As most of you know I work as an Escalation Engineer at Combell.com. Recently I crafted a tiny backup script that makes backups of my own site. While this script is optimized for use on shared servers at Combell.com, it can easily be adapted to be used anywhere.
#!/bin/bash
#### Settings ####
NOW=$(date +"%Y-%m-%d-%H%M")
FULL_PATH=$(pwd)
BACKUP_FOLDER=$FULL_PATH/data/
#### Site-specific Info ####
SITE_PATH="www" #Could also be subsites/subsitename
DB_NAME=`cat $SITE_PATH/wp-config.php | grep DB_NAME | cut -d \' -f 4`
DB_USER=`cat $SITE_PATH/wp-config.php | grep DB_USER | cut -d \' -f 4`
DB_PASS=`cat $SITE_PATH/wp-config.php | grep DB_PASSWORD | cut -d \' -f 4`
DB_HOST=`cat $SITE_PATH/wp-config.php | grep DB_HOST | cut -d \' -f 4`
#### Files backup ####
function files_backup {
zip -r $SITE_PATH.$NOW.zip $SITE_PATH
mv $SITE_PATH.$NOW.zip $BACKUP_FOLDER
}
#### Database Backup ####
function database_backup {
mysqldump -h $DB_HOST -u$DB_USER -p$DB_PASS $DB_NAME > $DB_NAME.$NOW.sql
mv $DB_NAME.$NOW.sql data/$DB_NAME.$NOW.sql
}
#### Runner Class ####
files_backup
database_backup
This script can be run automatically on a Combell-server by adding a cron for this script. You can do this in /etc/crontab by adding for example this:
0 */6 * * * /bin/sh /data/sites/web/youraccountname/backup.sh
The cron above will create a backup every six hours. Do not forget to put this backup.sh script in the root of your account.
Hope this helps you guys.
PS: the FULL_PATH variable is already included since I’m planning to iterate on this script and add more features, even though it’s currently only used to declare the backup directory path.
