How can create an automatic backup for it?

Answer 1

Guessing that you are using an unix-like OS. You need to do two steps

Backup your current database

First you need to know how to use mysqldump. This should be a good start point.

mysqldump --all-databases --single-transaction --quick --lock-tables=false > full-backup-$(date +%F).sql -u root -p

Cron your mysqldump

You need to create a file with your credentials. Something like this

sudo nano /home/example_user/.mylogin.cnf

[client]
user = root
password = MySQL root user's password

chmod 600 /home/example_user/.mylogin.cnf

Then, you have to add this line to your cron

sudo nano crontab -e
0 1 * * * /usr/bin/mysqldump --defaults-extra-file=/home/example_user/.my.cnf -u root --single-transaction --quick --lock-tables=false --all-databases > full-backup-$(date +\%F).sql

And that's all.
