At the request of the Da Dog, lets discuss the hardware and activity of backup/archiving? At one time it was simple. The analog multitrack tapes and the 2-track master tapes were put in a box and stored on a shelf or in the closet along with with the track sheets and mabe a few other notes. I don't remember ever really worrying or doing safety copies until DAT machines and then with ADAT tapes. Now it is a whole other ball game and a very time consuming process of backup/archiving in multiformats is a necessary chore to be done. I myself, pretty much now rely on several safety copies of CD-R (in PCM or data or both) and use DAT for a temp storage that I recycle after the client has blessed and paid off the bill/invoice. I don't believe or trust hard disks as being a long term proper backup and storage format. I also don't have much faith in CD-R either, but it is the most easy and cheapest way to do both data and real time playable backup/archive and if I make half a dozen copies it takes most of the worry away for the short and mid term. As for responsability, unless I'm paid a specific and separate archiving and storage fee, once I'm paid I am no longer responsable. And if you bring me back something for rework and I have to restore it back to my hard disks or tapes, there is a separate fee to do that. So let everybody chime in on how and what your doing for backup/archiving as well as the formats and hardware your using to do so. We might as also discuss who is responsable and what they are responsable for as well.
