## Backup

Specify the above environment variables to switch to the MySQL(MariaDB) database.

<br>



## Restore

When restoring, also specify the above environment variables to switch to the MySQL(MariaDB) database.

1. Ensure that the database is accessible.

Perhaps you will use the `docker-compose up -d [services name]` command to start the database separately.

2. Verify that the `MYSQL_HOST` you are using is accessible to.

If your database is running in docker-compose, you need to find the corresponding network name via `docker network ls`  and add `--network=[name]` to the restore command to specify the network name.

3. Restore and restart the container.
