AlwaysOn Availability Groups are part of an integrated solution, introduced in SQL Server 2012 with the goal of achieving the highest level of data availability and disaster recovery for organizations. Availability Groups grant DBAs the ability to automatically or manually failover a group of databases as a single unit with support for up to four secondary replicas. For additional information on availability groups, see the Microsoft document, Overview of Always On Availability Groups (SQL Server).
SQLsafe supports SQL Server Availability Groups and allows you to perform backup and recovery strategies on your primary and secondary replicas.
Keep in mind that an agent needs to be installed on all nodes in the availability group that will be considered for backups.
