Best practice on discs and folders

[citgot]

I’m new to Proxmox and also new to RAID so I need some advice.
I installed Proxmox on a RAID 5 consisting of 4 2TB HDDs. I’ve read that many use a single SSD for Proxmox and also a single disc for Local storage.

I intend to run some VMs on my server. On some VMs I will run docker containers.

How would you recommend that I structure my storage and folders?

The docker containers will need some persistent folders. Should I store the persistent folders within the vm or outside in Proxmox/debian?

My Nextcloud will need samba/NFS shared folders. Run as a VM or directly on Proxmox?

I guess I lack the understanding of how RAID works and how Proxmox and VMs handle folders in a RAID.

Maybe this is the wrong forum but what would be the best practice for a 4 2TB setup with Proxmox, VMs, Docker and samba shares? Is RAID 5 ok or would you do it some other way?

Both versions should work. If Proxmox VE is installed on a single disk, then you lose some redundancy.

The docker containers will need some persistent folders. Should I store the persistent folders within the vm or outside in Proxmox/debian?

My Nextcloud will need samba/NFS shared folders. Run as a VM or directly on Proxmox?

I would separate hypervisor and data/guests. You can create backups of the whole VMs that run docker (that includes all folders) in the GUI, no CLI interaction necessary. So your persistent folders should be safe. Same for Nextcloud shared folders.

Thank you for your input. Backups of the entire VM makes sense and will keep the data safe I guess.

I’m still stuck in my old habits of placing data folders gathered in one place and easy to get to when reinstalling. Time to find new ways with Proxmox.
