Instead of Obstor
Obstor alternatives
Obstor is a free, self-hosted object storage server for S3-based workloads. It accepts S3 SDKs, command-line tools, and applications without code changes, and its native SFTP service stores uploads as S3 objects. In distributed deployments, objects are sharded and replicated across connected nodes, with each object stored in at least two global locations. Obstor also offers encryption, configurable erasure coding, versioning, IAM controls, and notifications to messaging systems and webhooks.

Other products may be a better fit when you need photo workflows on a Synology NAS, POSIX files, Kubernetes volumes, or an object service that grows without provisioning storage. Obstor is free under Apache 2.0 and supports Linux, macOS, Windows, web, and API use. Its standalone servers are intended for development and evaluation; versioning, object locking, and bucket replication require distributed deployment with erasure coding. Before switching, weigh the storage type and protocols your workloads require, the deployment environment, and how replication and recovery should work.
