Best Practices for Protecting Microsoft SQL Server Failover Cluster Instances with RDMs

Zerto supports continuous data protection (CDP) for Microsoft SQL Servers (MSSQLs), including Failover Cluster Instances (FCIs). When protecting an MSSQL Failover Cluster with Zerto, the key consideration is consistency of the database raw device mappings (RDMs) and the cluster itself. This paper looks at the best practices for replication, failover testing, live failovers, and failback, in a particular scenario:  disaster recovery as a service (DRaaS).
