+.BI \-y
+Compress every block to be written to the tape using the lzo library.
+This doesn't compress as well as the zlib library but it's much faster.
+This option will work only when dumping to a file or pipe or, when dumping to
+a tape drive, if the tape drive is capable of writing variable length blocks.
+You will need at least the 0.4b34 version of
+.B restore
+in order to extract compressed tapes. Tapes written using compression will not
+be compatible with the BSD tape format.
