How reliable is the Internet itself?
The only FTP problem we've ever experienced, where a file received was
NOT identical to the file sent, was (finally) traced to a defective
switch. At random, bytes were trans-positioned within a block such that
the checksum for the block remained unchanged. That was a real
"head-scratcher".
If the files you need to move are sufficiently important to you, do
both.
