2015 Priority - Better Backup and Recovery For the DBA


 Last week we reviewed the first critical step to SQL Server database management – assessing your current environment to develop a map guiding a management overhaul. Having the most comprehensive view of the database helps inform design and decisions on backup and recovery policies – the second essential step in optimized management.

SQL Server features high-availability capabilities including:

  • AlwaysOn Failover Cluster Instances: Provide server-instance level redundancy
  • AlwaysOn Availability Groups: Enterprise-level solution to maximize availability for one or more user databases
  • Database Mirroring: Increase availability of a SQL Server database by supporting almost instantaneous failover.
  • Log Shipping: Functioning at the database level, provides automated backup and restore.

Since high-availability capabilities exist, some DBAs get tripped up thinking disaster recovery is covered as a result. This is a common misconception.

In actuality, high availability and disaster recovery are not synonymous.

High availability refers to the processes put in place to ensure applications and services running on a database remain up, while disaster recovery refers to retaining the data within SQL Server in the event of an outage.

The need for a disaster recovery prompts DBAs to review their backup and recovery strategies. Backup and recovery go hand and hand. There is no way to simply implement a recovery strategy, which typically takes a lot of effort and a multi-phase approach, without first assessing backup processes.
