Holey files, Batman!

[William E. Davidsen Jr]

  Your original idea will work for copying sparse files from disk to
disk.  The problem comes in copying them to a backup device and
reloading them.  I know of no program to do this, although it would be
easy to have the reload program write a sparse file if blocks of zeros
were encountered. 

Is there a problem with this? That is, is there a way to tell a sparse
file from a file with a lot of zeros?
