Thanks, Jack. We do have an existing backup system, which is what we are having to replace. I can certainly ask the backup administrator to try to help produce some of these statistics, but I don't know how much visibility he has into the current backup systems database.
Remember, though: The point of this is not to determine a suitable backup capacity. The point is to quantify the risk exposure of undesirable data-loss events, preferably into a monetary value that can then be compared to the expense of purchasing hardware/software/maintenance for a backup solution.
