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!
