The minio/minio GitHub repository was archived on April 25, 2026, months after the project’s maintainers declared maintenance mode and pointed users who need support toward the commercial AIStor product. If you run MinIO community edition in production, the software underneath your backup repositories, data lakes, and CI artifact stores now comes from a repository whose README says “THIS REPOSITORY IS NO LONGER MAINTAINED.” No new features, no compatibility updates, and no guaranteed security patches will land there.
This is a forcing function, not a crisis. Object storage does not stop serving GETs because a repo got archived. But the longer you wait, the more data you will have to move, on someone else’s deadline. This guide maps the replacement field by use case: commercially supported platforms for production backup targets and Object Lock immutability, and community projects that are fine for labs but not for anything an auditor will ask about.
What changed
The timeline matters because it shows a deliberate sequence. In October 2025 the community edition went source-only; the README still says “We will no longer provide pre-compiled binary releases for the community version.” On December 3, 2025 the README declared maintenance mode: “No new features, enhancements, or pull requests will be accepted,” and “Critical security fixes may be evaluated on a case-by-case basis.” The repository was archived on April 25, 2026, and the README now lists AIStor Free and AIStor Enterprise as the alternatives. MinIO the company is very much alive: it sells AIStor, which it pitches for “exascale AI and data lakehouse workloads.” What ended is the free, community-maintained MinIO server that many teams deployed.
The practical consequence: any community MinIO build you run today is frozen. No CVE response is guaranteed. No compatibility work will track changes in the S3 API, Veeam integration requirements, or Kubernetes releases. The takeaway for the meeting: MinIO didn’t die, the free ride did, and running archived storage software in an auditor-facing role has a short shelf life.
Why on-prem S3 matters now
Three workloads are driving on-prem S3-compatible object storage in 2026, and none of them tolerate an unsupported platform.
- Immutable backup repositories. Veeam and Commvault both build immutable backups on S3-compatible targets on S3 Object Lock: Veeam requires Object Lock and versioning on the bucket, and Commvault says it “uses Compliance mode with object lock on S3 Compatible.” An immutable repository that stops receiving security patches is a contradiction in terms. See the immutable backup storage comparison for how the major platforms implement Object Lock.
- AI data lakes. GPU clusters need local, high-throughput reads. If the GPUs run in the same AWS Region as the bucket, S3 data transfer is free: AWS’s S3 pricing page exempts “Data transferred from an Amazon S3 bucket to any AWS service(s) within the same AWS Region as the S3 bucket.” The math changes when the GPUs sit on-premises or in another cloud or Region: then every training epoch pulls the dataset out of S3 as metered transfer, and request charges apply either way. That is the case for keeping hot datasets on object storage next to on-prem GPUs.
- Egress avoidance and sovereignty. If restores, analytics reads, and AI pipelines running outside the cloud repeatedly pull the same data, on-prem capacity at a predictable cost per terabyte can beat metered data transfer out. Run the math against the backup storage cost-per-TB benchmarks before assuming the cloud is cheaper.
The break-even depends on how much of your dataset you re-read each month and where the readers sit. Price both sides with your own access logs rather than a generic ratio.
The replacement field at a glance
| Model | Sweet spot | Watch out for | |
|---|---|---|---|
| Scality ARTESCA | Software-defined, commercial; your hardware or Scality’s preconfigured hardware | Immutable backup targets, 20 TB to multi-PB | On the software route, you supply and manage the hardware |
| Cloudian HyperStore | Software or appliance, commercial | Mixed workloads, multi-tenant, exabyte-scale design | Heavier platform; real sizing and licensing conversation |
| Object First Ootbi | Turnkey appliance | Veeam-only immutable backup, 15-minute deployment claim | Not general-purpose S3; Veeam only by design |
| MinIO AIStor | Commercial successor to MinIO | AI and data-lake estates staying on MinIO tech | Free tier is single-node; multi-node tiers are priced on request |
| SeaweedFS / Garage / RustFS | Open source, community | Labs, dev/test, hobbyist self-hosting | You are the support organization |
Commercial platforms: Scality, Cloudian, Object First, AIStor
Scality ARTESCA
ARTESCA is Scality’s lighter-weight, security-focused object store, and it is the most direct commercial answer to the post-MinIO backup-target question. Scality says it scales “from a 20TB starting footprint to multi-petabyte clusters validated up to 8.5 PB” and is “certified across the eight leading backup ecosystems,” including Veeam and Commvault. The security posture is the pitch: S3 Object Lock with compliance mode and MFA-controlled admin, part of what Scality calls its CORE5 architecture. Where it is weaker: on the software route you own hardware selection and lifecycle (Scality also sells preconfigured hardware), and for exabyte-scale or heavy multi-tenancy Scality positions its RING product instead. Fit: mid-size to large enterprises that want a supported, hardened backup target without buying a closed appliance.
Cloudian HyperStore
Cloudian builds S3-compatible storage for on-prem deployment and claims “the industry’s highest S3 API compatibility”, a real consideration if applications, not just backup software, will hit the endpoint. HyperStore runs on Cloudian appliances or servers you choose, grows by adding nodes toward what Cloudian calls “Exabyte Scale,” and builds in multi-tenancy, per-tenant QoS controls, and per-user metering “for chargeback or billing,” which suits service providers. Cloudian has also leaned into the AI story, including NVIDIA GPUDirect support. The trade-offs: it is a bigger platform with more operational surface than an appliance, and list prices are not published on the HyperStore page. Fit: large enterprises and providers consolidating backup, archive, and data-lake workloads onto one namespace.
Object First Ootbi
Ootbi is a turnkey immutable-backup appliance from Object First, a company TechTarget reported was “created by Veeam co-founders Ratmir Timashev and Andrei Baronov,” and it is built solely for Veeam. It is the shortest path from purchase order to hardened repository: rack it, connect it to Veeam, and the storage is immutable out of the box, with the vendor claiming “15 minutes to deploy and scale” and “No security expertise required.” That focus is also its boundary: Ootbi is not a general-purpose S3 endpoint for applications or AI pipelines, and a cluster tops out at four nodes, with multiple clusters used to scale beyond 7 PB. Fit: Veeam shops that want immutability now and would rather buy an outcome than operate a platform. If that is you, the ARTESCA-versus-Ootbi decision is the one to study closely.
MinIO AIStor
Staying with MinIO commercially is a legitimate option, and for some estates the right one. AIStor is the supported successor, which MinIO describes as “fully-S3-compatible object storage deployable anywhere across edge, core, and cloud environments.” The tiers matter: AIStor Free is a “Full-featured, single-node deployment” with community Slack and documentation support; Enterprise Lite is for teams that can self-support “with capacity requirements below 400 TiB”; Enterprise adds 24/7/365 direct-to-engineer support. MinIO does not publish prices for the paid tiers. If you are running hundreds of terabytes to petabytes of AI data on MinIO today, get an AIStor quote and compare it honestly against a migration project: moving petabytes is never free either.
Community options for labs
Three open-source projects come up most often as replacements. SeaweedFS (Apache 2.0, written in Go) describes itself as a distributed storage system for S3 object storage, file systems, and Iceberg tables. Garage (AGPLv3, Rust) targets “small self-hosted geo-distributed deployments” and lets you “Build a cluster with whatever second-hand machines are available.” RustFS (Apache 2.0, Rust) says it “combines the simplicity of MinIO with the memory safety and raw performance of Rust” and publishes its own RustFS-versus-MinIO performance comparison, but it is young: version 1.0.0 shipped in September 2026, so treat the claims as unproven until you benchmark them yourself.
The line to hold: none of these belongs in a compliance-facing immutability role without a support contract behind it. When the auditor or the cyber-insurance underwriter asks who patches your backup repository, “a GitHub community” is the wrong answer. Labs, dev/test, CI caches: fine. Production backup targets: no.
What to do about it
- Inventory every MinIO endpoint. It hides in CI systems, Kubernetes operators, and inside other products’ firmware. You cannot plan a migration you have not scoped.
- Classify by role. Compliance and immutability workloads migrate first; internal labs can wait or move to community options.
- Shortlist by use case, not by feature grid. Veeam-only: Ootbi versus ARTESCA. Mixed multi-petabyte: Cloudian versus ARTESCA versus Ceph RGW if you have the ops muscle. Kubernetes-heavy estates should start with the Kubernetes backup buyer’s guide first, because the backup platform choice constrains the storage choice.
- Test the S3 dialect with real workloads. Versioning, Object Lock in compliance mode, multipart uploads, presigned URLs, and IAM-style policies are where “S3-compatible” claims break.
- Set a hard deadline. Do not carry archived software past your next penetration test or cyber-insurance renewal. That is the date an unsupported MinIO becomes a written finding.
The one-line version for the steering committee: MinIO’s archival turned a free dependency into unfunded risk, and the fix is picking a supported platform per workload before the next audit cycle. Hunting for the single perfect MinIO clone is the wrong project.
Frequently asked questions
Is MinIO still safe to use in production?
It runs, but the community repository is archived and its README says it is no longer maintained, so there are no guaranteed security patches and no compatibility updates. For internal, low-stakes workloads that is tolerable short-term. For backup repositories, compliance data, or anything internet-adjacent, plan a migration against a fixed deadline.
Which MinIO alternative fits enterprise backup?
For Veeam-only environments, Object First Ootbi is the most direct supported path to an immutable repository. For a general-purpose hardened target that also serves other backup software, Scality ARTESCA is the strongest like-for-like candidate. Cloudian HyperStore wins when one platform must carry backup plus application and AI workloads at scale.
Is MinIO AIStor free?
Partly. AIStor Free is a full-featured, single-node edition offered free of charge, with community Slack and documentation support only. Multi-node deployments need Enterprise Lite (for capacity below 400 TiB) or Enterprise, and MinIO prices those on request.
Can Ceph replace MinIO?
Yes. Ceph’s RADOS Gateway implements the S3 Object Lock API, and commercial support exists through IBM Storage Ceph, which IBM says offers “high fidelity to AWS services like IAM, SSE, and Object Lock.” The cost is operational complexity: Ceph rewards teams with dedicated storage engineering and punishes those without it.
Does Veeam require Object Lock for immutable backups to object storage?
Yes. Veeam’s immutability for S3-compatible repositories uses Object Lock and versioning, and Veeam says to enable both on the bucket and leave default retention off. Veeam also runs a Veeam Ready program that “validates partner solutions,” so check your candidate platform’s status before you buy.
