To configure a disaster recovery solution for db1, you can use the failover groups feature of Azure SQL Database.Failover groups allow you to manage the replication and failover of a group of databases across different regions with the same connection strings1.You can also use active geo-replication as an alternative, but you will need to update the connection strings manually after a failover2.
Here are the steps to create a failover group for db1 with the secondary server in the West US 3 region:
Using the Azure portal:
Go to the Azure portal and select your Azure SQL Database server that hosts db1.
SelectFailover groupsin the left menu and click onAdd group.
Enter a name for the failover group and selectWest US 3as the secondary region.
Click onCreate a new serverand enter the details for the secondary server, such as server name, admin login, password, and subscription.
Click onSelect existing database(s)and choose db1 from the list of databases on the primary server.
Click onConfigure failover policyand select the failover mode, grace period, and read-write failover endpoint mode according to your preferences.
Click onCreateto create the failover group and start the replication of db1 to the secondary server.
Using PowerShell commands:
Install the Azure PowerShell module and log in with your Azure account.
Run the following command to create a new server in the West US 3 region:New-AzSqlServer -ResourceGroupName <your-resource-group-name> -ServerName <your-secondary-server-name> -Location 'West US 3' -SqlAdministratorCredentials $(New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList '<your-admin-login>', $(ConvertTo-SecureString -String '<your-password>' -AsPlainText -Force))
Run the following command to create a new failover group with db1:New-AzSqlDatabaseFailoverGroup -ResourceGroupName <your-resource-group-name> -ServerName <your-primary-server-name> -PartnerResourceGroupName <your-resource-group-name> -PartnerServerName <your-secondary-server-name> -FailoverGroupName <your-failover-group-name> -Database db1 -FailoverPolicy Manual -GracePeriodWithDataLossHours 1 -ReadWriteFailoverEndpoint 'Enabled'
You can modify the parameters of the command according to your preferences, such as the failover policy, grace period, and read-write failover endpoint mode.
These are the steps to create a failover group for db1 with the secondary server in the West US 3 region.
