Longhorn vs Synology Photos

Longhorn is a free, open-source distributed block storage system for Kubernetes. It replicates storage across nodes and data centers to increase availability, with V1 replicated, V2 replicated and V2 sharded with erasure coding volume types. Teams can schedule recurring snapshots and backups to NFS or S3-compatible secondary storage, and create disaster recovery volumes for recovery in a second Kubernetes cluster. A GUI dashboard is included, and the management UI is described as free. The software stack can be upgraded without disrupting running storage volumes. Installation options include kubectl, Helm, Fleet, Flux and ArgoCD. Longhorn supports mTLS for securing and encrypting gRPC communication between its control and data planes, but mTLS is disabled by default. Components need root access with privileged permissions for volume operations and management. Backups require an NFSv4 client, while ReadWriteMany volumes require NFSv4.1. Longhorn runs on Linux and supports API, web and self-hosted use. It is a CNCF incubating project; SUSE Storage is described as a Longhorn-based distribution with additional support, security, lifecycle management and certified integrations.

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.
