my biggest complaint with all this is the total lack of paragraphs.

myself i offer a total imaging of a system for $35. and the customer can have the dvd or cd set. if things go bad then its simple to apply the image (another $35 for sitting and watching it run).

if they lose it then too bad...its gonna cost em when things go south. done once a month...or whenever they want...they are good for a recovery and lose only whatever was saved between backups.

i also will set up an auto backup to cd or another drive if they want . its up to them to make sure it runs.
