Notes:

  1. Synology C2 Storage for Hyper Backup requires Hyper Backup version 2.2.4-1213 or above. Synology does not guarantee compatibility with DSM or Synology C2 Storage for older versions of Hyper Backup. Synology C2 Storage is not supported in China.

  2. The fixed retention policy keeps 11 backup versions stored over 30 days. Only the size of the source data on Synology NAS counts towards your storage quota.

  3. While all backup versions count towards your storage quota, deduplication eliminates duplicate data across backup versions, saving a considerable amount of space.

  4. Hybrid Share is only available for DSM 7.0.1 and above. File and folder pinning is only available on DSM 7.0.1 and above.
