摘要：
Each year destructive events might cause loss of data in members of an archival federation. This paper provides a 'back-of-the-envelope' model for the fraction of the federated data collection that survives after a certain number of years. It also discusses some simple parameterizations of factors that contribute to the trade offs between cost and survival of information.
