When configuring application-consistent snapshots in a Nutanix protection domain for applications such as SQL, Oracle, and Exchange, it is critical to group all related VMs in the same consistency group within the protection domain. This ensures that the snapshot captures a consistent state of the entire application stack.
From theNutanix Enterprise Cloud Administration (ECA)course materials:
"A consistency group ensures that snapshots across multiple VMs are taken at the same time, maintaining application consistency for distributed applications. This is especially important for multi-tiered applications like SQL, Oracle, and Exchange, where data integrity depends on coordinated snapshot creation." Additionally:
"For application-consistent snapshots, leverage guest tools or volume shadow copy services (VSS) in Windows to quiesce applications, and configure the consistency group to include all relevant VMs." By creating one consistency group for all VMs comprising an application, the administrator ensures that snapshots represent a consistent state across the application components.
