The backup file server stores backups from all the NSX Manager or Global Manager nodes. 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 can be found on each NSX Manager or Global Manager appliance at /var/vmware/nsx/file-store/get_backup_timestamps.sh. You can run this script on any Linux machine or on the NSX appliance. As a best practice, copy this script after installing NSX to a machine that is not an NSX Manager or Global Manager so that you can run this script even if all the NSX Manager or Global Manager nodes become inaccessible. If you need to restore a backup but have no access to this script, you can install a new NSX Manager or Global Manager node and run the script there.
