A system and method for maximizing network throughput by dynamically tuning the number of connections used during data transfer with various cloud providers. This adaptive tuning of the network connections is based on the accepted request rate for the cloud provider, the outstanding transfer capacity of the cloud network as derived from the network bandwidth, and errors and retry requests from the network and the cloud provider.

Maximizing network throughput between deduplication appliances and cloud computing networks

A method, article of manufacture, and apparatus for performing backup operations using a deduplicated storage system is presented. A data segment can be received at a deduplicated storage system. A fingerprint can be calculated for the data segment. The fingerprint and the offset can be stored in a reference cache on the deduplicated storage system. A metadata segment can be loaded from the deduplicated storage system. The metadata segment can be updated to include the fingerprint. Backup operations may include storage and management using a tree structure.

Method to improve the I/O performance in a deduplicated storage system

A method, article of manufacture, and apparatus for backup operations. A read request is received for a data segment at a deduplicated storage system. The data segment is determined not to be in a data cache on the deduplicated storage system. A data segment reference for the data segment is determined to be in a data segment reference cache on the deduplicated storage system. The data segment is read from a persistent storage using the data segment reference.
