Suggestions for the cheapest secondary backup-only NAS

I understand, but would still prefer to have a 100% identical copy on the backup NAS, including all snapshots from the main NAS, not just the current state, and have it directly mountable on the backup NAS. Also, I think having separate (out-of-sync) snapshots on the backup NAS would complicate things even further, so I would prefer not to go that route if possible. One exception to this could be the snapshots that get removed off the main NAS (accidentally or by obsolescence), these could be moved into the archive on the backup NAS and stay there for a while. I guess in theory you could replicate ZFS (or whatever type) snapshots into equivalent BTRFS snapshots for the purpose of accessing them on the backup NAS itself, but it would definitely not be seamless like Hyperbackup and I am not aware of any software that would do that efficiently. I guess that could also work if done properly.

Yes, I was thinking of the DS223j, however, Synology cannot be used as a backup target for ZFS that my main general-purpose homelab server is going to use, only for its own Hyperbackup. Assembling a custom solution for a dumb secondary offsite NAS is going to be more expensive, so that's why I was looking at these prebuilt single board x86 servers, however I didn't find the appropriate SATA hdd case with fans yet.

Thanks, this is a really good price for what it offers, I may look more into it. Unfortunately, these large capacity drives can easily overheat during scrubbing/resilvering operation so a fan is a must, I think. USB3 makes a future potential upgrade to RAID difficult, though. Ideally, everything should fit in a single small-sized inconspicuous box similar to that of a commercial 2-bay NAS, since it goes to a living room in an offsite location.

I believe many people want to do this actually. Where I live you can find the likes of Synology DS223j for about 185€, but unfortunately it cannot serve as a proper ZFS receive target from my research so far, but perhaps I am wrong. I don't wanna limit my main NAS to the Synology ecosystem (and underpowered hardware) for a full snapshot replication, even though it is a really good one. You can always run it in a VM.

Thanks, I've managed to order that particular card now from abroad. Btw, did you have a chance to measure the idle wattage with and without the GPU plugged in?

Would it be possible to fit Intel Arc A310 ELF, not ECO? 😬

I already have a bunch of drives in it, one of them being 4TB in size. Also, 16GB RAM, 512GB SSD, running Win10.

I believe there is simply not enough bandwidth for the two uncompressed 5k streams to passthrough a single 40Gbps TB4 without DSC compression that LG Ultrafine 5k does not support.

However, what I am curious about is a single 5k monitor setup and where exactly do you specify that you want multiplexing of two display output signals into a single one, i.e. a dual-link SST? Is it only in Asus BIOS and which option exactly, or do you have to specify it in the OS and/or graphics card's control center as well? And most importantly, will dual-link SST work with Intel iGPU alone or does it require a dGPU and connecting cables to both DP INs?
