(...)Since this whole-file checksumming of all files on both sides of the
connection occurs in addition to the automatic checksum verifications that
occur during and after a file's transfer(...)

So you are saying the --checksum option uses a whole-file checksum of all
files on both sides...

... on the other hand you are saying that this happens anyway with the
automatic checksum verification, regardless which options you use?!


Then there is also this block-sum verification
(...) Then the local file is read and a checksum is generated for the
block beginning with the first byte of the local file(...)

I am a little confused now. But i am sure i am just about to put all
puzzle pices together. :-)


Thanks, Mario
