These files, if changed, are backed up into conf-backup.<date>.tar.gz file (<date> is archive date), and should be restored manually, if necessary.
The following is a list of some configuration files.
NetFlow Intergrator URI and other parameters
Default self-signed certificate for X509 authentication
