+So, inspired from J[erry Ng's Ghost backup script](https://jerrynsh.com/backing-up-ghost-blog-in-5-steps/) 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.
+
+<!--more-->
+
+## 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](https://min.io/docs/minio/linux/reference/minio-mc.html).
+- S3 Compatible storage server (in this case Minio)
+
+## Script
+
+```bash
+#!/bin/bash
+# Backup ghost website(s) to Minio
+# Inspired from https://jerrynsh.com/backing-up-ghost-blog-in-5-steps/
+# 
+# This script also need Minio CLI configured, see:
+# https://min.io/docs/minio/linux/reference/minio-mc.html
+# Or edit and adapt with your favorite s3 client on
+# S3_SECTION below.
+
+set -e
+
+MINIO_REMOTE_ALIAS="myminio" # your mc `alias` name
+MINIO_BUCKET="backups"
+MINIO_FOLDER="ghost/"        # Mandatory, don't forget the trailing slash at the end
+
+# Array of website, `IFS` property separate by `|`
+# `IFS[0]` = website shortname, used to organize backuo folder location on S3
+# `IFS[1]` = Ghost website directory
+GHOST_WEBSITES=(
+    "example_blog1|/path/to/blog1"  # 1st website
+    "example_blog2|/path/to/blog2"  # 2nd website
+)
+
+##### End basic config #####
+
+SCRIPT_DIR=$( cd -- "$( dirname -- "${BASH_SOURCE[0]}" )" &> /dev/null && pwd )
+
+for WEBSITE in "${GHOST_WEBSITES[@]}"
+do
+    IFS='|' read -ra WEBPARAMS <<< "$WEBSITE"
+    if [ ! -d "${WEBPARAMS[1]}" ]; then
+        echo "Folder not exists.. Skipping ${WEBPARAMS[0]}"
+    else
+        BACKUPDATE=`date +%Y-%m-%d-%H-%M`
+        echo "Performing backup ${WEBPARAMS[0]}"
+        cd ${WEBPARAMS[1]}
+        
+        ### ARCHIVE ###
+        tar -czf $SCRIPT_DIR/$BACKUPDATE-${WEBPARAMS[0]}.tar.gz content/ config.production.json package-lock.json
+        
+        ### DATABASE SECTION ###
+        db_user=$(ghost config get database.connection.user | tail -n1)
+        db_pass=$(ghost config get database.connection.password | tail -n1)
+        db_name=$(ghost config get database.connection.database | tail -n1)
+        mysqldump -u"$db_user" -p"$db_pass" "$db_name" --no-tablespaces | gzip > "$SCRIPT_DIR/$BACKUPDATE-$db_name.sql.gz"
+        
+        ### S3_SECTION ###
+        # adapt to your env
+        mc cp $SCRIPT_DIR/$BACKUPDATE-${WEBPARAMS[0]}.tar.gz $MINIO_REMOTE_ALIAS/$MINIO_BUCKET/$MINIO_FOLDER${WEBPARAMS[0]}/$(date +%Y)/$(date +%m)/$BACKUPDATE-${WEBPARAMS[0]}.tar.gz
+        mc cp $SCRIPT_DIR/$BACKUPDATE-$db_name.sql.gz $MINIO_REMOTE_ALIAS/$MINIO_BUCKET/$MINIO_FOLDER${WEBPARAMS[0]}/$(date +%Y)/$(date +%m)/$BACKUPDATE-$db_name.sql.gz
+        
+        
+        # REMOVE LOCAL BACKUP
+        rm -f $SCRIPT_DIR/$BACKUPDATE-${WEBPARAMS[0]}.tar.gz
+        rm -f $SCRIPT_DIR/$BACKUPDATE-$db_name.sql.gz
+	cd $SCRIPT_DIR
+    fi
+
+done
+
+exit 0

+
+## 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.
