I have a trusty UnRaid server that has been running great for almost 3 years now, with some kinks and headaches here and there, but mostly very stable. Now I'm entertaining the idea of setting that box up with ProxMox, and running UnRaid virtualized. The reason being that I want to use UnRaid exclusively as a NAS and then run all dockers and VMs on ProxMox (at least that's how I'm picturing it). I would like to know your opinion on this idea. All I have is Nextcloud, Immich, Vaultwarden, Jellyfin, Calibre, Kavita and a Windows VM I use to update some hardware every now and then. I mainly want to do that for the backup capabilities in ProxMox for each instance. Storage is not a concern, and I have 64GB of ECC Ram running in that box. What are the Pros and Cons, or is it even worth it to move all this to ProxMox?
If you want to move to Proxmox then I say give it a go.
Maybe just keep what you have running and set up another machine to have a play. If you like it, then stick it on your main machine and work out how to replace everything, could be a fun project for you.
I use Proxmox and have Open Media Vault as my NAS. I use SMB/CIFS to share the drives and have a share that Proxmox can use for daily backups, as well as having backups on the main SSD every week. I need to off-site backups but I haven't researched that yet.
I have a Debian VM that runs Docker and have everything running on that except OMV and Home Assistant. I have another Debian VM that I spin up to try things out.
RAM-wise I'm hitting about 12gb so if you have something with 16 lying around you can easily try out most of what you have running already, and if you don't have anything to run it on you're talking under £100 for a mini PC.
Give it a go, I'm sure you can come up with something to run on a mini pc anyway
This is actually good advise. I am running ProxMox on a very old PC (3rd Gen i3 with 8GB of ram), and I really like it, which is why I wanted to move it to my server Box instead.
But now that you mention it, I may be better off keeping my UnRaid box as it is and use is as NAS/Storage exclusively and then build a good box to run everything else from ProxMox.
My wife is going to kill me in my sleep, lol.
