 ### Proxmox LXC Suggested Specs
 
 - **RAM:** 512MB (it will rarely use more than 50MB, but this gives headroom)
-- **Disk:** 4GB (more than sufficient)

 - **Privileged container:** Yes (required for NFS)
 
+> **Note:** The LXC disk is the system disk only — Nextcloud data lives on the NFS mount and does not consume space here. rsync and mc stream data directly between the NFS mount and remote machines without staging anything on the local disk. If you ever need local staging space, mount a separate volume rather than enlarging the system disk.
