Small WordPress backup script

Simple backup script written in bash, for WordPress on Linux, that will dump MySQL database used by WordPress site and create tar.gz file consisting of WordPress site files and database dump

#!/bin/bash

BKPDIR=/local/backup/directory
WEBROOT=/wordpress/install/directory/

DBUSER=$(grep DB_USER $WEBROOT/wp-config.php | awk -F\' '{print$4}')
DBNAME=$(grep DB_NAME $WEBROOT/wp-config.php | awk -F\' '{print$4}')
DBPASSWORD=$(grep DB_PASSWORD $WEBROOT/wp-config.php | awk -F\' '{print$4}')
DBDUMP="$BKPDIR""$DBNAME"_$(date +"%Y-%m-%d-%H-%M").sql

#In case you want to rsync backups to remote server
RUSER=remoteuser
RHOST=remoteserver
RDIR=/remote/backup/directory/
RSSHPORT=22

mysqldump -u $DBUSER -p$DBPASSWORD $DBNAME > $DBDUMP

tar -czvf "$BKPDIR"wpbackup_$(date +"%Y-%m-%d_%H-%M").tar.gz $WEBROOT $DBDUMP

rsync -az $BKPDIR -e "ssh -p $RSSHPORT" $RUSER@$RHOST:$RDIR

It will create two backup files, one for database dump in format that looks like “dbname_2018-01-04-06-00.sql” and one tar.gz file that will look like “wpbackup_2018-01-04_06-00.tar.gz”.

Script can be saved as wpbackup.sh and put in crontab to run at a certain time like 6:00AM.
