I Say Emulate; He Says Migrate - Are Emulation or Migration Feasible Preservation Strategies?

Andrew Stawowczyk Long, David Pearson


Prepared by Andrew Stawowczyk Long and presented by David Pearson at the IIPC (International Internet Preservation Consortium) Open Day, San Francisco on 7 October 2009.

Arguably, we must take some sort of action to maintaining access to web collections.  Therefore, the appropriateness of particular preservation strategies for web archives is important for many collecting institutions.

As there are many, sometimes conflicting views on what methodologies would be the most effective in long-term preservation, it is important to try to figure out the practical aspects of most promising ones.

Currently, it seems to us that the only long-term sustainable methodologies are emulation, migration or combination of both. This project attempted to examine these methodologies on a particular web archive at the NLA. However, the conclusions presented here hopefully have utility for other archives.
