AppSync communicates with the SQL Server virtual server rather than individual nodes. The AppSync Host Plug-in is required on each of the cluster nodes first, the virtual server must be registered.
To begin protecting databases in clustered instances, follow these steps:
- Install the AppSync Host Plug-in by adding each node of the cluster to AppSync, or by first manually installing the software on each node and registering the host within AppSync. This step must be completed before moving to the next step.
- Add the SQL Server virtual server to AppSync. AppSync discovers only the Clustered SQL Server instances and clustered file systems if applicable.
The SQL Server virtual server is the IP address or FQDN name that is registered as an IP address or network name in the cluster registry, respectively, and is directly associated with the SQL Server Role.
- Enter the SQL Server connection settings by clicking the SQL Server instance on the Microsoft SQL Server protection page. Use either SQL Server or Windows authentication as applicable. AppSync discovers the user databases that belong to the instance.
- Subscribe databases to a service plan to protect them, or subscribe the User Databases folder to a service plan to dynamically protect user databases. AppSync protects any new user databases and stops protecting any deleted or offline databases using this method.
Note: Manually delete any AppSync copies of deleted databases.
