Abstract
Cloud-based digital library has achieved an efficient storage of massive digital resource, reduced the cost of management and maintenance, improved the sharing of information resources between digital libraries, and provided a convenient and rapid service for the users. Cloud storage architecture has the features of high reliability, high performance, high expansibility, etc. In order to ensure the security of information resources and the continuity of information service in Cloud-based digital library, the paper constructs disaster recovery system model of cloud-based digital library to ensure data security and business continuity. The model has dynamic scheduling, standard access interface, dynamic memory management and other functions.
