The scheduled backup application works well but backups can collect all sorts of obsolete rubbish after a while. For my purposes, scheduled synchronisation would allow me to "mirror" an online DNS-323 with this DNS-320.
Thanks

Thanks but that's not what I am looking for. I have several synchronisation applications I can run from PCs.

The DNS-320  has, as one of its installed applications, a scheduled backup application. This works well as a backup but I would prefer to synchronise rather than back-up.

A PC application requires a PC to be "on" and transfers data from one NAS to the PC and then from the PC to the other NAS. A NAS application suits me much better.

As a matter of interest, am I the only one looking for this functionality?

I've been looking for this too, but I'm a absolute newbie to NAS and do not even manage  to set the shares, thus ...

If there is just the two of us I guess it won't happen. That's a pity as most of the logic is already there. I know, things are never that simple but it's a start.

The following thread describes an option for network mirroring: http://forums.dlink.com/index.php?topic=37897.0

Thanks for the response but I think that either that (referred to) post is incorrect or the DNS-320 manual is incorrect.

>> Perfectly possible. There are two options for network mirroring.
There are none in the manual.

>> Either setup a schedule for backups using…
That’s in the manual but that’s a backup not synchronisation.

>> …which utilizes RSYNC and encryption…
Rsync encapsulates a protocol for efficiently detecting file differences across a network and transmitting the differences necessary to make the files identical as deltas. This protocol can be used for backups (incremental or otherwise) or synchronisation.

If a folder (directory) is moved on the source drive, a backup will copy the moved folder to the destination where there will now be two copies; the original and the “moved”.
Synchronisation on the other hand will “move” the directory on the destination (even if it copies and then deletes the original).

I use backups for business and other records that have to be kept and I use synchronisation for music etc because I don’t want to keep old versions of the same track. In addition I have lots of scanned documents that get moved as they are catalogued.

Yes, I can use software on a PC to perform the synchronisation but this requires another “always on” PC, additional UPS load and double the network traffic. It would be better to drop the second NAS and just use the PC.
