GNU du has --apparent-size which reports the "file size" instead of how
much disk space it uses.. compression and sparse files will make this
differ, and you can't really tell them apart.

[zfs-discuss] Question about du and compression
Hi all Is there a good way to do a du that tells me how much data is there in case I want to move it to, say, an USB drive? Most filesystems don't have compression, but we're using it on (most of) our zfs filesystems, and it can be troublesome for someone that wants to copy a set of data to somewhere to find it's twice as big as reported by du.
