Create a Logical “Dump” SQL File

The procedure to create a backup depends on the operating system.

If you plan to restore the backup to a MariaDB Cloud service, the mysql database should be excluded from the backup by specifying --ignore-database=mysql, because MariaDB Cloud user accounts do not have sufficient privileges to restore that database.

Linux

1. Determine the connection parameters for your MariaDB Cloud service.

2. Use your connection parameters in the following command line:

mariadb-dump --host FULLY_QUALIFIED_DOMAIN_NAME --port TCP_PORT \
      --user DATABASE_USER --password \
      --ssl-verify-server-cert \
      --all-databases \
      --ignore-database=mysql \
      --single-transaction \
      --events \
      --routines \
      --default-character-set=utf8mb4 \
      > skysql_dump.sql

• Replace FULLY_QUALIFIED_DOMAIN_NAME with the Fully Qualified Domain Name of your service.

• Replace TCP_PORT with the read-write or read-only port of your service.

• Replace DATABASE_USER with the default username for your service, or the username you created.

After the command is executed, you will be prompted for a password. Enter the default password for your default user, the password you set for the default user, or the password for the database user you created.

Windows

1. Fix your executable search path.

   On Windows, MariaDB Dump is not typically found in the executable search path by default. You must find its installation path, and add that path to the executable search path:

   SET "PATH=C:\Program Files\MariaDB 10.6\bin;%PATH%"

2. Determine the connection parameters for your MariaDB Cloud service.

3. Use your connection parameters in the following command line:

mariadb-dump --host FULLY_QUALIFIED_DOMAIN_NAME --port TCP_PORT \
      --user DATABASE_USER --password \
      --ssl-verify-server-cert \
      --all-databases \
      --ignore-database=mysql \
      --single-transaction \
      --events \
      --routines \
      --default-character-set=utf8mb4 \
      > skysql_dump.sql

• Replace FULLY_QUALIFIED_DOMAIN_NAME with the Fully Qualified Domain Name of your service.

• Replace TCP_PORT with the read-write or read-only port of your service.

• Replace DATABASE_USER with the default username for your service, or the username you created.

After the command is executed, you will be prompted for a password. Enter the default password for your default user, the password you set for the default user, or the password for the database user you created.

MariaDB Dump 10.3 and Older

The instructions provided above are written for MariaDB Dump 10.4 and later, which uses the binary filename of mariadb-dump.

For MariaDB Dump 10.3 and older, the binary filename was mysqldump. The instructions can be adapted for MariaDB Dump 10.3 and older by executing mysqldump rather than mariadb-dump.

Temporal Tables

For system-versioned tables and transaction-precise tables, MariaDB Dump only backs up current row versions. It does not back up historical row versions.
