  3. Root user password.
  4. MySQL community server.

Step 1: Use mysqldump Command for Logical Backups

MySQL has a nice command line utility that creates logical backups called ‘mysqldump’. The tool reproduces your MySQL table structure and data without copying the actual data files and outputs the content to a file.

$ mysqldump [options] db_name [tbl_name ...] > backup_file_name.sql
$ mysqldump -u james -p sample_db_1 table_1 > backup_file_name.sql
$ mysqldump [options] --databases db_name ... > backup_file_name.sql
$ mysqldump -u james -p --databases sample_db_1> backup_file_name.sql
$ mysqldump [options] --all-databases  > backup_file_name.sql
$ mysqldump -u james -p --all-databases > backup_file_name.sql
$ ls -a

Step 2: Restoring MySQL Database

You can restore any MySQL database created using mysqldump command using the syntax below:

$ mysql -u username -p database_name < backup_file_name.sql
$ mysql -u james -p sample_db_1 < backup_file_name.sql

Appending date and time on the backup file name

In the above examples, we just used an arbitrary file name to store our MySQL backups. A more professional and convenient way is to append the date on the file name.

$ mysqldump -u james -p --databases sample_db_1> $(date "+%Y_%m_%d_%H_%M_%S")_sample_db_1.sql
$ ls –a

Step 3: Physical MySQL Backups

Logical MySQL backups using mysqldump only works when a database server is up and running. Also, mysqldump utility can be slow for large databases.

$ nano /etc/mysql/my.cnf
$ nano /etc/mysql/mysql.conf.d/mysqld.cnf
$ nano /etc/my.cnf
$ mkdir /var/mysql_backups
$ systemctl stop mysql$ cp -R /var/lib/mysql/* /var/mysql_backups

Step 4: Restoring the Files

When restoring your data files back to MySQL, it is a good idea to rename the current MySQL directory with a different name. Before you do this, make sure MySQL service is stopped.

$ systemctl stop mysql
$ mv /var/lib/mysql /var/lib/mysql-old
$ mkdir /var/lib/mysql
$ cp -R /var/mysql_backups/* /var/lib/mysql
$ chown -R mysql:mysql /var/lib/mysql
$ systemctl restart mysql

Step 5: Automating the Backup Process

Manual MySQL backups are very convenient when you want to take a quick snapshot of your databases. However, this can be a tedious process on a production environment.

$ apt-get install automysqlbackup
$ automysqlbackup
$ ls -a /var/lib/automysqlbackup/daily
$ nano /etc/default/automysqlbackup


In this guide, we have showed you how to create logical and physical backups from your MySQL server hosted on Alibaba Cloud Elastic Compute Service (ECS). We have also outlined the basic steps for running an automated backup using automysqlbackup utility. Running backups on your MySQL server hosted on Alibaba Cloud is the first step towards securing your data in case a disaster strikes your server.
