For more information, see Use auto-failover groups to enable transparent and coordinated failover of multiple databases. 1. This way you can recover from data corruptions caused by human errors. Azure SQL Managed instances, Business Critical Tier and high availability. High availability disaster recovery (HADR) is an integral part of any organization’s data strategy. Identify, and optionally create, the logins that must be present in the master database on the new primary server, and ensure these logins have appropriate permissions in the master database, if any. built-in disaster recovery, no VMs to manage, etc) while removing almost all the limitations of Azure SQL Database (i.e. Read Scale-out Azure Site Recovery is a service that provides replication, failover and recovery options. Another option is to restore a database on any server in any Azure region using, Finally, you can quickly recover from an outage if you have configured either geo-secondary using. Identify alert rules that need to be updated to map to the new primary database. These preparation steps include: The recovery operation impacts the application. Make backups portable to on-premises SQL Server (unplanned) – Azure SQL DB Managed Instances are a future version of SQL Server, and we’ve never been able to restore from a newer version to an older version. Azure SQL Managed Instances take the difficulty out of managing a SQL environment. High availability, disaster recovery, and automated backups make Managed SQL easy to administrator and use. In an online world that operates 24 hours a day, going offline or losing customers' data cannot be tolerated. Disaster recovery acknowledges that there will be some interruption to service, but the aim is to resume normal operation as soon as possible. Failover Groups It enables the application to quickly restore availability in a different region in case of an outage. Use one of the following guides to fail over to a geo-replicated secondary database: If your application's downtime does not result in business liability you can use geo-restore as a method to recover your application database(s). Once initiated, the failover causes the secondary to become the new primary and ready to record new transactions and respond to queries - with minimal data loss for the data not yet replicated. With SQL Managed Instance, confidently modernize your existing apps at scale and realize up to a 238 percent return on investment. Even if you accidentally drop a database or someone drops your database as part of security attack, Managed Instance will enable you to easily recover the dropped database. If your application's downtime can result in business liability, you should be using failover groups. All clients connecting directly to the public endpoint would be able to use an alias instead of the real name of the instance. For a discussion of application design considerations for single databases and for elastic pools, see Design an application for cloud disaster recovery and Elastic pool disaster recovery strategies. Use auto-failover groups if your application meets any of these criteria: You may choose to use a combination of database backups and active geo-replication depending upon your application requirements. Sometimes an application must be taken offline because of planned maintenance such as an application upgrade. Auto-failover groups simplify the deployment and usage of geo-replication and add the additional capabilities as described in the following table: Although rare, an Azure datacenter can have an outage. Windows Azure keeps at least 3 copies of your SQL Database at all times. If you are running a SQL Server Failover Cluster Instance on premises and looking to migrate to Azure, you might be a little intimidated. To protect your business from data loss, SQL Database and SQL Managed Instance automatically create full database backups weekly, differential database backups every 12 hours, and transaction log backups every 5 - 10 minutes. Business continuity in Azure SQL Database and SQL Managed Instance refers to the mechanisms, policies, and procedures that enable your business to continue operating in the face of disruption, particularly to its computing infrastructure. Azure Site Recovery. Wait for service recovery The Azure teams work diligently to restore service availability as quickly as possible but depending on the root cause it can take hours or days. The time required for application to fully recover is known as Recovery time objective (RTO). This document provide the Best Practice guidence for the SQL-Managed Instance implementation considering a Disaster Recovery Architecture with a full Failover Group configured. Determine how you are going to redirect users to the new primary server, such as by changing connection strings or by changing DNS entries. For more information, see. Both primary and secondary databases are required to have the same service tier. When the datacenter comes back online the old primaries automatically reconnect to the new primary and become secondary databases. In this case, no action on your part is required. Auto-failover groups simplify the deployment and usage of geo-replication and adds the additional capabilities as described in the following table. For more information about changing connection strings, see the appropriate development language for your connection library. Because your recovered database resides in a different server, you need to update your application’s connection string to point to that server. To verify the current… That, in addition to bare-metal and Hyper-V server replication, provides a flexible and powerful tool for protecting server infrastructure. The entire process can be implemented by Azure Resource Manager configuration, Powershell, ARM Templates or Infrastructure as a Code using Terraform. After recovery from either recovery mechanism, you must perform the following additional tasks before your users and applications are back up and running: If you are using a failover group and connect to the databases using the read-write listener, the redirection after failover will happen automatically and transparently to the application.

Learn about options, recommendations, and tutorials for recovering from disruptive events that could cause data loss or cause your database and application to become unavailable. If your application can tolerate significant downtime you can simply wait for the recovery to complete. Manual database failover refers to failover of a single database to its geo-replicated secondary using the unplanned mode. Depending on your application tolerance to downtime and possible business liability you can consider the following recovery options. You can use automatic database backups to restore a database to a point in time in the past. For most databases the restore operations takes less than 12 hours. If you are using the automated backups with geo-redundant storage (enabled by default), you can recover the database using geo-restore. This architecture is a bit complex because it uses quite a few different technologies all working together. Use the Get Recoverable Database (LastAvailableBackupDate) to get the latest Geo-replicated restore point. The additional cost of active geo-replication is lower than the potential financial liability and associated loss of business.
