Data loss prevention starts with the creation of a digital object. However, methods to minimize the loss of digital data are often ignored, the use of metadata structures embedded in digital objects from the outset thereof are recommended as a starting point towards good preservation principles.
The need to create awareness on the issue of digital preservation was promoted by the authors at various occasions during 2008 as the number of incidents of data loss and costs involved continue to be of concern to conservators. Whether the loss occurs by a malicious attempt, or an inadvertent mistake, it can be diminishing either personally or to the institute/company where it occurs.
Digital objects should be archived with metadata about the object and the creation thereof. Metadata need not necessarily be structured and controlled when used by individuals or small groups for preservation of self owned data. The metadata content however, should describe the object, the method of creation and technologies used in the creation. All changes to the document should be captured in the preservation metadata.
Future access to digital content does not only depends on one preservation method but on a sequence of strategies and methods applied to the digital content. This paper discusses the use of metadata principles and the implementation of tools for the preservation of documents stored on personal computers.
