how do I configure a second NAS as a snapshot repository on Qnap

Creating a Snapshot Replica Job


When running a Snapshot Replica job for the first time, all data on the volume or LUN is transferred to the destination NAS. This may take a long time, depending on the network connection speed and the read/write speeds of both NAS devices.

  1. Go to Main Menu > Storage & Snapshots > Snapshot Backup > Snapshot Replica.
  2. Click Create a Replication Job.

    The Create a Snapshot Replication Job wizard opens.

  3. Select the source volume or LUN.
  4. Optional: Specify a job name.

    The default job name is the first 6 characters of the source volume or LUN name followed by “_rep”.

  5. Click Next.
  6. Specify the IP address of the destination NAS.

    Perform one of the following actions.


    Destination NAS Location


    Manually specify the NAS address

    LAN, WAN, Internet

    You can enter an IP address, hostname, or FQDN.

    Click Detect and then select a NAS from the list


    QTS displays a list of all QNAP NAS devices on the local network. You can sort the list by hostname or IP address.

    Click Local Host


    Choose this option to replicate snapshots between different storage pools on the same NAS.

  7. Enter the password for the default admin account on the destination NAS.
  8. Optional: Specify a port.

    The default port is 22.

  9. Click Test.

    QTS connects to the destination NAS using the specified admin password, and then checks that there is sufficient space at the destination to store the source volume or LUN.

  10. Click Next.
  11. Specify how many replicated snapshots will be kept on the destination NAS.

    After the specified number is reached, the QTS will delete the oldest snapshot each time it replicates a new snapshot.

  12. Select the destination storage pool.
  13. Select a backup plan.

    Backup Plan


    Start replication job after taking a local snapshot

    The replica job will run each time QTS creates the specified number of snapshots. These snapshots may be created manually or on a schedule.

    Start replication job on a schedule

    The replica job replicates all snapshots created since it was last run. If no new snapshots were created, it will not replicate any data.

    Choose one of the following scheduling options:

    • Run on a schedule: The job automatically runs daily, weekly, or monthly. Settings:

      • Schedule: How often the job runs

      • Day: The day that the job runs on

      • Expiration date: The replica job stops running after this date

      • Frequency: How often the job runs on the days specified by “Schedule” and “Day”

      • Start at: The time that the job starts running.

    • Run once: The job runs once on a specific time and day.
    • Manually start: The job does not run unless a user starts it.

    Take a new snapshot on a schedule, then run replication job

    The job runs daily, weekly, or monthly. QTS takes a new snapshot immediately before starting the job. This ensures that there is always at least one snapshot to replicate.

  14. Click Next.
  15. Optional: Configure transfer settings.



    Encrypt transfer

    QTS encrypts the snapshot before sending it.

    • The job must be run by the NAS admin user

    • The port used by this job must be the same as the SSH port on the destination NAS

    Compress transfer

    QTS will compress snapshots when replicating them. This consumes more CPU and system memory, but reduces the amount of bandwidth required.


    Enable this setting in low bandwidth networks, or if the NAS devices are connected through a WAN.

    Maximum transfer speed

    Limit how much network bandwidth this job uses.

  16. Export the source data to an external storage device.

    To save time and bandwidth, you can export the source data to a connected external storage device such as a USB disk. After connecting the external storage device to the destination NAS, QTS will import the source data when the job is next run.

  17. Click Next.
  18. Optional: Select Execute backup immediately.

    When enabled, the job will run immediately after being created.

  19. Review the job information.
  20. Click Finish.

Snapshot Vault

After setting a NAS as the destination for a Snapshot Replica job, the replicated snapshots are stored in Snapshot Vault. Each replica job has its own separate vault.


Cloning a Volume from a Remote Snapshot


The time required to clone the volume depends on the amount of data stored on the volume and the connection speed between the two NAS devices.

  1. Go to Main Menu > Storage & Snapshots > Storage > Storage/Snapshots.
  2. Select a thick or thin volume.

    The volume must have at least one snapshot.

  3. Select Snapshot > Snapshot Manager.

    The Snapshot Manager window opens.

  4. Under Select snapshot location, select a remote NAS.
  5. Select a snapshot.
  6. Click Clone.

    The Clone Snapshot window opens.

  7. Specify a volume alias.
  8. Select a storage pool.
  9. Select Enable encryption during transfer.

    QTS encrypts the snapshot before sending it for additional security.

  10. Click OK.

QTS clones the volume and shared folders, and then displays a confirmation message.
