      Encrypts data before sending it to the destination.

      This can reduce the risk of unauthorized data access.

      Warning:

      Client-side encryption cannot be disabled, and the password cannot be changed after encryption is applied.

      1. Select Use client-side encryption.

      2. Click Settings.

      Remove additional files in destination folder

      Removes destination data that does not exist in the source folder.

      Changes to files in the source folder will be mirrored in the destination folder.

      Integrate with QuWAN

      Allows QuWAN to manage and optimize this job’s network traffic.

      Detect sparse files

      Uploads only non-null data for sparse files.

      Check file contents

      Examines file contents, data, size, and name to determine if two files are identical.

      Important:

      Selecting this option may increase the time and bandwidth used when syncing data.

      Exclude duplicate files

      Examines file contents, data, size, and name to determine if files are duplicates.

      Duplicate files are excluded from the job.

      Exclude symbolic links

      Include hidden files and folders

      Includes all hidden files and folders.

      Compress files during transmission

      Compresses files to lower bandwidth requirements.

      This can speed up data transfer over a slow data connection, but consumes more CPU resources.

      Exclude system-generated temp files

      Excludes temporary files created by the system.

      Do not take a snapshot

      Reads data directly from the disk instead of using a snapshot as the backup source.

      Replicate ACL and extended attributes

      QTS and QuTS hero have incompatible ACL settings. If conflicts occur with backup, sync, and restore jobs between QTS and QuTS hero, Windows ACL takes priority.

      Important:

      To prevent NAS user accounts from having different access permissions, ensure the username and user ID match on both devices, or that both accounts are authenticated from the same AD/LDAP server.

      Compare file size and modification date during initial sync

      Compares the file size and modification date if the cloud server did not provide a checksum for the destination file.

      Source files with a different file size or more recent modification date are sent to the destination.
      Sync Qsync folders only

      Only Qsync folders are synced.

      Note:

      • This option is only available if the HBS 3 versions on both the source and destination NAS devices support Qsync.

      • This option allows you to back up Qsync folders to a NAS device or restore Qsync folders backed up on the same NAS device.
  15. Optional: Configure the job options.
    Note:

    Some options are only available with certain destination types.

      After exceeding this limit, real-time jobs enter a warning state and scheduled jobs are suspended.

      Concurrent file processing limit

      Specifies how many files to transmit at once.

      Tip:

      Processing files concurrently can improve the transmission rate, but uses more system resources. Use the default setting if you are unsure.

      Restart after abnormal termination

      Restarts the job if it abnormally terminates while running.
  16. Optional: Configure the network interface assignment.
    Note:
