dedicating 2nd ethernet port for backups.. how?
Using a pair of 516's (or any two readynas devices with dual ethernet), is there a way to use the second ethernet port for a direct connect to the second NAS for only backups? For example, I have t...
As long as the two interfaces of the two NAS are on the same IP range, and that this IP range is different from the normal IP range (otherwise you may have problems because the NAS doesn't know where to send the data), then they should be able to communicate. There was a time where you had to use a crossover cable to do it, nowadays the network cards do this job for you and any network cable should do the trick as long as it is a cat 5E or better (otherwise you won't have gigabit speed).
So the simplest way is to use static IP indeed. By default the interfaces would get APIPA addresses if no DHCP is found but this is not a best practice to use those (even though this should work). You can also set a DHCP server on one of the devices if you want but that's just not useful.
Once you get those IP set, you can use any direct backup method you want. This includes smb, FTP or rsync for example.
