The short version

  • Each has a real cost: Duplicati no managed service or commercial support; MinIO the AGPL v3 licence applies copyleft over network use, so embedding MinIO in a product or hosted service obliges you to release your own source or buy a commercial licence, and legal review has removed it from several vendor stacks for this reason alone.
  • They diverge on capability: Duplicati covers AES-256 encryption, MinIO covers S3 API implementation.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Duplicati

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

MinIO

  • The AGPL v3 licence applies copyleft over network use, so embedding MinIO in a product or hosted service obliges you to release your own source or buy a commercial licence, and legal review has removed it from several vendor stacks for this reason alone.
  • The community edition console was reduced in 2025 to an object browser, so user, policy, bucket and configuration management now happen through the mc command line client or through the paid product, which is a real operational regression for teams that trained staff on the UI.
  • The vendor has changed the terms of the free edition twice, so planning long lived infrastructure around the community build carries the risk that the next change removes something you depend on.
  • Erasure coded deployments cannot be grown by adding single drives; capacity is added in server pools, so expansion is a hardware purchase in units rather than an incremental one.
  • Commercial pricing is capacity based and aimed at large deployments, so a team that outgrows the community edition faces an enterprise sized quote rather than a graduated upgrade path.

Answered from the vendors’ own pages

Duplicati: Is Duplicati free?

Yes. Duplicati is completely free and open-source under the LGPL license. There are no premium tiers, trials, or limitations.

Source
MinIO: Can I still use MinIO for free?

Yes, the AGPL v3 server remains available and functional. What changed is the console, which no longer manages users, policies or configuration in the community build.

Duplicati: What does Duplicati support?

Duplicati supports zero-trust, fully encrypted backups to local storage, network drives, and cloud services. It includes deduplication and incremental backups.

Source
MinIO: Does AGPL affect me if I only use it internally?

Internal use without offering the software over a network to third parties generally does not trigger the source obligation, but if MinIO forms part of a service you offer to others, it does. Take advice rather than a forum answer.

Duplicati: What are the platforms?

Duplicati runs on Windows, macOS, and Linux. It can back up data to local storage, network drives, or cloud providers.

Source
MinIO: What replaced the community console features?

The mc client and the server admin API. Third party UIs exist but they are not maintained by MinIO.

MinIO: Is it suitable as a Veeam or restic backup target?

Yes, object locking and versioning work and both tools treat it as standard S3. Immutability depends on configuring the lock policy at bucket creation.
