# Script Name : backup_containers.sh
# Description : Backs up docker containers on a UGREEN NAS with autocompose
# Author      : T. Nguyen / Mavvy (ugreen@mavvy.net)
# Last Update : 2025-05-30
#
# This script is free and released into the public domain, it is provided as
# is without warranty of any kind. You may use, copy, modify, and distribute
# it for any purpose, commercial or non-commercial.
#
# How To Use
# ----------
#
# Put this script on your UGREEN NAS and run it as a privileged user who has
# access to your Docker data folder and the backup locations.
#
# data_dir    This is the folder where your containers place their
#             persistent data, usually /volume1/docker or /volume2/docker
#
# backup_dir  This is where your backup files will be stored.
#             Docker compose files will be exported to *.yml files.
#             Persistant data will be archived into .tar.gz files.
#
#             You can set your preferred subfolder names, default is yml/data
#
# container_stop_list    Some containers need to be stopped first to create a
#                        clean backup file, e.g. databases that are currently
#                        being accessed. The script will stop the container
#                        and start it once the backup is done.
#
# container_ignore_list  This is a list of containers you don't want to backup
#                        because they don't change often, have already been
#                        backed up or use their own backup routines.
#
# data_ignore_list       Same as above but for persistent data folders.
#
# date_suffix            The date and time will be appended to the backups.
#
# -----------------------------------------------------------------------------
