EFFICIENT IMPLEMENTATION OF MULTIPLE DEDUPLICATION DATABASES IN A HETEROGENEOUS DATA STORAGE SYSTEM

Abstract:

A deduplicated storage system is provided according to certain embodiments that uses one or more mechanisms to assign the deduplication databases based on the type of the client device and automatically create a new deduplication database when critical thresholds are reached. In other embodiments, deduplication databases are further split into multiple database partitions. Based on a data block distribution policy, each data block is then further assigned to a particular database partition within the deduplication database to further improve efficiency and speed of the deduplication process.
