Can't be specific.
Example of the concept is here:
Hour 18: Miscellaneous Tools: remsh/rsh/rcmd/remote (Remote Shell)
Suggest you experiment with test files and directories which have unique names on both machines and checksum the files to be sure that the transfer method works. Most cross-platfrom cpio methods transfer the archive with ASCII headers and there is much variation in the syntax. Old cpio will not deal with large files (>2Gb) or large UIDs.

RCP(1) General Commands Manual RCP(1)
NAME
rcp - remote file copy
SYNOPSIS
rcp [-p] file1 file2
rcp [-pr] file ... directory
DESCRIPTION
Rcp copies files between machines. Each file or directory argument is either a remote file name of the form ``rhost:path'', or a local
file name (containing no `:' characters, or a `/' before any `:'s).
If the -r option is specified and any of the source files are directories, rcp copies each subtree rooted at that name; in this case the
destination must be a directory.
By default, the mode and owner of file2 are preserved if it already existed; otherwise the mode of the source file modified by the umask(2)
on the destination host is used. The -p option causes rcp to attempt to preserve (duplicate) in its copies the modification times and
modes of the source files, ignoring the umask.
If path is not a full path name, it is interpreted relative to your login directory on rhost. A path on a remote host may be quoted (using
, ", or ') so that the metacharacters are interpreted remotely.
Rcp does not prompt for passwords; your current local user name must exist on rhost and allow remote command execution via rsh(1).
Rcp handles third party copies, where neither source nor target files are on the current machine. Hostnames may also take the form
``rname@rhost'' to use rname rather than the current user name on the remote host. The destination hostname may also take the form
``rhost.rname'' to support destination machines that are running 4.2BSD versions of rcp.
SEE ALSO
cp(1), ftp(1), rsh(1), rlogin(1).
BUGS
Doesn't detect all cases where the target of a copy might be a file in cases where only a directory should be legal.
Is confused by any output generated by commands in a .profile, or .*shrc file on the remote host.
