Overview of this book

Despite being the cloud version of SQL Server, Azure SQL Database and Azure SQL Managed Instance stands out in various aspects when it comes to management, maintenance, and administration. Updated with the latest Azure features, Professional Azure SQL Managed Database Administration continues to be a comprehensive guide for becoming proficient in data management. The book begins by introducing you to the Azure SQL managed databases (Azure SQL Database and Azure SQL Managed Instance), explaining their architecture, and how they differ from an on-premises SQL server. You will then learn how to perform common tasks, such as migrating, backing up, and restoring a SQL Server database to an Azure database. As you progress, you will study how you can save costs and manage and scale multiple SQL databases using elastic pools. You will also implement a disaster recovery solution using standard and active geo-replication. Finally, you will explore the monitoring and tuning of databases, the key features of databases, and the phenomenon of app modernization. By the end of this book, you will have mastered the key aspects of an Azure SQL database and Azure SQL managed instance, including migration, backup restorations, performance optimization, high availability, and disaster recovery.

Activity: Geo-restoring a database hosted on SQL Managed Instance using the Az PowerShell module

Geo-restoring allows you to recover a database to a different region. This can be used as a database recovery solution, but the recovery time depends on the database size. Geo-backups are only available when SQL Managed Instance is configured with geo-redundant backup storage.

Let's quickly go through how to perform a geo-restore using PowerShell.

This activity is similar to the previous point-in-time restore we did using the Az PowerShell module, so all the steps are not covered here. We are only covering changes in the script.

SQLMI_GeoRestore.ps1 is available in the source code and most of the code is similar to the point-in-time restore activity.

In our geo-restore PowerShell script, we are using the same Restore-AzSqlInstanceDatabase command, but instead of using the -FromPointInTimeBackup parameter, we are using the -FromGeoBackup parameter.

The following is a...
