But if anyone wants to implement it, cp like behavior is not a good choice.
It can't detect gaps in file and skip them. You have this with core files,
for example. The size of a file is huge, but it actually takes a modest
amount of disk space, since most of the file are zeros and pages with
zeros only are not stored on disk. Cp will create files that really have
all those zeros.
