RNDU4000, use as external HDD?
Hello,
I have a RAID10 setup in my home PC, as well as in the basement's server + SAN. These are meant to back up each other on a weekly basis.
The problem is that the basement is about three kilometres away. As I don't feel like dragging the 20kg PC there, I wonder if a dust-collecting ReadyNAS Ultra 4 (RNDU4000) can act as a simple external hard drive? By raiding the RAID, or ghosting? The RNDU4000 runs OS 6, and all four systems have equal setups - 4x2TB in RAID10.
Thanks :smileyhappy:

So it is possible to install VeraCrypt on the NAS? Is there an app or something? Tried several apps from https://apps.readynas.com/pages/?page_id=9, however all threw error messages and failed to install.
Veracrypt itself is installed on the PC and the server, The veracrypt container is on the NAS. Since the encryption is client-side, stealing the NAS wouldn't compromise the data.

1. The PC. All information that should be backed up is offloaded to a RAID on the PC.
2. PC -> NAS. The NAS clones above mentioned RAID off the PC.
3. NAS -> Server. The NAS is physically brought to the basement for the server to clone (reverse version of the PC)
4. Server -> SAN. The SAN unit will then clone the server's backup.
...
I really don't mind the Ultra4 taking its time. The basement is a hobby room full of retro junk to play around with. Besides, this is just a personal life backup, which isn't about to grow exponentially. It's currently 800GB, of which at least 300GB are uncut videos to be thrown away. We talk, perhaps, an increase of ~25MB a week on median, which can't really take that long to synchronize?Incremental backup should only take a few minutes, so the approach should work. You will need to be careful when transporting the NAS - at least checking that all the drives are fully seated before powering it up in the new location. There are some posts here from folks who've run into problems after tranporting their NAS.
Something along these lines would also do the job I think: https://www.bhphotovideo.com/c/product/1113481-REG/apricorn_a25_3pl256_2000_aegis_padlock_usb.html So if you are purchasing new drives for the NAS, you might consider that alrenative.

I don't understand what you mean by "acting as a simple external hard drive". The volume already acts that way.
But you can certainly use the Ultra to backup any of these devices over wired ethernet. You can't connect to to the server's USB port.

Not sure if this is intended literally or not.
If everything is on the same wired network, then there is no need to move anything to make the backups. There are several utilities out there that can do incremental backups over the network. FreeFileSync is one free one (among others). Even a full backup of 4 TB of data can be done in less than a day over gigabit ethernet.
If the home PC (and Ultra) are actually in different locations (on different networks), then it is still possible to back up the basement equipment to them - though it does depend on the internet upload/download speeds of the two networks. You can set up a VPN connection for remote access (for instance using ZeroTier or OpenVPN). If the server is running linux, then you could also set up rsync-over-ssh (forwarding ports in the routers).

Thanks for reply. What I mean is that I'd like to mount it as a Windows local disk, just like a USB stick or external HDD. Then it's easily encryptable via VeraCrypt, ghostable via Norton Ghost/RAID etc.

Well, it's always good to point out that the NAS has to be brought down three stairs, carried about 75 m. to the car, getting the car warmed up, driven to the basement storage, getting unloaded after buying a ticket, carried down and all in reversal order; before getting irrelevant comments that I shouldn't be lazy and just bring the 10x heavier PC there. I'm asking because it's either this, or purchasing an external HDD cabinet I have in mind.
Sadly there's no network at the basement at all, and I don't intend to put one up either (partly because it's only for personal backups, and partly because it's in two different apartment complexes, so I guess it'll be outrageously expensive to install fibre network there). That's why I need the NAS to move the infomation physically. :)

Given you will be setting up the Ultra4 from scratch, you may want to look at upgrading it to OS6 before you get started. As the older protocols the RAIDiator 4.2.x software supports become more and more depreciated and the OS just gets older, that will give the NAS new life with current OS updates. You will want to increase the memory to at least 2GB before you do, as there are reports where that seems to be a necessity for the latest 6.10.x versions. Of course, just used as a backup, the use of outdated protocols isn't quite as critical, but I updated all my legacy NAS that could be updated to OS6 and got rid of the rest.
I store next to nothing data wise on internal hard drives and no longer use USB ones at all. Everything is on a primary NAS, which backs up to a pair of backup NAS (because their volumes are smaller and it takes two to hold it all) with the most critical data also backed up three states away at my brother's house via a ZeroTier VPN. I made the initial backup on the NAS at my brother's locally since the data has to go over the internet, but it's not been back in my hands since. He uses it as a primary NAS and his data backs up to one of my backup ones. I administer it remotely through the VPN. All these units are legacy devices running OS6.

Thank you.
It's already upgraded to 6.10.1 unofficial software.
The PC, NAS, server and SAN are in my case, all permanently offline. All data that should be saved is moved to the PC's RAID, using an encrypted USB stick. This RAID is what I want the NAS to clone, so the NAS is all that's needed for the server + SAN for also cloning the information. This will make 8 copies on 4 devices at 2 locations, which should protect from everything but town-wide disasters.

Thanks for removing my clarifications. That's certainly helpful for answering my question and keeping up Netgear's reputation.
Guess I'll try my luck with an Icy Box IB-3740 or Promise SmartStor DS4600, i.e. an external HDD enclosure (DAS), which is what I was asking for.
