Simplest is not always best. A good backup/recovery plan has to take into consideration costs, time and resources. Often this includes the use of full and either incremental or differential backups. Example, running a complete full backup of company data every night is not needed, a weekly full backup with daily differentials is fine. But in doing so, resources must be taken into account. While 2 external USB drives are adequate, it costs more in time and the human element in remembering to switch the drives and taking them home (they are rotating off site aren't they, or at least into a electronic media rated fire safe.) Better would be to use the 2 external USB drives for weekly full backups, and then use a REV or JAZZ or flash drive for daily differentials, but that requires additional resources and cost. In other words, a backup/recovery plan is specific to each business depending on costs (lost time, budget, resources, business down time) time (some one has to change tapes and/or CDs and/or drives and who covers if that person is not there) and resources.

Also backup with verify and done full every night. I think a full 7 GB a night is a little over kill. Don't you think so?
