Up till now I’ve been running Debian on a 2008 Dell tower as my homeserver. I just got 2 1tb drives for it so I want to upgrade to an actual dedicated NAS software to simplify how I manage it. The problem is, I only have 4gb of RAM in it. Any recommendations?
Edit: For context, I mostly use the server for Nextcloud and Syncthing but I also want to be able to have a generic Debian server with ssh access available if I need it.
I haven’t used it, but maybe look at Cockpit? You could install it on your generic Debian server and it would give you a nice gui and tools, while letting you do whatever you are currently using it for.
I am using openmediavault for my NAS, which seems reasonably lightweight and is debian based. If that fits the bill
First of all, 4 GB is not so bad, I ran with 4 GB on mine for years. In fact I’m still not using more than 4 GB even though I have more RAM now, it still takes 3.7 GB right now and I run 20 containers.
I don’t run Nextcloud though, and I don’t run VM’s. VM’s definitely would need more RAM, and I don’t know how much Nextcloud wants. Syncthing wants very little.
Think about why do you want a GUI, they don’t typically offer that much if you already know your way around Linux. And once you set up a container it will keep working indefinitely (until you upgrade it anyway, but that’s another kettle of fish).
You also don’t need anything fancy to put together a RAID1 out of those two disks, if that’s what you mean to do.

Why not just run TrueNAS Scale? It’s a NAS built on top of Debian?
Minimum RAM for TrueNAS is 8gb. I really should get more RAM though.
You technically can run on 4, but you won’t have much in the way of ZFS cache and forget about containers like nextcloud/syncthing. You’ll get NFS/SMB and rsync and that’s it.
My syncthing container consumes about 100 MB of RAM.
So you want to put one of those web management front ends on your existing server?
Well… Do you want it to be a dedicated NAS, or do you want a generic Debian server? Because those are pretty much mutually exclusive.
You probably want to just stick with Debian for running whatever, and then just present storage over smb, nfs, or whatever.
OpenMediaVault! It has a nice web UI and it’s Debian based. However the development cycle doesn’t always line up with Debian releases so sometimes it can take a few months to switch major versions.
Pretty much any?
Headless distros won’t really differ in RAM usage. The only generic OS property that I could relistically see saving significant resources in this regard would be 32bit but that’s… eh.
What’s more important is how you utilize the limited resources. If you have to resort to containers for everything and run 50 instences of postgres, redis etc. because the distro doesn’t ship the software you want to run natively, that won’t work.
For NAS purposes and a few web services though, even containers would likely work just fine.
