The backup file server stores backups from all the NSX Managers. To get the list of backups so that you can find the one you want to restore, you must run the get_backup_timestamps.sh script.
The script is located on an NSX Manager. The full path name is /var/vmware/nsx/file-store/get_backup_timestamps.sh. You can run this script on any Linux machine or NSX-T Data Center appliance. As a best practice, you should copy this script after installing NSX-T Data Center to a machine that is not an NSX Manager so that you can run this script even if all the NSX Managers become inaccessible. If you need to restore a backup but have no access to this script, you can install a new NSX Manager and run the script there.
