1. Connect to the LXC instance running MariaDB (in this example, api.facundoitest.space) and create a backup using mysqldump. Replace facundo with your username and VeeamReports with your database name:

mysqldump -u facundo -p VeeamReports > veeamreports.bak

1. This command creates a backup file named veeamreports.bak in the current directory.

1. From your local machine or the LXC instance, use scp to transfer the backup file to the Docker host (e.g., racknerd-vpn.facundoitest.space):

scp ./veeamreports.bak [email protected]:/home/facundo/sql-migration/

1. This will place the file in /home/facundo/sql-migration/ on the Docker host.

1. First, enter the Docker container to confirm the backup file’s location:

docker exec -it mariadb /bin/bash

1. Alternative Methods:
   1. Copy the File Directly into the Container:

docker cp /home/facundo/sql-migration/veeamreports.bak mariadb:/veeamreports.bak

1. Mount the Directory During Container Startup (to persist the folder as /backup in the container):

docker run -d --name mariadb -v /home/facundo/sql-migration:/backup mariadb

1. With the backup file accessible in the container, import it into the MariaDB instance by connecting to the container:

docker exec -it mariadb /bin/bash

1. Run the following command to import the database. VeeamReports is the database name and facundo the user:

mariadb -u facundo -p VeeamReports < veeamreports.bak

1. Confirm that the database imported successfully by connecting to MariaDB and checking for tables in VeeamReports:

mariadb -u facundo -p
SHOW TABLES IN VeeamReports;

Notes

1. Permissions: Ensure facundo has the necessary permissions on both the source and destination databases.
2. Container Access: If mariadb is not recognized, try mysql or confirm the correct executable name for MariaDB in your setup.
