Creating backups to increase your site’s redundancy is a smart move in the face of a disaster. This is why most website admins build and download an offline version of their website data every single day for recovery. However, this traditional method of doing things has two major drawbacks. For one, it’s effort-intensive (i.e., not lazy-proof), and two, you lose all your recent data if your website crashes before you have a chance to create your daily backup!

In this article, we’ll look at how to back up your website’s backend MySQL database in Linux or Ubuntu. But for those of you who are looking for a more elegant solution, we will also cover automated backups. With automation, once you set it up, you don’t need to worry about that one time you forgot to create a backup or pushing all changes made to your website onto the recovery copy. It takes care of it for you!

Backup MySQL Database on Linux/Ubuntu

MySQL provides a command-line utility, mysqldump, that can be utilized to create backups by exporting databases as raw SQL files. You can run the command manually every day or install an automation script, like automysql backup, that will do it for you on a daily basis.

  • Use the mysqldump Command:

From your terminal, without logging into your MySQL console, execute the command using the basic syntax:

$ mysqldump -u [username] -p[password] [database_name] > [backup_file_name].sql

Note that there is no space between -p and the password you input.

  • Back-Up a Single Table

You can also back up the data of an individual table directly onto a text file using the general syntax mentioned below:

Select * Into Outfile 'table_backup_file' From name_of_table;

  • Restore MySQL Database:

To restore your database from the backup you created in the previous step, log in to MySQL console by entering your credentials:

$ mysql -u [username] -p

Once you’re logged in, type the following command to restore the database, modifying the parameters as required:

$ mysql -u [username] -p[password] [database_name] < [backup_name].sql

  • Automate the Backup Process:

To automatically back up your database, you will first need to install the automysqlbackup package. To do this, use the following command:

$ sudo apt-get install automysqlbackup

The script will run automatically on a daily basis, and backups will be stored under the “/var/lib/automysqlbackup” directory. Additionally, you can create a crontab entry to run automysqlbackup at any particular time.

To view the contents of the daily backup folder, run the following command:

$ sudo ls -a /var/lib/automysqlbackup/daily

If you’d like to modify any configurations or add customizations to the utility, you can edit the file located at “/etc/default/automysqlbackup” by executing the command below:

$ sudo nano /etc/default/automysqlbackup

To create on-demand backups, run the command manually, as shown below:

$ sudo automysqlbackup

Step 2: Obtain the Required Information to Add Your Website

For adding a website via FTP or SFTP, you will need some information from your hosting provider such as:

  • the URL of the website you want to add,
  • the FTP or SFTP server,
  • user credentials, and
  • port number.

You can find this information under settings in your hosting account. It’s always recommended to use SFTP instead of FTP whenever possible, as it’s more secure.

Add your website

Step 3: Select Your Root Directory

If the connection is successful, the next step takes you to the Capture Your Code window, where you must select or manually specify your root directory. Next, press Select Root Directory.

Step 5: Add a Database from the Completion Window

Once your first backup is complete, you will be taken to the completion window. From here, you can add a database to back it up, or you can also do it from your website dashboard.

Note: You cannot add a database without adding a website first.

To add a database, you will need:
