Proxmox Docker Volume Backup and Restore Script

This script performs backup and restore operations for Docker volumes within Proxmox LXC containers.

Requirements

• Ensure that sshpass is installed. For installation instructions, visit: Cyberciti: SSH Password Provider.
• Root login with a password must be enabled on the Proxmox host. Follow these steps:
  1. Edit the /etc/ssh/sshd_config file and apply the following configuration settings:
     • ListenAddress 0.0.0.0
     • PasswordAuthentication yes
     • PermitRootLogin yes
  2. Restart the SSH service using the command:

     systemctl restart sshd
     

Usage

To use the script for backup and restore operations, execute the following commands:

• To backup a volume:

  ./proxmox.sh backup --host <host> --user <user> --lxc <lxc_number> --volume <volume> --path <path>
  

• To restore a volume:

  ./proxmox.sh restore --host <host> --user <user> --lxc <lxc_number> --volume <volume> --path <path>
  

Parameters

• host: Proxmox host IP address or hostname
• user: Proxmox host username
• lxc: LXC container number
• volume: Name of the Docker volume
• path: Path for the backup location

Examples

• To backup a volume:

  ./proxmox.sh backup --host 192.168.0.100 --user root --lxc 100 --volume searxng_data --path /Users/hhf/backup
  

  The backup file will be saved to /Users/hhf/backup/hhf_data-backup.tar.gz.

• To restore a volume:

  ./proxmox.sh restore --host 192.168.0.100 --user root --lxc 100 --volume searxng_data --path /Users/hhf/backup
  

  The backup file will be restored from /Users/hhf/backup/searxng_data-backup.tar.gz, so please ensure that the file exists. This action will overwrite existing files within the Docker volume.
