Abstract: Approaches for parallelized data deduplication. An instruction to perform data deduplication on a plurality of files is received. The plurality of files is organized into two or more work sets that each correspond to a subset of the plurality of files. Responsibility for performing each of said two or more work sets is assigned to a set of nodes in a cluster of nodes. The nodes may be physical nodes or virtual nodes. Each node in the set performs data deduplication on a different work set. In performing data deduplication, each node may store metadata describing where shared chunks of data are maintained in a distributed file system. The shared chunks of data are two or more sequences of bytes which appear in two or more of said plurality of files.

Abstract: Approaches for reducing a storage footprint for one or more files. A file type associated with a digital file is determined. A deduplication process is performed on the digital file based, at least in part, on the determined file type. The deduplication process may be performed differently on the digital file based on whether the digital file is an image or audio file, a compressed file, or a columnar file, for example. By considering the type of file being deduplicated, enhanced reductions in the storage footprint of the digital file may be realized.
