sparse file problem

["steve y" <steveymr@xxxxxxxxx>]

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
