mariabak: Making MariaDB and MySQL backups a breeze

About

mariabak is a opensource command-line program frontend for mysqldump to make MariaDB and MySQL databases backups. Some operations are easier using mariabak than using mysqldump directly.

Project page

https://github.com/llagerlof/mariabak

Let's see some of the goodies:

  • You can opt-out dump data from specific tables. The good news: the tables structure will be preserved (mysqldump doesn't have this as a native option so you need to execute more than one command to do this).

  • You can perform backup of all databases at once, or just some chosen databases, creating one dump file for each database (mysqldump put all databases into one single dump file).

  • One directory with a timestamp will be created for each mariabak execution (more than one file is generated for each backup, so let's keep things organized).

  • It backups all the user grants, system variables and events to separate files.

Hands-on

Demonstration

Usage examples

List databases:

$ mariabak -list     # default localhost, user root, empty password
Enter fullscreen mode Exit fullscreen mode

Backup all databases. A directory will be created in current directory:

$ mariabak --databases=*
Enter fullscreen mode Exit fullscreen mode

Backup one database, asking for the server password interactively:

$ mariabak --databases=db1 --host=localhost --user=root -p
Enter fullscreen mode Exit fullscreen mode

Backup some databases, ignore some tables data but preserve its structure:

$ mariabak --databases=db1,db2,db3 --ignore-tables=db2.table1,db2.table2,db3.table_a --user=root -p
Enter fullscreen mode Exit fullscreen mode

Backup one database, passing the server password inline:

$ mariabak --databases=db1 --host=localhost --user=root --port=3306 --password=hunter2  # Caution with this one. The shell can save command history.
Enter fullscreen mode Exit fullscreen mode
