You need to cpio to the raw device when going over multiple volumes.

For SysV/386, use:

cpio -ocvmB >/dev/rdsk/f0
                  ^ raw disk device
                       ^floppy 0

Reading back:
cpio -icvdmB </dev/rdsk/f0

If you want to start on a disk that is NOT the first one, use the 'k' option.
cpio -icvdmBk </dev/rdsk/f0

The 'k' option will ignore the header info.

Use the 'u' option if you want to overwrite files with the same name.


For 3B2, the raw floppy device is '/dev/rdiskette'
