I am copying from an XFS filesystem to a NTFS (CIFS) file system to a Samba share. Unfortunalty NFS is not an option.
While I haven't used rsync from Linux to NTFS/CIFS, I would strongly suspect that the Windows file system is the real culprit. It doesn't have the same capabilities, so rsync may be trying to 'check' things, and (since it can't), assumes the file needs transferring.
But based on what you've posted, what verification are you seeing, where?? All I can see is rsync sending a file...was that file already present?

There is also a non default option of checksum. With it sending and receiving files are checksummed in their respective systems and if they don't match then only the files are updated
Are you not reading the original posts??? The OP clearly stated they are performing the rsync WITHOUT the checksum...so telling them to do it that way is pointless.
