Hybrid Share

Features

  • Hybrid cloud solution: integrates cloud storage with multi-site on-premises NAS, gathering stability, reliability, and flexibility for better collaboration of your workforce
  • Global file synchronization:
    • Allows mounting the same Hybrid Share folders on multiple NAS for seamless multi-site file access
    • Supports global file locking for data consistency in collaboration across locations
  • Data protection:
    • Supports restoring to a snapshot recovery point, protecting Hybrid Share folders from malicious attacks or accidental actions
    • Supports automatic DSM configuration backup and restoration for instant data recovery
  • Smart cache:
    • Centrally stores data on C2 Storage while caching frequently accessed data (or "hot data") on local NAS for low-latency performance, balancing the needs for saving local storage and network bandwidth
    • Supports pinning files and folders to the local cache of Hybrid Share folders
  • Centralized management:
    • Web-based C2 Storage portal for easy management of Hybrid Share folders and their connection to each NAS host
    • Detailed logs for monitoring and auditing file access activities
  • Military-grade encryption: ensures data security with end-to-end AES-256 encryption
  • Efficiency: optimizes data transfer to C2 Storage by uploading the changed data only

Specifications

  • Requires a Synology NAS model that supports the Btrfs file system, has 2 GB of memory, and is updated to DSM 7.0.1 or above
  • Requires a Synology Account with a subscription to the C2 Storage - Advanced Plan
    • Offers new subscribers a 30-day free trial without credit card information
    • Supports third-party login using Apple and Google
  • Maximum single file size: 768 GB
  • Maximum path name length: 4 KB (4,000 bytes)
  • Snapshot feature is supported on Hybrid Share 1.3.0 and above
    • Maximum number of retained snapshots: 32
      • Set a schedule to automatically take one snapshot within 24 hours
      • Manually take an unlimited number of snapshots within 24 hours
  • Logs and global file locking features are supported on Hybrid Share 1.4.0 and above
    • C2 Encryption Key is required to enable file transfer logs
  • Allows the same Hybrid Share folder to be mounted concurrently on up to 10 Synology NAS hosts
  • Allows a Synology NAS host to concurrently mount 5 to 30 Hybrid Share folders, depending on the hardware specifications of the NAS host
  • Only allows administrators (or users delegated with sufficient permissions) to mount a Hybrid Share folder or convert a shared folder to a Hybrid Share folder at DSM Control Panel > Shared Folder (Learn more)
  • Supports file access via the following protocols/packages:
    • SMB/CIFS
    • AFP
    • NFS
    • FTP
    • WebDAV
    • File Station
    • Synology Drive
  • Supports the following applications, packages, and services:
    • File Station: access and manage the contents of a Hybrid Share folder from DSM or DS file (mobile)
    • Synology Drive: access and manage the contents of a Hybrid Share folder with versioning and collaborating on Synology Office files
    • Hyper Backup: backs up and recovers Hybrid Share folders
    • Cloud Sync: sync and share files and folders to other supported cloud services
    • Web Station: set up web portals to manage files and folders
    • USB Copy: copy files and folders between a Synology NAS and external USB/SD storage devices
    • Presto File Server: transfer files and folders between multiple Synology NAS hosts, or between personal computers and Synology NAS
    • Synology Universal Search: search for files and folders by the names on a Synology NAS (Contents in Hybrid Share folders cannot be indexed)
    • Document/PDF Viewer: view documents and PDF files
    • Log Center: monitors and records file transfer activities on Synology NAS
    • Express Box: a physical file transfer service that bypasses connectivity limitations for initial deployments
      • The minimum storage requirement for the local NAS is the total size of the data to be migrated, plus the planned local cache capacity (at least 500 GB)
  • Stores frequently accessed cloud data in the local cache to reduce access latency. Note that:
    • The reserved local cache size must be at least 500 GB
    • The reserved local cache size cannot exceed 90% of the Btrfs volume size
    • The reserved local cache size cannot exceed the quota of the Hybrid Share folder on C2 Storage
  • Evicts data with the oldest access time from the local cache to make space for new data. Note that:
    • Oldest accessed data (excluding pinned files and folders) are evicted automatically when the local cache usage reaches the reserved local cache size
    • Users can also go to File Station to select and manually release local files from the local cache
  • Cache throttling mechanism slows down writing data to the mounted Hybrid Share folder when the Btrfs volume's capacity is running low. Note that:
    • Read speed is unaffected
    • Write speed is throttled when volume usage reaches 80% (for a volume smaller than 1 TB) or when volume space is less than 200 GB (for a volume larger than 1 TB)
    • Minimum write speed (128 KB/s) is applied when the volume usage reaches 95% (for a volume smaller than 1 TB) or when volume space is less than 50 GB (for a volume larger than 1 TB)
  • Synchronizes file privileges exclusively for domain users
  • Synchronizes permission inheritance and removal of inherited permissions (including local and domain users) for any subfolders across all NAS with the Hybrid Share folder mounted

Limitations
