MinIO: Open source S3-compatible object storage with no licence fee, if you can carry the operational burden yourself

S3-compatible on-premises object storage with object lock immutability
As of 1 September 2026, Cloudian's pricing is not published; the vendor quotes on request. Object storage you run in your own data centre with an S3 API, bought mainly so backups can be made immutable without sending data to a public cloud. Softwr lists it under File Storage. Cloudian is made by Cloudian, Inc., available on Linux.
Overview
Cloudian HyperStore is software-defined object storage deployed on commodity servers or as Cloudian appliances, presenting an S3-compatible API. It supports erasure coding across nodes and sites, multi-tenancy, and S3 Object Lock, which enforces write-once-read-many retention that even an administrator cannot override during the retention period. The object lock capability is the commercial driver. Ransomware operators routinely target backup repositories, and an immutable on-premises target defeats that, which is why Cloudian appears so often as the backup landing zone behind Veeam, Commvault, Rubrik and Veritas. Compared with public cloud object storage, the argument is total cost at scale and the absence of egress charges: restoring a hundred terabytes from your own array costs nothing, while restoring the same volume from a public cloud can cost more than a year of storing it. That asymmetry is the fact that changes shortlists, and it only appears during an incident. Buyers are enterprises, government agencies, universities and media organisations with multi-petabyte estates or data residency requirements. The trade-off is that you now operate storage. You buy, rack, patch and eventually refresh the hardware, and the operational headcount that a public cloud absorbs comes back onto your payroll.
The honest half
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Cloudian.
Cross-shopped
Each pairing was judged by two reviewers asking whether a buyer would genuinely weigh the two against each other. The ones that failed were deleted rather than published.

Answered, with sources
Each answer names the page it came from, so you can check it rather than take our word for it.
Within the retention period, yes, provided the lock is set in compliance mode. That is precisely why it is the common answer to backup-targeting ransomware.
No. That is the central cost argument against public cloud object storage, and it only becomes visible when you have to restore at volume.
Yes, HyperStore is software-defined and runs on qualified commodity hardware, or you can buy Cloudian appliances if you would rather not certify your own.

Softwr does not host reviews and shows no star rating for Cloudian, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it.
