Atom, You are correct. The "value" of the data is in the cost associated with reproducing it, or lost productive time or potential loss of business that may result while the data is unavailable. That's actually exactly what I said...er...four or five responses, ago. The "value" of the data is going to be a very subjective measurement that the owners of the data will have to make. The "churn" of the data does not influence the impact of loss of the data. What it does impact is the likelihood of an undesirable event. In particular, it impacts the likelihood that the data which is backed up might not be sufficient to restore the desired state of the data...which could be either because all of the backups are too recent...or all of the backups are too stale. So as I see it, the rate of change of the data is completely independent of the subjective valuation of that data.
That brings up another point that I can use, though. Some of this may be data that was collected from several sources. Even if the data doesn't have to be recreated...it still would need to be gathered from the original sources, again. So you still have a good point.
