    Shell Script To Take Backup of the Database

    First create a script under the home directory of the account lets say

    /var/www/vhosts/yourdomain.com/mysqldatabasebackupscript.sh

    In this case I am taking the example of domain hosted on the Linux Plesk Server, please change the paths accordingly for cPanel servers

    Then chmod 755 /var/www/vhosts/yourdomain.com/mysqldatabasebackupscript.sh

    Now configure a cron

    vi /var/spool/cron/username

    Add the following command
    —————————————
    0 22 * * * sh /var/www/vhosts/yourdomain.com/mysqldatabasebackupscript.sh
    —————————————

    Now add the following script at /var/www/vhosts/yourdomain.com/mysqldatabasebackupscript.sh
    ===========================

    #!/bin/sh
    now=”$(date +’%d_%m_%Y_%H_%M_%S’)”
    filename=”dbname_backup_$now”.sql.gz
    backupfolder=”/var/www/vhosts/yourdomain.com/httpdocs/dbbackups”
    fullpathbackupfile=”$backupfolder/$filename”
    logfile=”$backupfolder/”backup_log_”$(date +’%Y_%m’)”.txt
    echo “mysqldump started at $(date +’%d-%m-%Y %H:%M:%S’)” >> “$logfile”
    mysqldump –user=mysqlusername –password=userpassword –opt dbname | gzip > “$fullpathbackupfile”
    echo “mysqldump finished at $(date +’%d-%m-%Y %H:%M:%S’)” >> “$logfile”
    chown username.psacln “$fullpathbackupfile”
    chown username.psacln “$logfile”
    echo “file permission changed” >> “$logfile”
    find “$backupfolder” -name db_backup_* -mtime +8 -exec rm {} \;
    echo “old files deleted” >> “$logfile”
    echo “operation finished at $(date +’%d-%m-%Y %H:%M:%S’)” >> “$logfile”
    echo “*****************” >> “$logfile”
    exit 0
    ===========================

    Note:- backupfolder path in in the root of the domain please set it according to the actual root of the domain

    As the script was desined for plesk server I’ve set the ownership to username.psacln, please change it to username.username for cPanel server

    In the above command now is reading the current time

    backupfolder is reading the path of the folder where you wish the backup files to get stored

    Define the database username like I did –user=mysqlusername –password=userpassword and name of the database to backed up in this case it is dbname .
