To support network functionality in the case of a vSphere with Tanzu workload outage, back up and restore NSX-T Data Center.
To backup and restore NSX-T Data Center, it is assumed that 3 NSX Manager Nodes are deployed, and there is an HA VIP configured for access to the NSX Management Plane. In addition, there are at least 2 Edge Nodes deployed with an HA VIP for the Edge Nodes. For more information, see Configuring NSX-T Data Center for vSphere with Tanzu.
NSX-T Backup and Restore
NSX-T Data Center provides in-product backup and recovery that supports backup and restore of the NSX Manager Nodes and objects. For more information, see Backing Up and Restoring NSX Manager in the NSX-T documentation.
