Digital preservation is an essential part of the digitization lifecycle and the lifecycle of born-digital resources. There are steps that can be taken to promote longevity of a digital asset throughout production, but generally, digital preservation comes when a digital asset is done being edited, and an access copy exists for continuous citation, research, and use. The main goal of digital preservation is to ensure that digital resources remain intact, accessible, and readable for as long as possible, regardless of changes in technology.
