I am in a process of upgrading NSX 6.2.4 by a customer in three locations deployed using VVD Deployment Toolkit. The NSX Upgrade itself went really smoothly. However, after the upgrade, we noticed that SFTP backup stopped working with an enigmatic error.

Syslog server is a must in all environments. It doesn't matter if you have 5 or 100 ESXi host or you use NSX or not. Today, we configure Syslog server for VMware NSX components. In my case it will be VMware vRealize Log Insight.
One of the components of modern and agile environments is Software Defined Network (SDN). Imagine that your Software Defined Data Center (SDDC) dies and you as Administrator of that environment have to recover it to state before crash.
