+# Author: Husni Adil Makmur
+# GitHub: https://github.com/husniadil
+
+# This script performs backup and restore operations for Docker volumes within Proxmox LXC containers.
+
+# Requirements:
+# - Ensure that `sshpass` is installed. For installation instructions, visit: https://www.cyberciti.biz/faq/noninteractive-shell-script-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 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
+
+# Example:
+# - To backup: `./proxmox.sh backup --host 192.168.0.100 --user root --lxc 100 --volume searxng_data --path /Users/husni/backup`
+#     > The backup file will be saved to `/Users/husni/backup/searxng_data-backup.tar.gz`.
+# - To restore: `./proxmox.sh restore --host 192.168.0.100 --user root --lxc 100 --volume searxng_data --path /Users/husni/backup`
+#     > The backup file will be restored from `/Users/husni/backup/searxng_data-backup.tar.gz`, so please ensure that the file exists. This action will overwrite existing files within the Docker volume.
