RN214 vs RN314 Questions
Greetings. I have an old (in computer years) ReadyNas Duo and am looking to upgrade to something with greater storage capacity. At present, I am considering the RN214 and RN314. To that end, I ha...

Yes. That also allows you to use the Duo for backup.
Note that once the data is migrated, you can do a factory reset on the duo - changing it to flexraid, and creating two RAID-0 volumes (one for each disk). That gives you 4 TB of backup (though it isn't protected from drive failure). I've done this with my own duo.
Using two volumes in the Duo does require you to manual balance storage (choosing which shares to place on which volume). But a single RAID-0 volume will completely fail if either disk fails. I've found balancing the storage isn't that difficult, and it's a lot more robust.
Thanks all for the quick responses. I think that I've settled on the RN424. On my existing ReadyNAS (Duo), I have only manually backed it up; on the new NAS, I plan to avail myself of its automated backup capabilities. To that end, I have some questions:
1) I don't think that it will be practical to backup the entire NAS to a single connected USB3 drive. Does the NAS backup utility provide the ability to automatically backup only select folders from the NAS?
2) To migrate my data from the old NAS to the new one, is it possible to:
a) remove one of the two 2TB drives from the Dua and plug it into the RN424
b) plug the 2TB drive into the RN424
c) plug one new drive (e.g. WD Red 6TB) into the RN424 and watch it perform an automatic cross-copy?
d) remove the 2TB drive from the RN424 and insert the second WD Red 6TB into the RN424 and watch it again perform a cross-copy, or
e) is it better to just plug the two new WD Red 6TB drives into the RN424, format them, create shares, etc., and then copy the old data from the Duo across the network to the new RN424 drives?
E.
Note, if you planned to use the 2tb drives in the new nas, you will have to start with at least one 2tb drive.
If you start with bigger drives, you cannot add smaller drives afterwards.
I would recommend you simply leave your duo intact, setup your new device however you like, then use rsync to copy your data (do one share at a time) from the duo to the new one.
it is a bit time consuming, but that to me is the safest and most reliable method.
Once all data is up and running on your new device, you can reverse your backup jobs so that they pull from your new device over to the duo (424 primary, duo secondary/backup).
at some point, you will probably run out of space on the duo, you could either backup to a usb drive (probably fastest if connected to the 424), or you could reset the duo and setup 2 separate 2tb volumes. You would have double the space, but no redundancy for your backups.
