Briefly, the client 'tees' the tar output to another invocation of tar with the -t (table of contents) option, which lists each file in the dump, one per line. That information is sent to the server in a stream parallel to the data stream, where the dumper writes it to the gnu-tar index files directory, possibly compressing it first. I hope that helps!
