ABSTRACT:
An integrated NAS/CAS system is disclosed. The system includes a view management program that is able to provide a NAS view and a CAS view of files to NAS and CAS clients. The system applied NAS or CAS features to stored files according to the view status of the file. Migration of files from NAS to CAS for archiving may be done without transmitting the file, thereby reducing bandwidth requirements and increasing security. CAS features, such as retention policy and metadata can be added to the file when its view is changed from NAS to CAS.
