Rsync between two ReadyNAS Duo units
Hello,
I have two ReadyNAS Duo units, each of them provided by two 1 TB HDD in XRAID. One unit (named in the network as "NAS") is currently used as a remote disc for my job, so it has a certain amount of data, which I don't want to loose. The other unit (named as "NAS_BKUP") is empty of data. Both the units lay under the same LAN segment.
My question is: if I enable Rsync on both the units, I will loose my data from the first unit? Is there a quick beginner's list of DOs and DONTs to setup Rsync succesfully?
Thank you in advance.

No. It's just another protocol as far as the NAS is concerned.
Details on setting up rsync depends on the firmware you are running - can you let us know what both duos are using?
Also, I am thinking your goal is to set up rsync backup (perhaps on a schedule). Is that correct?
Thank you, Stephen,
The unit called "NAS" is a ReadyNAS Duo with S/N 1VB384RK015FD, firmware RAIDiator 4.1.14 [1.00a043]. At now, it is used at 9% of 1 TB
The unit called "NAS_BKUP" is a ReadyNAS Duo with S/N 24M30B7G001BF, firmware RAIDiator 4.1.14 [1.00a043]. At now, it is fully available.
My goal is to have a full-time working and synchronized copy of the whole content of the "NAS". I use this unit as "file server" of my office, available to all the users (me and my two collaborators). At now, I didn't feel the need of a backup copy (I have two mirroring disks in the unit!), but...
Recently, a strange issue occurred - two times - to the "NAS" unit (no more on-line in the LAN, powered-on but not responding at all, even by pressing the power on/off button to turn it off).
To avoide a disaster, I should like to have a second mirroring unit, which is on-line all the time with the same content of the first unit. This should avoid downtime to my office, needed to move the two disks from one unit to the other (assumed that this scenario should be safe for my data).
Is this purpose of mine in the possibility of the Rsync protocol? Could I obtain a "real-time" backup service between the two units, while I'm normally using my file server (opening/moving/deleting files)?
Thanks in advance.

You should have a backup of the NAS, as RAID is not enough to keep the data safe.
Rsync backup can copy your shares from NAS to NAS_BKUP on a schedule. It is not continuous, but it can be as often as once per hour.
The overall process is in the manual (chapter 6): http://www.downloads.netgear.com/files/GDC/RND2110/RAIDiator4-1_SW_en_06Dec11.pdf
There's an old guide specific to rsync which is still basically accurate but the UI look and feel is older than what you have: http://www.readynas.com/download/documentation/support/rsync_howto_nastonas.pdf
