The short version

  • Only Kopia has a free tier, so it costs nothing to try first.
  • Each has a real cost: Datto Backup no pricing information published on product page or dedicated pricing page; Kopia space is only reclaimed when maintenance runs, and in a shared repository full maintenance is owned by one client, so if that machine goes away the repository grows for ever while every backup still reports success.
  • 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.

Datto Backup

  • No pricing information published on product page or dedicated pricing page
  • Vendor directs users to contact sales for pricing information
  • No published tiers or pricing models disclosed

Kopia

  • Space is only reclaimed when maintenance runs, and in a shared repository full maintenance is owned by one client, so if that machine goes away the repository grows for ever while every backup still reports success.
  • The repository format has changed across versions and mixing client versions against one repository is discouraged, so a fleet must be upgraded together rather than machine by machine.
  • There is no central orchestration or reporting for many machines, so monitoring a fleet means building your own alerting around exit codes.
  • Restoring many small files is slower than the backup was, because content must be reassembled from pack blobs, and this is rarely tested until the day it matters.
  • Encryption is client side with no escrow, so a lost repository password means the data is unrecoverable and there is no vendor to appeal to.

Answered from the vendors’ own pages

Datto Backup: How is Datto Backup priced?

Datto does not publish specific pricing for Backup on their website. Pricing details require contacting Datto's sales team directly through their website.

Source
Kopia: Is a partly corrupt repository still restorable?

Partly. Deduplication means one damaged pack blob affects every snapshot referencing its contents, but unaffected files still restore. Run verification regularly rather than assuming.

Datto Backup: Does Datto offer different backup pricing tiers or plans?

The public product pages do not detail pricing tiers or plan structures. Organizations must request quotes from Datto to learn about available options and tier pricing.

Source
Kopia: How does it compare with restic?

Similar guarantees, with packing that behaves better on per operation billing, a desktop interface, and compression enabled by default.

Datto Backup: What backup and business continuity features does Datto provide?

Datto Backup provides comprehensive business continuity frameworks, threat monitoring, malware insights, and disaster recovery capabilities, but specific features by pricing tier are not publicly disclosed.

Source
Kopia: Do I need to run maintenance manually?

It is scheduled automatically by default, but you must ensure the client that owns full maintenance keeps running, otherwise deleted snapshots never free space.

Datto Backup: How would I request Datto Backup pricing information?

Datto customers can request pricing through the website's pricing links in footer navigation or by contacting their sales team. Partners may access customized pricing through Datto's partner portal.

Source
Kopia: Can several machines share one repository?

Yes, and that is where deduplication pays off, but they should run compatible versions and only one owns full maintenance.
