docker, and error messages assume knowledge of the runtime internals
  • Documentation is aimed at platform engineers, so newcomers usually find Docker or Podman material more useful
  • No image building at all — that is out of scope by design

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

Answered from the vendors’ own pages

containerd: Is containerd free?

Yes. It is an open-source CNCF graduated project with no licence fee.

Restic: How much does restic cost?

Restic is entirely free to use and completely open source. There are no subscription tiers, paid plans, or licensing costs.

containerd: Do I need containerd if I use Docker?

You already have it. Docker uses containerd underneath to run containers; it is not an alternative you install separately.

containerd: Why did Kubernetes drop Docker for containerd?

Kubernetes talks to runtimes through the Container Runtime Interface. Docker did not speak CRI natively and needed a shim, so Kubernetes removed the shim and talks to containerd directly, which Docker was already using anyway.

containerd: Can containerd build images?

No. Image building is deliberately out of scope. Tools such as Buildah, BuildKit or Docker handle that.
