sparse file problem

[steve y]

Hi,

I have a 2TB sparse file on a xfs partition whose actually size is 2MB. I
want to copy it to different location on the same partition.
I am using rsync -S to do so, however it takes very long to copy. Does a
sparse-aware file copy utility exist. If not, can i write one using xfsctl.
I need some pointers in that direction.

Thanks,
Steve
