Preservation at Virginia Tech

Virginia Tech's digital preservation statement:

Digital Library Platform Diagram

This is a  diagram of the Digital Library Platform (DLP) for content at Virginia Tech University Libraries. This process is managed by the the Digital Libraries Department. Content produced by Clients and Content Managers is ingested into the DLP, where additional metadata is added to the metadata repository, identifiers are minted, checksums are calculated, and derivatives are created. The AIP is transferred to our local AWS instance, our local backup in Azure, and to one of our distributed preservation services. The DIP is transferred to our access platform.

Our Technologies


Our primary storage is in Amazon Web Services S3. Objects are replicated into our local, secondary preservation storage in Microsoft Azure. 

Virginia Tech is a member of both MetaArchive and Academic Preservation Trust (APTrust). Both organizations are aimed at long-term digital preservation storage, maintenance, and security. 

MetaArchive is an organization consisting of various libraries, universities, and other institutions geared towards long-term preservation. Their storage is based on LOCKSS (Lots of Copies Keeps Stuff Safe) caches, based at Stanford University. Archival units that VT controls on behalf of other institutions are ingested into MetaArchive.

APTrust is a consortium consisting of various higher education institutions for the purpose of preserving academic content and is based at the University of Virginia. 

See more information on our internal Storage Service through AWS.

Web Crawling

Archive-It is a web archiving service developed by Internet Archive that web crawls Virginia Tech's presence biannually. See our Web Archiving Program and the Web Archiving LibGuide for more information.
