==In data deduplication, data synchronization and remote data compression== In [[data deduplication]], [[data synchronization]] and remote [[data compression]], Chunking is a process to split a file into smaller pieces called chunks by the chunking algorithm. It can help to eliminate duplicate copies of repeating data on storage, or reduces the amount of data sent over the network by only selecting changed chunks. The Content-Defined Chunking (CDC) algorithm like [[Rolling hash]] and its variants have been the most popular data deduplication algorithms for the last 15 years.<ref>{{cite conference |title=FastCDC: a Fast and Efficient Content-Defined Chunking Approach for Data Deduplication |date=2016 |url=https://www.usenix.org/system/files/conference/atc16/atc16-paper-xia.pdf |access-date=2019-12-10 |conference=USENIX ATC β16 }}</ref>
