BACKCOPY usage is the same as DOS copy command.
BACKCOPY is designed to allow copying files in the background with a
multitasking operating system (such as Microsoft Windows). When the DOS COPY
command is used, it consumes system resources to the extent that all other
processes nearly stop. Even the foreground process will typically be unusable
while the copy is running. BACKCOPY gives up time slices so that other
processes may continue normally while the copy is going on.
