Recommended way to replicate/copy the contents of one readynas to another one that is offsite?
One is NS312 and the other is NS424. Both have 6.8.1 firmware. Both sides have 75/75 internet speeds. Is the Replicate feature the one to use or the ReadyDR? What amount of data can be moved in a...
Where is rsync over ssh accessed and setup?
Does ReadyDR require an open public-facing port, i.e. 5253?
Since the data comprises fulls+incr, can that chain be accessed if need be out of a snapshot?
I'd like to directly access the offsite image files in the event that the local nas can't perform it duties. If that is what is meant as "direct access".
Restoring snapshots requires extra storage on the nas or a third repository?

Yes. https://kb.netgear.com/31224/ReadyDR-FAQ
So does rsync over ssh.
You could use VPN routers at both sites to avoid that - if I understand your goal, you probably will need that them anyway when you switch to the backup NAS.

Yes. With Windows, you can right-click on a folder or file, and see the previous versions. You can also roll back from the web admin UI.

You need to restore a snapshot on the NAS where it was made. The storage implications are a bit tricky to explain. Please read this post, and then follow up here with questions: https://community.netgear.com/t5/ReadyNAS-in-Business/ReadyNAS-312-Need-Help-Understanding-Snapshots/m-p/936586/highlight/true#M3041
Which method is the fastest for moving data?
I haven't benchmarked ReadyDR. The real-world speeds will depend on the specific NAS models, the ISP speeds (nominally 75/75 in your case), but also the speed and latency on the path between the two sites.
ReadyDR moves the least amount of data for incremental backups, but that might not matter that much if you aren't backing up SQL databases or iSCSI LUNs.
Do you have a guestimate on the amount of data you need to move?
Approx. 100GB/day.
I am following the Backup job proc. here:
It seems to imply that only the folders that appear at the top of the tree (and what appears below them) can be individually backed up. Is that right?
In the following screenshot it says to place the key in ~/.ssh/authorized_keys:

how do you get there or are those dir created?
