Abstract

The techniques provided in this application relate to data deduplication, and in particular, but not exclusively, to methods and systems for determining an efficient optimal size of a data block for backing up a data source. Additionally, a system for identifying duplicate data in data backup applications is also provided in this application.

Description

[0001] This application claims priority to U.S. Provisional Patent Application Serial No. 13 / 802,167, filed March 13, 2013, which claims Serial No. 61 / 708,255, filed October 1, 2012 and filed on Priority to US Provisional Patent Application Serial No. 61 / 708,295, filed October 1, 2012, the disclosure of which is hereby incorporated by reference in its entirety. Background technique [0002] Data deduplication is a data compression technique that reduces the amount of data by identifying and eliminating redundant data. The earliest deduplication technology for "single instance storage" is deduplication based on file granularity. In file granular deduplication, duplicate copies of the same file are detected based on content and only one copy of the file is stored on disk, whether or not the duplicate copies have the same name. However, the technical inefficiency of file granularity is related to comparing data at such a process level: for example, if a single word is added to a...
