name: MSSQL backup via SqlPackage
about: Use SqlPackage Extract and Publish actions to backup and restore the MSSQL database.

Description of the feature
Instead of sharing a volume between containers (which is not always possible), we should use SqlPackage Extract and Publish actions to backup and restore the MSSQL database.

Benefits of feature
As mentioned above, using SqlPackage eliminates the need to share a volume between the database and the backup container, resulting in a much cleaner solution. It also handles scenarios where the MSSQL database is hosted on a server outside the cluster and direct connections are not possible.
