Mounting to clustered Instances
When mounting to clustered instances, Protector will mount the block-based backup as traditional clustered disks and add them as a dependency for the selected target SQL Server instance. This ensures that the instance will still be able to failover, and the mounted databases remain online in case of a cluster failover.
Mounting to availability groups
It is impossible to mount directly to availability groups as this would imply replicating the mounted database as well. However, mounting to an instance hosting availability group replicas is possible.
Prerequisites
- A block-based backup of a Microsoft SQL Server is available.
- A Microsoft SQL server node exists for the target SQL Server instance.
- The target node must not be of type Availability Group. However, selecting nodes and instances hosting an Availability Group replica is okay.
- Credentials for the SQL Server instance are available. Please refer to Microsoft SQL Server User Privileges for more details.
- The target instance supports the internal database version of the databases in the backup.
- All nodes of the target instance are up and running.
- When mounting to a clustered instance, the instance must consist of a minimum of two nodes. Mounting to single-node clusters is not supported.
