To put things in perspective, recall that all the great libraries of antiquity–including the libraries of Alexandria and Pergamum–have disappeared completely. However, the world did not lose the knowledge they contained when they disappeared. Some of what was held in those libraries had been moved to other locations, either to be copied or because it was stolen. Even the fate of the libraries of antiquity shows that preservation relies not on the persistence of specific institutions, but on proper functioning of a system that includes redundancy and the sharing of knowledge across institutions. There is a great deal more progress to be made in this respect during this transition to the digital age, but the importance of doing so is unmistakable.
