While I can create multi-volume backups to my zip drive by using the
following syntax:

tar -M -L 85000 -cvf /dev/rsd1 -b 20 *

This backups the current directory and below with a block size of 20 512
byte blocks.
tar asks for a new disk after 85000 1024 bytes written. So far so good.

Trouble is that I can't figure out how to retrieve the archive without
losing any files that cross a volume boundary.

The following line retrieves each disk seperately but not the entire
archive.

tar xMvfb /dev/rsd1 20

any ideas would really help.
