  • Optimizes data transfer to C2 Storage by uploading only changed data
  • Stores frequently accessed cloud data in the local cache to reduce access latency. Please 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 create space for new data. Please 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
  • Implements cache throttling to intentionally slow the amount of data being written to the mounted Hybrid Share folder when the Btrfs volume is low on available capacity. Please note the that:
    • Read speed is unaffected
    • Write speed is throttled when the volume usage reaches 80%
    • Minimum write speed (128 KB/s) is applied when the volume usage reaches 95%
