Why do you need this.
If you work with VMware NSX on daily basis you should care about Backup & Restore procedure. According to VMware you can schedule NSX Manager backup and think you are on safe side but restore procedure requires to perform full NSX Manager restore and then redeploy some or all NSX components. This will overwrite the whole your current network configuration and as result is not suitable for partial restore (several components only) on Production environments.
VMware example:
The way you can do it with PowerNSX.
So my idea was to schedule the task which is going to read all ESGs and DLRs configuration parameters and store it in human readable text files. The parameters are saved in the same order as you use them during manual deployment for new ESG/DLR so you don’t need to scroll forward and backward to find necessary parameter. In this case you can re-deploy any Edge or DLR manually with NSX GUI to restore network configuration. Also exported files can be used as reference to track the configuration and changes back in time which could be helpful sometimes.
This post is the Part 1 of my blog, it contains the script I wrote for ESGs export. Next post will be for DLRs export.
How to use this script
You just need to replace vCenter name for variable “$vCenterServerName” by vCenter FQDN or IP specific to your environment.
After start the script asks for vCenter credentials, creates the subfolder in format “ESGs-Config-Export-dd_mm_yyyy-hh_mm”, reads list of all ESGs with parameters and stores in text files, separate file for each ESG in format “Config-for-ESG_esgName”.
