The short version

  • Only Kopia has a free tier, so it costs nothing to try first.
  • Each has a real cost: Bacula Enterprise pricing is not published; the vendor asks for a request rather than listing rates; 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: Bacula Enterprise covers Modular architecture, Kopia covers Content defined chunking.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

  • Keeping an encrypted offsite copy where the storage provider must never be able to read the contentsnot Bacula Enterprise

Where each one falls short

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

Bacula Enterprise

  • Pricing is not published; the vendor asks for a request rather than listing rates
  • The differences between Enterprise and the open source Community edition are not set out on the product pages, so what the licence buys is unclear until you talk to sales
  • Aimed at data centre and enterprise environments rather than small deployments

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

Bacula Enterprise: Does Bacula Enterprise offer a trial?

Yes. Bacula offers a trial that provides 'a streamlined version of Bacula Enterprise' with 'rapid access to an online, hosted environment'. However, no specific trial period duration is stated on the page.

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.

Bacula Enterprise: Is there a free trial available, or does it require contacting sales?

The trial is available directly online without needing to contact sales first. The page provides streamlined access to test the service with Global Endpoint Deduplication and cloud storage capabilities.

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.

Bacula Enterprise: Does Bacula charge by data volume?

No. One customer testimonial states 'we are not charged by data volume or hardware', indicating that Bacula does not use capacity-based pricing like some competitors.

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.

Bacula Enterprise: How can I get Bacula pricing information?

Bacula directs interested parties to Request Pricing through their contact page rather than displaying rates publicly.

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.
