Release notes

Important Note

  1. Active Backup for Business Agent (DSM) allows you to back up your Synology NAS's entire system. As the backup destination, Active Backup for Business must be installed on another Synology NAS.
  2. Compatibility limitations for the source and destination Synology NAS servers during system recovery:
    • System recovery can only be done if the destination NAS model is identical or a successor to that of the source NAS (e.g., DS 218+ can be restored on another DS218+ or DS220+).
    • The number of drives installed on the destination NAS should be more than or equal to that of the source NAS.
    • The drives on the destination NAS must be installed in the exact same slot positions as the source NAS.
    • The destination NAS must be comprised of drives of the same type. That is, the destination NAS cannot contain a mix of SSDs and HDDs.

What's New

  1. Full-system backup provides comprehensive protection for your Synology NAS, including user data, system configurations, and packages.
  2. File/folder level and full-system level restoration are provided for flexible recovery solutions in different scenarios.
  3. Block-level and incremental backup provides fast backup speed and efficient use of space. Change Block Tracking (CBT) technology intelligently tracks data changes to greatly reduce the time and computing resources needed for each backup task.
  4. Supports data deduplication to better utilize the space on the remote backup destination.
  5. Supports encrypted data transfer to protect data during backup and restorations.
