“Digital Preservation at CDL: Where We Are Headed”

From a University of California Curation Center (UC3) Post by Eric Lopatin:

At CDL, our digital preservation strategy hinges on offering trusted, reliable, low-cost preservation services to the University of California. Over the past year, we’ve been busy moving forward with these values in mind.


Over the past months, we have also been rethinking and evaluating key aspects of our approach to digital preservation. Some of these aspects include:

  • As an organization, we would like to introduce increased geographic separation across digital object copies, to ensure that our copies reside in locations with different disaster threats.
  • Along the same lines, we would like to introduce additional storage diversification across object copies, also in order to mitigate risk.
  • Though cloud storage is an integral part of Merritt, its use has prevented our team from being able to effectively lower the cost of preservation for UC campuses and affiliated organizations. We would like to find ways to dramatically lower our costs
  • We have not been satisfied with some of the technical limitations that come along with one of our storage solutions, particularly with regard to fixity checking, to confirm data in the repository remains unchanged, and unaffected by potential bit rot.
