Remote Sync

Remote Sync (Rsync) can allow your NAS to be used as a backup destination or backup source. When using your NAS as a backup source, you can choose to back up the data from your NAS onto another remote ASUSTOR NAS or Rsync compatible server. When your NAS acts as a backup destination, you can back up the data from another remote ASUSTOR NAS or Rsync compatible server onto your NAS.

If you wish to use Remote Sync while using your NAS in conjunction with another remote ASUSTOR NAS, please remember to enable the Rsync server feature on the remote NAS (Services Rsync Server).

  • Use encrypted transmission: If you choose to use encrypted transmission, you will have to enter the other host's SSH connection information in addition to your Rsync account information.
  • Select a backup type here.
    • Back up multiple items to a singular location: All chosen source folders will be copied one by one to the destination folder. Multiple folders can be selected.
    • One on one folder backup: All data in the designated destination folder will be synchronized with the data in your source folder. The contents of both folders will be identical.
      • Select multiple 1 on 1 folders for backup in one backup job here. (New to ADM 4.2.1)
      • Keep extra files at the destination: Once the copying and synchronization of files is completed, the data at the source and destination should be exactly the same. However, sometimes there are extra files present at the destination. These files are only present at the destination but not at the source. By enabling this option, these extra files will be kept at the destination and will remain untouched.
  • Here you can set the frequency of repeated backups during the backup period. (New to ADM 4.2.1)
  • Archive mode (incremental backup): After enabling this feature, successive backup jobs (after your first backup job) will only copy the data that has changed since your last backup job (block level). For example, if you have made some small changes to a 10 MB file, incremental backup will only copy the portions that you have made changes to. This can significantly reduce bandwidth usage.
  • Compress data during the transfer: During backup you can compress the data that is being transferred thereby lowering bandwidth usage.
  • Keep file metadata: When you enable this option, certain file properties (permissions, extensions, attributes, owner, groups, etc.) will be sent along with the file to the destination.
  • Support sparse files replication: You will only need to enable this option when the data that you wish to back up contains sparse files. Normally, you will not have to enable this option.
  • Resume file transfer: When a connection or transfer is interrupted, enable this option to continue transferring files when the connection is restored.
  • Mission Mode: Sometimes backup jobs may be stopped because of various connection problems with a busy server on the other end. ASUSTOR’s Mission Mode option allows you to configure the number of connection attempts and time interval for connection attempts, ensuring for the successful completion of your backup job. This also gives IT administrators a significant amount of flexibility when configuring backup jobs.
