How To Backup Single and Multiple MySQL Databases?

How To Backup Single And Multiple MySQL Databases

Hello guys, In this article, We will discuss how to backup single and multiple MySQL databases. We can backup MySQL databases using mysqldump utility. The backup files created by mysqldump consists of SQL statements that can be used to recreate the original databases.

It can also be used to backup and restore the database on a remote server at the same time or transfer the database to another server. You should backup your databases daily or you may lose all the data if a hard-drive failure or bug occurs.

Mysqldump command

The basic syntax of mysqldump command is as follows:

mysqldump [options] > filename

Backup a single MySQL database

To back up a single database, first, create a backup of the database by logging in as root by executing the following command.

mysqldump -u root -p databasename > filename

Enter your MySQL root user password if prompted. Save it to a file named backup.sql.

mysqldump -u root -p abc > backup.sql

If you are already logged in as root, change the above command as shown:

mysqldump databasename > filename

Backup Multiple MySQL Databases

To back up multiple MySQL databases, use –databases to list multiple databases as shown:

mysqldump -u root -p --databases databasename1 databasename2 databasename3 > filename
mysqldump -u root -p abc1 abc2 abc3 > backup.sql

Backup All MySQL Databases

To back up all the MySQL databases, simply replace –databases to –all-databases in the above command, as shown:

mysqldump -u root -p --all-databases > backup.sql

Backup MySQL Database in a Compressed File

Sometimes, the databases may be too large in size, we can also back up the databases to a compressed file using the gzip utility, as shown:

mysqldump databasename | gzip > filename.sql.gz

Restore the Backup File

To restore the backup file, You can do it by running a command as shown:

mysql databasename < filename.sql
mysql abc < backup.sql


So, We learned how to single, multiple, and all databases using a single line command. We also covered backing up the databases to a compressed file and restoring the backup file. Thank you for reading!
