Data compression is the decrease of the number of bits which should be saved or transmitted and this particular process is really important in the web hosting field as info filed on HDDs is usually compressed to take less space. You can find many different algorithms for compressing info and they provide different effectiveness based upon the content. A number of them remove only the redundant bits, so that no data can be lost, while others erase unnecessary bits, which leads to worse quality when the data is uncompressed. The method consumes a lot of processing time, so a web hosting server needs to be powerful enough so as to be able to compress and uncompress data right away. One example how binary code can be compressed is by "remembering" that there're five consecutive 1s, for example, as an alternative to storing all five 1s.

Data Compression in Hosting

The compression algorithm that we work with on the cloud hosting platform where your new hosting account shall be created is named LZ4 and it is used by the state-of-the-art ZFS file system which powers the system. The algorithm is better than the ones other file systems use because its compression ratio is higher and it processes data a lot quicker. The speed is most noticeable when content is being uncompressed as this happens quicker than info can be read from a hard drive. Consequently, LZ4 improves the performance of each and every Internet site hosted on a server which uses this particular algorithm. We take full advantage of LZ4 in an additional way - its speed and compression ratio make it possible for us to make several daily backups of the full content of all accounts and keep them for one month. Not only do these backups take less space, but in addition their generation does not slow the servers down like it often happens with other file systems.
