I'm trying to copy a couple of DBM files from a disk to a RAM disk, one of the files is 500M the other quite small.
Some DBM implementations, if the filesystem supports doing so, will create files with "holes" in them; that is, the file may have arbitrarily long gaps in which there's no data. You can even have a file that seems larger than the disk it's stored upon.
Whether I use File::Copy or I roll my own copy by reading and writing the file the filesystem fills up... If I use system (cp from to) I don't have a problem.
It sounds as if your cp knows how to handle the holes, but File::Copy isn't so smart. It may be worth filing a bug report over this; even if File::Copy isn't fixed, its documentation should mention this.
