You probably have a large sparse file on the client that isn't handled
very well by the copy mechanism. On unix filesystems you can seek past
the end of a file and write, creating a file that appears to be very
long but without using the intermediate space where nothing has been
written. In particular, many 64-bit linux versions have a
/var/log/lastlog file that appears to be 1.2 terabytes in size as an
artifact of indexing it by uid numbers and using -1 for the nfsnobody
id. It's generally not important to back this file up, so if that is
the problem you can just exclude it.
