Since true CDP "backup write operations are executed at the level of the basic input/output system (BIOS) of the microcomputer in such a manner that normal use of the computer is unaffected", [2] true CDP backup must in practice be run in conjunction with a virtual machine [6] [9] or equivalent [10] —ruling it out for ordinary personal backup applications.
An effective backup strategy must also consider the cost of maintaining the ability to recover lost data for long periods of time.

However, in most situations, there is an inverse ...
