Proxmox-Backup Restore
Proxmox Backup and Restore
This guide provides options for consistently backing up a server, instructions for restoring from backups, and best practices for testing backups prior to needing them.

Assumptions
This guide focuses on Proxmox servers and assumes:
- A directory is established on the server for backups. Example: `/datadrive/Backups/`
- Services run within containers and VMs on the Proxmox server (host).
- SSH keys have been established and copied into each VM and container. Refer to the SSH Keys guide for more on SSH key generation and usage.
For specific service guides, see:

Restore
Instructions for restoring from backup will depend on the specific service and the type of backup used. Refer to the Authentik Backup or other service-specific guides for restoration steps.
