Abstract: Embodiments of this invention provide primary magnetic disk data storage capacity to clients while at the same time making sure that client data is replicated locally and at an offsite location to protect from all forms of data loss.

Abstract: The present invention provides systems and methods for transferring a set of files. Metadata and stub files associated with the set of files are received at a destination fileserver, a location component in the destination fileserver is updated to maintain a list of repository nodes associated with each file in the set of files, and each stub file is replaced with the full content of the file associated with the stub file. The replacing includes receiving a client request for a specified file in the set of files and replacing the stub file associated with the specified file with a full content of the specified file if the full content of the specified file has not yet been transferred. Replacing the stub file associated with a requested file is a higher priority task than replacing a stub file associated with a non-requested file.

Abstract: A method and apparatus for providing information outsourcing, including a storage node located remotely from an information outsourcing enterprise. The enterprise communicatively couples to the storage node to transfer information between the enterprise and the storage node in real-time to enable primary storage, static and dynamic mirroring, backup and disaster recovery of enterprise information. The system of the invention provides an enterprise user interface for enabling the enterprise to monitor its storage usage. The enterprise interface also enables the enterprise to expand or contract the storage space reserved by the enterprise at the storage node The system of the invention packages outsourcing services into service level agreements. Multiple storage nodes can be communicatively connected to enable the system to transfer information between them.
