Lossless compression is fine, but reformatting and storing received data for a small percentage gain in space in a large database will cause more issues than it's worth.

无损的压缩虽好，但是为了在大型数据库中节省少量的空间而重新格式化和存储接收的数据，会导致更多问题，实属不值。

Bonus: Lossless data compression cannot guarantee compression for all data input files.

额外收获：无损耗数据压缩不能保证对所有输入的数据文件进行压缩。

The gzip compressor is based on the DEFLATE lossless data compression algorithm, which USES a combination of the LZ77 algorithm and Huffman coding.

gzip压缩器基于deflate无损数据压缩算法，它使用LZ77算法和Huffman编码的组合。

The RAW data format provides pure data for high-resolution images, and uses lossless compression for more compact, yet uncompromised, data files.
