In the previous case, Veeam didn't handle the FSCTL_DUPLICATE_EXTENTS_TO_FILE attribute in SMB correctly. As stated in the post I linked "This great new feature allows Windows to directly ask the NAS to clone a portion of an existing file, instantaneously and without consuming any extra space."

one more question about SMB3 feautures om NTRG: how to downgrade SMB protocol level to SMB2 at 6.9.3 OS?
