Automatically Backup MySQL database on linux server

Question

I need a script that automatically makes a backup of a MySql Database. I know there are a lot of posts and scripts out there on this topic already but here is where mine differs

Answer 1

Create a shell script like the one below:

#!/bin/bash
mysqldump -u username -p'password' dbname > /my_dir/db_$(date+%m-%d-%Y_%H-%M-%S).sql
find /mydir -mtime +10 -type f -delete

Replace username, password and your backup directory(my_dir). Save it in a directory(shell_dir) as filename.sh

Schedule it to run everyday using crontab -e like:

30 8 * * * /shell_dir/filename.sh

This will run everyday at 8:30 AM and backup the database. It also deletes the backup which is older than 10 days. If you don't wanna do that just delete the last line from the script.
