The short version

  • Only Cilium 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; Cilium requires a recent Linux kernel, which rules out older distributions and some managed environments
  • They diverge on capability: Bacula Enterprise covers Modular architecture, Cilium covers eBPF datapath.
  • Prices and features above were last checked on 30 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Bacula Enterprise

  • Enterprise backup across virtual machines, databases and containersnot Cilium
  • Multi-cloud and hybrid backup from one systemnot Cilium
  • Backup where licensing by data volume would be prohibitive, since Bacula does not charge by capacitynot Cilium
  • Long-retention archival for regulated environmentsnot Cilium

Cilium

  • Kubernetes networking at a scale where iptables-based CNI performance degradesnot Bacula Enterprise
  • Network policy expressed on workload identity rather than fragile IP rulesnot Bacula Enterprise
  • Seeing which services actually talk to each other, and what policy is droppingnot 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

Cilium

  • Requires a recent Linux kernel, which rules out older distributions and some managed environments
  • eBPF is genuinely hard to debug when it misbehaves, and the skill is rare on most teams
  • Broad scope — CNI, policy, mesh, observability — means the learning curve covers several domains at once

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
Cilium: Is Cilium free?

Yes, open source and CNCF-graduated. Isovalent sells an enterprise distribution and support.

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
Cilium: What does eBPF change?

It lets Cilium run packet-processing programs inside the kernel instead of relying on iptables rule chains, which behave poorly as the number of services grows.

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
Cilium: Does Cilium replace a service mesh?

It can cover much of what a mesh does without sidecars, though full mesh feature sets still favour Istio or Linkerd.

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.
