+The dump level (any integer). A level 0, full backup, guarantees the
+entire file system is copied (but see also the
.B \-h
option below). A level number above 0, incremental backup, tells
.B dump
to
copy all files new or modified since the last dump of a lower level. The
-default level is 9.
+default level is 9. Historically only levels 0 to 9 were usable in
