This enumerated field selects which file-transfer protocol a recurring configuration-export policy that periodically exports the full UCS configuration (not backup state) to a remote server uses to reach its remote destination server. The choice here determines exactly which network port and authentication mechanism a CfgExportPolicy needs open and working between the UCS domain's management network and the destination server — an admin who moves a backup target behind a firewall needs to make sure the matching protocol's port is allowed. Supported values include ftp, tftp, scp, sftp, and http, with scp/sftp being the common choice where encryption in transit matters.
