Re:You've already got tape backups (Score 1)

Depending on the video editing software (like adobe premiere), you can log your in and out points from the raw video tapes to a very small data log file. With this log file you can resore your video project automatiically any time in the future so you don't have to waste so much hard drive space. The process is automatc after the in and out points are logged. If you are really paranoid you can make a backup copy of your original dv tape and store it in a safety deposit box.
