1. Which would be the best way to connect my BACKUP NAS?
a) By also connecting it to the router via GBit Ethernet port (DATA NAS----GBit/Eth-----Router-----GBit/Eth-----BACKUP NAS)
b) Wirelessly (is it possible? Latency would be probably an issue...)
c) Directly to the DATA NAS via GBit Ethernet port using crossed cable? (Router------GBit/Eth------DATA NAS-----GBit/Eth X------BACKUP NAS)
d) Directly to the DATA NAS via eSATA port? (Router------GBit/Eth------DATA NAS-----eSATA------BACKUP NAS)
e) None of the above... :( |
(a)

| 2. If I choose RAID6 for DATA NAS with 4x4Tb HDDs, in the future, is it possible to install a 5th or 6th HDD on the fly... so that RAID6 automatically rebuilds the array now adding 2 new disks and also without the need to connect a BACKUP NAS to manouevre data on the rebuilding process? |
yes

| 3. How complicated (or easy, depending on your point of view) is it to configure RAID6 (DATA NAS) and JBOD (BACKUP NAS)? |
Both are fairly easy to set up. jbod is one mode of flexraid, so there are more options there.

| 4. If I choose RAID6 for DATA NAS with 4x4TB disks, I would have a total net amount of 8Tb of space. In this case, is it enough to have just 2x4Tb disks (JBOD) on my BACKUP NAS or should I install the exact same physical amount, independently of logical amount (net anount of space)? |
2x4TB should be enough. Keep in mind that you need to balance the storage manually. For instance, if you have a 6 TB share on the main nas, there is no way to back it up on one of the 4TB volumes on the backup. So you do need to manage your share sizes so you can allocate them to backup volumes.

| 5. In terms of I/O, 4Tb on a single HDD sound for me like "too big" for a fast throughtput/performance. Would it be better to use 3Tb or even 2Tb HDDs instead? |
No.

| 6. In addition, how can I map BACKUP NAS (JBOD) to get data from DATA NAS (RAID6). ReadyNAS comes "from factory" with this feature or should I install some software like SyncBack Free? |
The built in backup whould work fine.

| 7. I surely won't be using RAID on my BACKUP NAS. JBOD sound like the way to go, but are there any other reliable options or JBOD is really the best pick? |
In my opinion jbod is fine for backup. Raid is more reliable though, and it is a bit simpler if you only have one volume to worry about.

| 8. I've read something about Synology (DS1513+ or DS1812+) and QNAP (TS-670). Is Netgear ReadyNAS really the best pick? Would they fit/work/perform nearly the same for my needs or is there any better candidate? |
This is a Netgear forum :D You can take a look at the various UIs here:
