External SSD/HDD
A removable backup disk used as off-host storage
Core Idea
External SSD/HDD means a removable disk that you plug into the Proxmox host, mount as Directory storage, use for backups, and then unplug again. That physical separation is what turns a normal backup copy into something closer to an offline or off-site recovery asset.
Why It Matters Here
Mathbong uses this term in Proxmox backup and recovery posts when comparing simple off-host backup options against NAS or PBS.
