and you can add the script to cron job under *nix and schedule under windows:
*nix:
Save the following text in file: db_backup.at
10 * * * * ~/backup/backup_db.sh databasename
and call
crontab db_backup.at
You need to change the period to run the script for your business, e.g. each day, each week etc.
