About SQL Server Always On availability groups

Backup Exec supports SQL Server Always On availability groups. The Always On availability groups feature in SQL server is a high-availability and disaster-recovery solution. Backup Exec supports backup and restore of databases, which are part of Always On Availability groups.

The Always On availability groups feature maximizes the availability of a set of user databases by providing a fail over environment. The databases, known as availability databases, fail over together. An availability group supports a set of read-write primary databases and one to eight sets of corresponding secondary databases. Optionally, secondary databases can be made available for read-only access and/or some backup operations.

Always On delivers capabilities such as, fail over cluster instances, multiple secondary, readable secondary, failover of group of databases (instead of entire node), and connection director. This feature can work in various customer environments with different requirements. An availability group fails over to an available replica.
