Using the zip drives as raw-devices should work with 'tar' or 'cpio',
but: I don't know how long the filenames are allowed to be on BSD?
Maybe you will get problems with longer filenames than 14 characters?
If both system use different byte-orders, I would use 'dd' for swapping
the bytes (option 'conv=swab'). I did this a few years ago with a tar-
tape from a SGI which I had to read on our Intergraph-Server.
Example with 'cpio':
Writing:
$ cd <source-directory>
$ find . -depth -print | cpio -ovc > /dev/rdsk/<zip_device>
Reading (on the other machine):
$ cd <destination-directory>
$ dd if=/dev/rdsk/<zip_device> conv=swab | cpio -ivcmdu
| ^
if the byte-order is different <--+ |
|
-c option for compatibility.. --------------------+
Example with 'tar':
Writing with
$ tar cvf /dev/rdsk/<zip_device> *
Reading with
$ dd if=/dev/rdsk/<zip_device> conv=swap | tar xvf -
I hope this helps
