Obstor vs Peer Global File Service

Obstor is an Apache 2.0-licensed, S3-compatible object storage server with built-in SFTP support. It works with S3 SDKs, command-line tools, and applications without code changes. In distributed deployments, objects are sharded and replicated across connected nodes, with each object kept in at least two global locations. Its native SFTP server stores uploaded files as S3 objects. Data features include SSE-C and SSE-S3 server-side encryption with KMS integration, configurable erasure coding for drive and node failures, and object versioning with lifecycle policies. IAM controls use users, groups, policies, and service accounts with S3 and AWS IAM policy syntax. Event notifications can be sent to Kafka, NATS, AMQP, Redis, PostgreSQL, Elasticsearch, and webhooks. Installation options include a single binary, Docker, a Kubernetes Helm chart, or building from source. Standalone instructions cover macOS, GNU/Linux, and 64-bit Windows. Standalone servers are intended for development and evaluation; versioning, object locking, and bucket replication require distributed deployment with erasure coding.

Peer Global File Service (PeerGFS) replicates, manages, and synchronizes files across sites, platforms, clouds, and storage systems. It sends changes in real time for active-active file sharing, uses distributed file locking to help prevent conflicts, and transfers changed data rather than whole files through delta-level replication. The product supports SMB and NFS workloads and lists Windows and Linux file servers, NetApp, Nutanix Files, Dell systems, and cloud targets including S3 and Azure Blob. Microsoft DFS Namespaces can unify SMB access across sites and support failover and failback. Security descriptions include SSL-encrypted traffic up to AES-256, role-based controls through Active Directory, and monitoring for suspicious file activity. The product also lists local caching, edge synchronization, metadata and access preservation, cutover orchestration, and migration reporting. Capabilities depend on configuration: edge caching is limited to Windows file servers, and NFS supports only replication and synchronization jobs. Pricing is available on request. A trial request includes a guided proof of concept with the pre-sales team. Peer Software says it began in 1993.
