# 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.
