The short version

  • Each has a real cost: Ceph ceph assumes an operator who understands placement groups, CRUSH rules and recovery tuning, so organisations without dedicated storage staff routinely end up with a cluster that works until the first failure and then does not.; Clonezilla the destination partition must be equal to or larger than the source partition
  • They diverge on capability: Ceph covers RADOS object store, Clonezilla covers Disk/partition imaging.
  • 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.

Ceph

  • Ceph assumes an operator who understands placement groups, CRUSH rules and recovery tuning, so organisations without dedicated storage staff routinely end up with a cluster that works until the first failure and then does not.
  • Small clusters are inefficient: three way replication means a third of raw capacity is usable, and erasure coding needs enough failure domains to be safe, so the economics only work above a certain size.
  • Recovery and rebalancing generate heavy internal traffic, so a failed disk can degrade client latency across the cluster unless backfill is throttled correctly beforehand.
  • Upgrades must follow a strict daemon order across monitors, managers, OSDs and gateways, and a mistake in that order on a live cluster is difficult to reverse.
  • Because it is self hosted, every byte served to the internet is transit you pay for on your own links, so the free licence does not mean free egress and bandwidth planning becomes your problem rather than the providers.

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 Ceph or Clonezilla better?
Neither clearly leads. Ceph 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, Ceph or Clonezilla?
Ceph starts at Free and Clonezilla at Free.
Does Ceph or Clonezilla run on more platforms?
Ceph runs on Linux. Clonezilla runs on Linux, Windows.
Can I use Ceph for free?
Both have a free tier, so you can try either at no cost before committing.
What is Ceph best used for?
Ceph is most often used for backing a private cloud where virtual machine disks, shared filesystems and an s3 endpoint all need the same hardware, growing past the point where a proprietary array upgrade costs more than a rack of commodity servers, research and media environments with petabytes of data and staff who can operate storage, providing an s3 endpoint on premises with multi site replication under your own control. Of those, backing a private cloud where virtual machine disks, shared filesystems and an s3 endpoint all need the same hardware and growing past the point where a proprietary array upgrade costs more than a rack of commodity servers are not what Clonezilla is typically brought in for.
What can Ceph do that Clonezilla cannot?
Ceph covers RADOS object store, RADOS Gateway, RBD block devices, CephFS. Clonezilla covers Disk/partition imaging, Disk cloning, Multicast deployment, Multiple file systems.

Answered from the vendors’ own pages

Ceph: How many nodes do I need to start?

Three is the practical minimum for a replicated cluster with real fault tolerance, and most production advice starts at five once you account for maintenance windows.

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
Ceph: Is it faster than a SAN?

Not on single stream latency. It wins on aggregate throughput and on growing without a forklift upgrade, which is a different property from raw speed.

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
Ceph: Can I buy support?

Yes. IBM sells IBM Storage Ceph and SUSE and others have offered supported builds; the upstream project itself is free.

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.

Ceph: Should I use it just for S3?

If object is all you need, a dedicated object store is simpler to run. Ceph earns its complexity when you need block and file as well.
