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.

5. Restoration

In the previous chapter, we talked about performing database backups for Azure SQL Database and Azure SQL Managed Instance. Similar to a database backup, a restore is another housekeeping activity that a DBA performs, whether to move or copy a database from one server to another or to recover from an outage or an accidental update/delete operation. In this chapter, we'll look at different ways to restore an Azure SQL Database and an SQL Managed Instance database.

Azure SQL Database and SQL Managed Instance have the following restore options:

  • Point-in-time restore
  • Restore from long-term backup
  • Restore a deleted database
  • Geo-restore a database
  • Import a BACPAC – only for Azure SQL Database

Figure 5.1 shows the types of backup available with Azure SQL Database, the different restore options, and the ways to restore a database:
