Ghost multi-blog backup bash script to Minio (S3 Compatible)

Simple bash script to automatic backup multiple Ghost blog on the same server to remote AWS S3 compatible server.
On this page

So, inspired from Jerry Ng’s Ghost backup script which can be used to backup single blog site to remote storage using rclone, I write this script that can be used to automatic backup multi Ghost blog on the same server to remote AWS S3 compatible server (in this case Minio) using Minio-CLI.

What’s backed up?

  • config.production.json and package-lock.json file.
  • Everything under content/ directory.
  • MySQL dump database.

Structure of generated backup on remote backup location (S3): [BUCKET_NAME]/ghost/[WEBSITE_NAME]/[YEAR]/[MONTH]/.

Requirements

  • Access to Linux Ghost admin user.
  • Configured Minio CLI.
  • S3 Compatible storage server (in this case Minio)

Script

 1#!/bin/bash
 2# Backup ghost website(s) to Minio
 3# Inspired from https://jerrynsh.com/backing-up-ghost-blog-in-5-steps/
 4# 
 5# This script also need Minio CLI configured, see:
 6# https://min.io/docs/minio/linux/reference/minio-mc.html
 7# Or edit and adapt with your favorite s3 client on
 8# S3_SECTION below.

12MINIO_REMOTE_ALIAS="myminio" # your mc `alias` name
13MINIO_BUCKET="backups"
14MINIO_FOLDER="ghost/"        # Mandatory, don't forget the trailing slash at the end
15
16# Array of website, `IFS` property separate by `|`
17# `IFS[0]` = website shortname, used to organize backuo folder location on S3
18# `IFS[1]` = Ghost website directory
19GHOST_WEBSITES=(
20    "example_blog1|/path/to/blog1"  # 1st website
21    "example_blog2|/path/to/blog2"  # 2nd website

How to use

Edit MINIO_REMOTE_ALIAS, MINIO_BUCKET, MINIO_FOLDER and array of website(s) to GHOST_WEBSITES variable. Then you can execute the script using cron.
