Creating a SnapSync Job from a Remote NAS

  1. Go to Storage & Snapshots > Snapshot Backup > SnapSync.
  2. Click Create a SnapSync Job.
  3. Click Sync from Remote.

    The Create a SnapSync Job wizard opens.

  4. Specify a job name.

    The name cannot contain any of the following special characters: ` * = + [ ] \ | ; : ' " , < > / ? %

  5. Select the source remote NAS.
  6. Optional: Specify the remote SnapSync port number.

    The default is 8080.

  7. Specify an administrator account and password of the remote NAS.

    For security reasons, QNAP does not recommend using the "admin" account.

  8. Click Connect.
  9. Select the source storage pool.
  10. Select the source shared folder or LUN.
    • Shared folders and LUNs created via Instant Clone cannot be used as a source for SnapSync jobs.

    • SnapSync does not currently support encrypted LUNs.

  11. Select the destination storage pool.
  12. Select the destination shared folder or LUN.

    All data in the shared folder will be deleted.

  13. Optional: Click New to create a new destination shared folder.
  14. Click Continue on Remote NAS.

    The SnapSync wizard opens on the remote NAS.

  15. Select a backup plan.

    Backup Plan



    SnapSync backs up data periodically, according to a schedule.

    You can set the schedule to daily, weekly, or monthly. On the day the job runs, you can set the job to run once or periodically.


    Each write operation to local storage is immediately replicated to the destination storage pool.


    The job only runs when you start it manually.

  16. Configure settings for the destination NAS.

    The destination NAS is the NAS you started creating this job on.

    1. Specify the remote SnapSync port number.

      The default is 8080.

    2. Enter the remote NAS admin username and password.
    3. Click Connect.

      If prompted, complete 2-step verification. This is required if the destination NAS has enabled 2-step verification.

    4. Select the destination storage pool.
    5. Select the destination shared folder or LUN.

      All data in the shared folder will be deleted.

  17. Optional: Configure job options.




    SnapSync compresses the data before sending it to the destination. The destination NAS decompresses the data before saving it to disk. Enabling this setting can reduce transfer times if your NAS or the remote NAS has a slow network connection, or the two NAS devices are connecting via WAN.


    SnapSync reduces the amount of storage and bandwidth needed by eliminating duplicate copies of repeated data.


    SnapSync encrypts the data during transmission to the destination NAS. The data is then decrypted before being stored at the destination.

    Support application consistent snapshots

    SnapSync creates application consistent snapshots.


    This option is only available for VMware vCenter and Volume Shadow Copy Service (VSS) aware applications running on a Windows server. You must install QNAP Snapshot Agent on the iSCSI initiator.

  18. Click Next.
  19. Set the source and destination network adapters for this job.

    Adapter Setting


    Auto-Select Network Adapter

    QuTS hero automatically selects the fastest network adapters at the source and destination for this job.

    If either network adapter becomes disconnected, QuTS hero will select the fastest available adapter.

    Manual-Select Network Adapter

    Manually select the network adapters at the source and destination for this job. You can also select failover adapters, which the job uses if the either primary adapter becomes disconnected.


    The adapter lists are automatically filtered to only display adapters that can connect to the currently selected adapter.

  20. Click Next.
  21. Configure the latency monitor.
    • This setting is only available for real-time SnapSync jobs.

    • Latency Monitor monitors the latency of the SnapSync job to ensure the job is running normally. If the job latency goes over the threshold six times within a minute, QuTS hero issues a warning notification.

    1. Enable Latency threshold.
    2. Set a threshold value, in milliseconds. The value must be 1–5000.

      To determine the threshold value, run a SnapSync performance test by clicking Create a Performance Test. To view the average latency in previous performance tests, click Performance Report.

  22. Click Next.
  23. Optional: Select Execute backup immediately.

    When selected, the job will run immediately after it has been created.

  24. Click Create.
