Would you mind talking a bit about the small decisions you took for a Proxmox setup? I am slowly learning and planning my (very)small server setup. Things like: * Are the VM image backups you mentioned, done to your pool by means of the ZFS snapshots? Or done at the file-level with rsync or similar. * Do you make backups of the Proxmox installation? Similar as before: is Proxmox itself on a ZFS volume, so backups can be done just by doing ZFS snapshots? The installer lets me choose between an LVM-Thin + ext4, or a ZFS filesystem, and I was wondering whether to choose one or the other, for maximum convenience. * "Proxmox is installed on an SSD": isn't that a bit wasteful? I mean, doesn't the Proxmox system just take like 1 or 2 GB at most? I have a Lenovo ThinkCentre m910q which brings a 160GB M.2 NVMe disk, and another 320GB SSD disk... so I an in the process of deciding where to put each thing. Although for bigger storage I'm also considering if adding a 1 or 2 TB USB3 external disk would make sense (to store user backups like photos, documents, and also for the server's system backups)

1. In my case, VM image SSDs are formatted using LVM-Thin. Based on this, Proxmox automatically takes care of snapshotting the VM images for backups. It would work the same if you used ZFS for image storage. 2. No, I do not currently backup the Proxmox config. There is a good script here: https://github.com/DerDanilo/proxmox-stuff https://github.com/DerDanilo/proxmox-stuff 3. If you install Proxmox on a "thin" filesystem (ZFS or LVM-Thin), then yes, you will get snapshot functionality for free. Note that you would have to configure this yourself - Proxmox does not expose a backup feature for its own config. 4. I have two NVMe SSDs. The first is 500GB and is split into two partitions: 100GB for the Proxmox install (LVM + ext4), and 400GB for VM images and containers (LVM-Thin). The second is 900GB and is fully used for VM images. Both are using LVM.

  Seeing how others have organized their systems helps me with doing my own thing. Thanks a lot for sharing!
