Use this parameter to choose which transfer program will copy the data across the network to another host. This parameter is used when you make backups to remote disks.
Syntax: stage_copy_cmd = rcp|ftp|scp
rcp means that the operating system remote copy command is used
ftp means that SAP implementation of file transfer protocol (sapftp) is used
scp means that the operating system secure copy command is used
An incremental backup to a remote disk is always made with ftp. In this case, this parameter is ignored.
