Is Ceph or Zerto better?

Neither clearly leads. Ceph starts at Free and Zerto at $5/month, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.

Which is cheaper, Ceph or Zerto?

Ceph has a free tier; the other does not. Paid plans start at Free for Ceph and $5/month for Zerto.

Does Ceph or Zerto run on more platforms?

Ceph runs on Linux. Zerto runs on Windows, Linux, Web.

Can I use Ceph for free?

Yes. Ceph has a free tier, so you can try it without paying. Zerto starts at $5/month.

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 Zerto is typically brought in for.

What can Ceph do that Zerto cannot?

Ceph covers RADOS object store, RADOS Gateway, RBD block devices, CephFS. Zerto covers Continuous data protection, Journal-based recovery, Automated failover, Non-disruptive testing.

The short version

Only Ceph has a free tier, so it costs nothing to try first.
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.; Zerto zerto with Azure is listed on UK G-Cloud as a reseller-managed disaster recovery service, not Zerto's own licence pricing, with OS management from £75 per host per month for the public sector
They diverge on capability: Ceph covers RADOS object store, Zerto covers Continuous data protection.

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.

Zerto

Zerto with Azure is listed on UK G-Cloud as a reseller-managed disaster recovery service, not Zerto's own licence pricing, with OS management from £75 per host per month for the public sector

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.

Zerto: Can I try Zerto before buying?

Yes, Zerto offers a 14-day free trial or on-demand lab access to test the platform.

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.

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.

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.
