WordPress Backup to FTP

Guy — Tue, 06 Jan 2009 13:46:33 +0000

Update: A newer version of the script is available.

This script allows you to easily backup your WordPress blog to an FTP server. It’s actually a modification of my WordPress Backup to Amazon S3 Script, but instead of saving the backup to Amazon S3 it uploads it to an FTP server. Another update is that now the SQL dump includes the database creation instructions so you don’t need to create it manually before restoring from the backup.

Although I’ve written it with WordPress in mind (to creates backups of my blog), it isn’t WordPress specific. It can be used to backup any website that consists of a MySQL database and files. I’ve successfully used it to backup MediaWiki installation.

DUMP_NAME=${DB_NAME}-$(date +%Y%m%d).sql.bz2
mysqldump --user=${DB_USER} --password=${DB_PASS} --host=${DB_HOST} \
 --databases ${DB_NAME} \
 | bzip2 -c > ${BACKUP_DIR}/${DUMP_NAME}
if [ "$?" -ne "0" ]; then
	echo "failed!"
	exit 1
fi
echo "done"
 
echo -n "Creating tarball... "
TAR_NAME=${BLOG_DIR##*/}-$(date +%Y%m%d).tar.bz2
tar -cjf ${BACKUP_DIR}/${BLOG_DIR##*/}-$(date +%Y%m%d).tar.bz2 ${BLOG_DIR}
if [ "$?" -ne "0" ]; then
	echo "failed!"
	exit 2
fi
echo "done"
 
echo -n "Uploading SQL dump and tarball to FTP... "
lftp -u ${FTP_USER},${FTP_PASS} ${FTP_HOST} <
if [ "$?" -ne "0" ]; then
	echo "failed!"
	exit 3
fi
echo "done"

The configuration is done using the variables in the beginning of the script (until the “end of configuration” line). They are pretty self explanatory, and you should adjust them for your site before using the script. If there are variables you don’t understand what they do, see the post about the previous script, and don’t hesitate to comment.
