VMSTPC, by Brian Nelson

VMSTPC copies tapes to disk resident container files or copies container
files to tape, handling I/O so as to produce a format independent copy
of a tape. VMSTPC uses AST driven, multibuffer I/O to keep the I/O subsystem
busy (and keep tape streaming) so that it typically can copy tape far
more quickly than any other technique. Many controls and options exist, so
read vmstpc.hlp for more complete information.
