Obstor vs Synology Photos

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.

Synology Photos is a photo and video management service in DSM for browsing, organizing, searching, sharing, uploading, and previewing media. It requires a Synology NAS for private photo storage, and its mobile app can back up photos and videos to that NAS automatically. Users can share individual items or albums through links with passwords or expiration dates. Shared Space lets selected users collaborate, with access and editing rights assigned by folder. Organization tools include custom and conditional albums, automatic grouping, and facial and object recognition on supported NAS models. RAW files are supported; previews for HEIC/HEVC files and compressed videos require Synology Image Assistant. Mobile apps require iOS 16 or later or Android 11 or later; TV apps support Apple TV and Android TV. Chrome and Safari are recommended for web use. Synology Photos is free, with no paid premium tiers listed.
