Comprehensive syncing available on Windows systems thanks to Rsync and DeltaCopy
Bookmark and Share

08/05/2014- Many backup solutions are available for those seeking peace of mind in the digital world, though a number of options turn out to be complex, expensive, or needing to be imported from third-parties (such as OwnCloud and Syncrify). But why reinvent the wheel when a free and reliable solution is ready and waiting on your Thecus?


For numerous forms of backup, all Thecus NAS already have a native engine embedded. Named “Rsync Target”, this comprehensive tool can be found in the Backup menu inside the system administration interface (ThecusOS). By enabling the Rsync Target Server option and setting a username and password, your NAS will be able to receive any data from a Rsync Client over the LAN or WAN. Just don't forget to open port 873 on your router.

Please note: Rsync is available on all OS5 and OS6 Thecus NAS systems


Let's say you have to back up one file every night. A normal file copy operation would copy the entire file even if only a few bytes have changed. DeltaCopy[1], on the other hand, would only copy the part of file that has actually been modified. This reduces the data transfer to just a small fraction of the 500 MB total, saving you time and network bandwidth. 

Once installed on any Microsoft desktop or server, DeltaCopy will allow you to connect to your Thecus NAS and perform various backup/sync tasks. Just set and forget it.

DeltaCopy Highlights: 

  • Incremental backup – Copies the parts of the file that have been modified rather than the whole file
  • Task Scheduler – Profiles in DeltaCopy can run based on a schedule
  • Email Notification – Administrators can receive email confirmation related to successful and failed transfers
  • One-Click Restore – Backed-up files can be easily restored.
