dvbackup - 1:0.0.4-11 main

Dvbackup hides the data it receives on standard input in a perfectly
legal DV (digital video) stream. This allows you to use your DV camcorder
and your DV cartridges as a potent mass storage system. Obviously, your
system and your camcorder have to be connected via IEEE1394 (aka Firewire,
iLink).
.
Current digital camcorders can save approximately 13 GB of data on those
tiny DV cartridges at a speed of 3.6 MB/sec. That's faster than most
DAT streamers which only work at 1 MB/sec or less. dvbackup can not use all of
the data, but 10 GB should be good enough for everyone.
.
To bring the data on tape, you have to use an additional utility, called
dvconnect, which is included in libdv-bin.
