NSX-T is a critical infrastructure component and it is crucial to have a working backup and restore plan. With complex products, the backup and restore strategy gets more complicated. When working with Virtual Machines, the backup is usually done with VMware Snapshots, which is super convenient. Unfortunately, with the complexity of NSX-T which has many components like clustered Managers, Transport Nodes, and ESXi Kernel Modules, you can't use snapshots as a backup strategy.
This article provides an overview of how to backup NSX-T, and how the restore is done properly.
