Creating a NAS to NAS Backup Job

  1. Go to Backup Station > Remote Replication > NAS to NAS.
  2. Click Create a Replication Job.
  3. Specify a job name.
  4. Configure the remote server.
    1. Click Settings.
    2. Configure the following remote site settings.

      Setting

      Description

      Name or IP address of the remote server

      The remote server DNS name or IP address.

      User name

      The username of the remote user. The user must have full read/write access and a sufficient quota limit on the remote server.

      Password

      The password of the remote user.

      Port Number

      The Rsync port of the remote server. The default is 873.

      Enable encryption

      Transfers are encrypted for additional security. SSH connections must be enabled on the remote server and the remote user must have permission to perform SSH encrypted backup jobs.

      Port number: The SSH port of the remote server .
    3. Optional: Test the remote server connection.
    4. Click Apply.
  5. Select the source folder.

    The source folder is a local shared folder or subfolder.

  6. Select the destination folder.

    The destination folder is a shared folder or subfolder on the remote server.

  7. Click Add.
  8. Configure the following settings.

    Setting

    Description

    Activate file compression

    QES 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 have slow network connections, or are connecting via a WAN.

    Perform incremental replication

    On the first run of a job, Rsync replicates all files to the remote server. On subsequent runs, Rsync only replicates files that have been modified since the last run.

    Tip:

    QNAP recommends enabling this setting, as it can greatly reduce backup times.

    Delete extra files on remote destination

    By default, Rsync only adds new files and updates modified files at the destination. Enabling this setting causes Rsync to delete files from the destination folder if they no longer exist in the source folder.

    Handle sparse files efficiently

    A sparse file is a type of computer file that contains large blocks of zero-byte data. Enabling this setting allows Rsync to replicate sparse files more quickly.

    Remove source files

    QES automatically deletes the source files from the source NAS after the job has run successfully.

    Replicate ACL and extended attributes

    Rsync replicates ACLs for Windows files and extended attributes for Mac and UNIX files.

    Important:

    QES and the remote server must have the same ACL features enabled and be joined to the same domain.

    Maximum transfer rate (KB/s)

    Limit the amount of bandwidth used by Rsync. By configuring this setting, you can prevent Rsync from consuming all bandwidth and affecting NAS storage performance. 0 is unrestricted.

    Check file contents

    By default, Rsync determines if two files in the source and destination are identical by comparing their filenames, last modified dates and file sizes. When this setting is enabled, Rsync also compares content of both files using checksums.

    Send alert emails when the following events occur

    You can receive an email alert each time a job fails or finishes successfully. The SMTP server must be configured in QES at Control Panel > System > Notification > E-mail > SMTP Server.
  9. Configure a job schedule.
    1. Click Backup frequency.
    2. Select Enable schedule.
    3. Specify the schedule.

      The job can be scheduled to run daily, weekly, monthly, or to repeat after a certain number of hours.

    4. Click Apply.
  10. Optional: Select Execute backup immediately.

    The job will run immediately after you finish creating the job. Subsequent runs will follow the backup schedule.

  11. Click Apply.

QES creates the job, and then runs it if you selected Execute backup immediately.
