Title: Synchronising folders with another NAS? (not just backing up)
Post by: r00x on February 15, 2013, 04:04:57 PM

Hi, I have a DNS-320 with a few folders like 'movies' and 'documents' which I want to synchronise with identical folders on another NAS (in this case a Netgear Readynas NV+).

I would like to achieve a setup such that changes to the contents of either NAS gets synchronised with the other.

As far as I can see, I can only achieve "one-way" sync from the DNS-320 to the Readynas via rsync. I'm currently testing this and it is working, but if the contents of the Readynas folder(s) change I want them to be sync'd back in the other direction.

What to do? How can I achieve this? Both NAS devices seem to support rsync to some degree, but it seems easier to get the DNS-320 to connect to the Readynas than the other way round.

I've currently got the Rsync service enabled on the Readynas with a working username/password that I can log in with from the DNS-320 (this is what I'm using). I have to use "Nas-to-Linux" in the backup application as "NAS-to-NAS" fails with:

Code: [Select]

SSH Test Result : Failed ( Unknown Reason Failed )

RSYNC Test Result : Failed ( RSYNC Test Failed )
I've also got the "Enable remote backup service" box ticked in Remote Backups > Server in the DNS-320, but cannot get the Readynas to connect successfully this way.

Is synchronisation even a feature these are capable of or is one-way backup the only option?

A word of caution concerning what you want to do.  If you delete a file on the Readynas do you actually want it deleted from the DNS-320?

Having said that, have a look at installing funplug and its rsync implementation.
