mysqldump is a tool that allows you to perform logical backups for your MySQL databases. The output of mysqldump is a SQL file that can be used later to restore one or more databases.
Gzip can be used togheter with mysqldump in order to compress the size of the output. It has 9 leveles of compression, 6 being the default one.
Let's assume we have a database named
for which we want to create a dump and compress it using gzip (default level of compression). We can achieve it with the following command:
mysqldump my_app | gzip > my_app_backup.sql.gz
Let's assume we want to backup the same
database, but this time with a compression level of 8. We can do it with the following command:
mysqldump my_app | gzip -8 > my_app_backup.sql.gz
