The short version

  • Each has a real cost: Cilium requires a recent Linux kernel, which rules out older distributions and some managed environments; Clonezilla the destination partition must be equal to or larger than the source partition
  • They diverge on capability: Cilium covers eBPF datapath, Clonezilla covers Disk/partition imaging.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

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

Clonezilla

  • The destination partition must be equal to or larger than the source partition
  • Differential and incremental backup is not implemented
  • Online imaging and cloning is not implemented; the partition being imaged or cloned has to be unmounted first
  • The image format cannot be explored or mounted, so a single file cannot be recovered from an image
  • Recovery media spanning multiple CDs or DVDs is not implemented; the recovery ISO must fit on one disc
  • Clonezilla SE requires a DRBL server to be prepared in advance and the target machine to boot from the network
  • Runs only on x86 or x86-64 processors and needs at least 196 MB of RAM

Questions people ask

Is Cilium or Clonezilla better?
Neither clearly leads. Cilium starts at Free and Clonezilla at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Cilium or Clonezilla?
Cilium starts at Free and Clonezilla at Free.
Does Cilium or Clonezilla run on more platforms?
Cilium runs on Kubernetes, Linux. Clonezilla runs on Linux, Windows.
Can I use Cilium for free?
Both have a free tier, so you can try either at no cost before committing.
What is Cilium best used for?
Cilium is most often used for kubernetes networking at a scale where iptables-based cni performance degrades, network policy expressed on workload identity rather than fragile ip rules, seeing which services actually talk to each other, and what policy is dropping. Of those, kubernetes networking at a scale where iptables-based cni performance degrades and network policy expressed on workload identity rather than fragile ip rules are not what Clonezilla is typically brought in for.
What can Cilium do that Clonezilla cannot?
Cilium covers eBPF datapath, Identity-based policy, Hubble observability, Sidecar-free mesh. Clonezilla covers Disk/partition imaging, Disk cloning, Multicast deployment, Multiple file systems.

Answered from the vendors’ own pages

Cilium: Is Cilium free?

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

Clonezilla: Is Clonezilla free?

Yes, Clonezilla is completely free and open-source software licensed under GNU General Public License version 2. There are no paid versions, premium features, or subscription costs.

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.

Clonezilla: What Clonezilla editions are available at no cost?

All three editions are free: Clonezilla Live for individual machine backups, Clonezilla Lite Server for mass deployment, and Clonezilla SE for large-scale enterprise cloning operations.

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.

Clonezilla: Can I use Clonezilla commercially?

Yes, Clonezilla's GPL v2 license allows free commercial use. The software is open-source and requires no licensing fees for any deployment scenario.
