Like most other system parameters, the compression algorithm can be selected via sysfs. WebSliding-Window Codecs (LZ77, LZSS, LZO, DEFLATE, etc.) The basic idea with this class of algorithm is that runs of characters previously seen are replaced with a reference to said previously seen run. The reference itself is some sort of tuple containing the offset (i.e., starting position), the run length, and (optionally) the deviation ...
