Where Does Proxmox Backup Server Store Data?
Proxmox Backup Server config and datastore mount paths on Debian backup appliances. With backup tips.
Last updated
Proxmox Backup Server splits config and chunks cleanly. Settings live in /etc/proxmox-backup with users, datastores, and remotes. Backup data lives in datastore paths, commonly under /mnt/datastore.
Chunks dedup across Proxmox VE clients inside each store. The web UI manages both trees. Back up the config folder with datastore contents. Datastores without the config lose user and schedule context. Prune jobs expire old snapshots. Sync pulls remote stores. Namespaces organize clients. Verify jobs check chunk health.
