Restore Types

As you know, the restore command isn't supported in Azure SQL Database, but the PITR can be performed using the Azure portal, PowerShell, Azure CLI, or Azure SDK. The PITR uses the automatic Full and Log backup.

The SQL Database can be restored at any time within the retention period, which is a maximum of up to 35 days.

The database can only be restored on the same Azure SQL Server as the original database with a different name. If you are restoring a database using PITR to recover from a corruption issue and wish to use the restored database as the production database, you will have to rename the database accordingly...
