Embodiments of the present invention are directed to Web-Services-based data backup and data-archiving applications that provide remote data backup and data archiving to private individuals, small businesses, and other organizations that need reliable, secure, geographically remote, and cost-effective data backup, data archiving, and backed-up and archived-data retrieval. In one embodiment of the present invention, a private or small-business client contracts with a service provider for data-backup and data-archiving services. The service provider, in turn, contracts with a remote data-storage facility to provide secure, reliable data backup and data archiving to the personal or small-business client. A client-side application is downloaded to the client computer and configured to allow the client to store locally encrypted data at the remote, data-storage facilities. Neither the service provider nor the data-storage facility can decrypt or otherwise access the information stored by the client. In addition, the encryption key or encryption keys used by the client to encrypt the data for remote storage are securely stored at the remote, data-storage facility for subsequent recovery by the client, should the client suffer damage or loss to a local computer system. However, the client encryption key is stored in a doubly encrypted fashion, preventing access to the client's encryption key by either the service provider or the data-storage facility. Certain embodiments of the present invention also provide local indexing for remotely stored, encrypted data and efficient storage of updates to already remotely stored data.

A method dramatically reduces the amount of data to be stored and transferred in a networked storage system. Preferably, the network storage system provides continued data protection through mirroring / replication, disk-to-disk backup, data archiving for future retrieval, and Information Lifecycle management (ILM). The idea is to leverage the parity computation that exists in RAID systems. By caching, transferring, and storing data parity or delta bytes of changes on a block as opposed to data block itself, substantial data reduction is possible without using sophisticated compression algorithms at the production side to minimize performance impacts upon production servers. Data can be computed using the parity / delta and previously existing data at mirror side, replication side, backup storage, or at retrieval time upon events such as failures or ILM operations.

A highly reliable data archival and retrieval method that enables fine grained control over data availability is implemented across a Quality of Service driven archival system, configured to fragment the data into data and parity chunks for storing onto the storage node. The technique employed by the archival system enables files to be read without having need to access any metadata, thereby tolerating complete loss of such metadata. Further, the Quality of Service driven system architecture improves upon the system performance and throughput by means of a storage node regeneration process which ensures balanced load on participating storage node during various storage, retrieval and regeneration operations.

A data archiving system according to the invention performs offline backup of data stored at a target system connected to a network. To minimize downtime of the target system, the data is archived at a low level of abstraction, e.g., at the block level, rather than at the file system level. The offline backup is accomplished by closing open files and application, and rebooting the target system with an archiving operating system that manages the data backup process. After the target data has been archived, the target system is rebooted with the normal operating system.
