The short version

  • Only Kopia has a free tier, so it costs nothing to try first.
  • Each has a real cost: Cohesity DataProtect primarily focused on enterprise customers; less suitable for small businesses; 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.
  • They diverge on capability: Cohesity DataProtect covers Hyperconverged architecture, Kopia covers Content defined chunking.
  • 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.

Cohesity DataProtect

  • Primarily focused on enterprise customers; less suitable for small businesses
  • Requires significant IT expertise to optimize deduplication and retention policies
  • High upfront infrastructure costs for on-premises deployment

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

Cohesity DataProtect: What is the main benefit of Cohesity DataProtect's instant recovery?

Cohesity uniquely reduces downtime by enabling instant mass restoration of any number of VMs, large volumes of unstructured data, and Oracle databases to any point in time.

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.

Cohesity DataProtect: How much can Cohesity reduce data protection costs?

Cohesity DataProtect reduces data protection costs by 70% or more through unified management and deduplication.

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.

Cohesity DataProtect: What platforms and workloads does Cohesity DataProtect support?

Cohesity DataProtect protects on-premises systems, multiple cloud environments, and SaaS applications through a single unified platform.

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.

Cohesity DataProtect: Does Cohesity use security best practices for backup protection?

Yes. Cohesity DataProtect uses multilayered security architecture designed to minimize the risk of backups becoming a ransomware target.

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.
