To use rsync directly you would need to be able to run it on the NAS unit as well as the local station. &nbsp;There are some NAS that do have rsync built in.<br />

It can be used to copy from a local system to shared drive mounted on the local system though I suspect this will negate much of the benefit of the delta copying on bandwidth usage.<br />

delta copy for rsync

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.
