Dynamic data compression selection
First Claim
1. A method for data compression, the method comprising:
- receiving uncompressed source data at a data compression system from a data storage device, the uncompressed source data comprising a set of compressed data chunks;
selecting a first compression algorithm to compress a first subset of the set of data chunks;
compressing the first subset of the set of data chunks using the first compression algorithms;
selecting a second compression algorithm to compress a second subset of the set of data chunks;
compressing the second subset of the set of data chunks using the second compression algorithm; and
transmitting the compressed first subset of the set of data chunks and the compressed second subset of the set of data chunks to a data target.

Abstract
Aspects of dynamic data compression selection are presented. In an example method, as uncompressed data chunks of a data stream are compressed, at least one performance factor affecting selection of one of multiple compression algorithms for the uncompressed data chunks of the data stream may be determined. Each of the multiple compression algorithms may facilitate a different expected compression ratio. One of the multiple compression algorithms may be selected separately for each uncompressed data chunk of the data stream based on the at least one performance factor. Each uncompressed data chunk may be compressed using the selected one of the multiple compression algorithms for the uncompressed data chunk.
