One obvious example - file had non-zero block (and so it consumed real storage) which was later overwritten by zeroes. It will continue to consume real block on source, but on destination it is replaced by hole (no storage consumption).
even with checksum control??
checksums will see zeros in both cases.
really curious
Think of it as compression, the files are the same, but compressed. -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" at Telcontar)
