Backing up my blog

Recently, my Blog was migrated from a standard Apache document root into docker. My main URL is now https://blog.kushal.net

On my VPS, I have not opted for daily snapshot as backup and I was forced to put a local backup on my server for the files and database.

My Bash script to backup the MYSQL database and files on the docker containers:-
The output will be stored in a targz file

need to replace the variables by correct name

#!/bin/bash
#Script to backup MYSQL DB and DocRoot of Site web for docker

#Variables
BACKUPNAME=<NAMEOFBACKUP>
DBCONTAINERNAME=<DB_NAME_OF_CONTAINER>
DBUSERNAME=root
DBPASSWORD=<Password_of_root_DB>
DBNAME=<DBNAME>
WEBVOLNAME=<VolumeNameOf_WEBDATAfiles>

DATE=`date +%d-%m-%y`

BACKUPPATH=/home/backup/$BACKUPNAME-$DATE
LOG=$BACKUPPATH/backup.log

function backupdb {
	echo "[`date +%H:%M:%S`] Backing Up DB $DBNAME" >> $LOG
	docker exec $DBCONTAINERNAME /usr/bin/mysqldump -u $DBUSERNAME --password=$DBPASSWORD $DBNAME |gzip > $BACKUPPATH/$DBNAME-`date +%H:%M:%S`.sql.gz
	if [ $? -eq 0 ]; then
		echo "[`date +%H:%M:%S`] Backup Success [OK]" >> $LOG
	else
		 echo "[`date +%H:%M:%S`] Backup failed [KO]" >> $LOG
	fi
}

function backupwebvol {
	echo "[`date +%H:%M:%S`] Backing Up WEB Volume $WEBVOLNAME" >> $LOG
	docker run -t --rm -v $WEBVOLNAME:/var/www/html -v $BACKUPPATH:/backup alpine tar -czvf /backup/backupdocroot-`date +%H:%M:%S`.tar.gz  -C /var/www ./
	if [ $? -eq 0 ]; then
             echo "[`date +%H:%M:%S`] Backup Success [OK]" >> $LOG
        else
             echo "[`date +%H:%M:%S`] Backup failed [KO]" >> $LOG
        fi 
}

function main {
	mkdir $BACKUPPATH
}

case "$1" in
  start|"")
	main
        backupdb
	backupwebvol
        ;;
  restart|reload|force-reload)
        echo "Error: argument '$1' not supported" >&2
        exit 3
        ;;
  db)
       backupdb
        ;;

	backupwebvol
	;;
  *)
        echo "Usage: backup_BLOG.sh [start|db|web]" >&2
        exit 3
        ;;
esac

I have a daily cron which executes the script and a retention of 1 Month locally on the server.

The backup is also externalized with a synchronisation from my RaspberryPi at home with a daily rsync

The backup is save as follows:

blogkushal-30-11-18
├── backupdocroot-11:42:03.tar.gz
├── backup.log
└── blogkushal-11:42:01.sql.gz
