Explanation:
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 strings 1 . You can also use active geo-replication as an alternative, but you will need to update the connection strings manually after a failover 2 .
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.
* Select Failover groups in the left menu and click on Add group.
* Enter a name for the failover group and select West US 3 as the secondary region.
* Click on Create a new server and enter the details for the secondary server, such as server name, admin login, password, and subscription.
* Click on Select existing database(s) and choose db1 from the list of databases on the primary server.
* Click on Configure failover policy and select the failover mode, grace period, and read-write failover endpoint mode according to your preferences.
* Click on Create to 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 Azur e 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 -Typ eName 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 -FailoverPo licy 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.
