SeaweedFS

What it does: SeaweedFS is a distributed storage system serving S3 objects, Iceberg tables, and POSIX files from one cluster.
Scale: The product page says it scales linearly from gigabytes to petabytes and supports billions of files.
Protocols: The cluster supports S3, POSIX mounts, HDFS-compatible access, an Iceberg REST catalog, and WebDAV.
Integrations: The built-in Iceberg catalog supports querying with Spark, Trino, Dremio, and DuckDB.
Recovery: Enterprise data recovery can restore deleted files from the Admin UI during a configurable retention window; the free 25 TB trial caps that window at one hour.
Point-in-time recovery: Enterprise can rewind a folder, bucket, or object to a chosen moment, including restoring deletes and reverting overwrites, with a preview before changes are applied.
Data protection: Enterprise automatically repairs missing or corrupted erasure-coding shards and periodically checks shards against checksums for silent corruption.
Storage efficiency: Enterprise customizable erasure coding can use a 20+4 ratio with 1.2× storage overhead, according to the maker’s feature page.
Single sign-on: Enterprise Admin UI supports OIDC sign-in and role mapping, with examples including Keycloak, Okta, Azure AD, and Microsoft ADFS.
Deployment: The deployment guide offers an official repository binary and the container image chrislusf/seaweedfs-enterprise.
Production license limit: Development and testing under 25 TB is free, while production deployments require a paid license regardless of size.
Support: Enterprise support is optional and purchased separately from the capacity license; published support channels and response targets vary by plan.
License expiry: If an Enterprise license expires, SeaweedFS says it falls back to the open-source implementation and data remains accessible, while self-healing features are disabled.
