Hi everyone, this is my first time using Proxmox. I need some help with this one. I have two VMs, Windows 10 Pro and Ubuntu 22.04. I want to mount a drive to Ubuntu and allow Ubuntu full control. I want that same drive mounted in Windows as read only and maybe Backblaze can backup the contents. Is this possible? Thanks for your help!
 
Backblaze will identify the disk as virtual disk and won't back it up. Tried that a year ago. Sadly all backup providers with unlimited storage know that people running linux/unix got way to many files so they only support Windows and MacOS.

Of course it will. Thanks for the help. I can still use proxmox for my web services, Plex, and my DVR. looks like I need to look into alternatives to backblaze or build a NAS.

But then a Windows based NAS as Backblaze won't allow to backup SMB/NFS shares and won't run on linux/unix so all the NAS OSs like TrueNAS, OpenMediaVault, Xpenology, Unraid, ... won't work.

And for the shared disk...block storages aren`t made to be used by two OSs at a time. There might be some tricks to do it if one of them is read only, but I think thats still very dangerous as you easily could corrupt your data. Best you setup a NAS VM/LXC and use SMB/NFS shares as shared folders.

Yeah, I'm thinking it will be a Windows NAS.
