Abstract
Described is a system for leveraging incremental backup metadata of a deduplication storage system to perform an efficient data restore. The system may reference metadata stored as part of incremental backup infrastructure to determine only the changes to the data that occurred subsequent to the restore point. As a result, the system may reduce data read processing by retrieving only the changed data from the deduplication storage system. Moreover, the system may reduce the required bandwidth for the restore by providing only the changed data to a target device of the restore. Data retained by the client system such as the current version of the data may then be overwritten with the reduced set of data to complete the restore. As a result, the system may perform an efficient restore by reducing read accesses and bandwidth requirements, and thus, improve overall restore performance.
