Data compression is the reduction of the number of bits that should be stored or transmitted and the process is rather important in the internet hosting field due to the fact that information filed on HDDs is usually compressed so as to take less space. There're many different algorithms for compressing data and they offer different efficiency based on the content. Some of them remove just the redundant bits, so that no data can be lost, while others remove unneeded bits, which results in worse quality when the data is uncompressed. This method employs a lot of processing time, therefore a web hosting server needs to be powerful enough so as to be able to compress and uncompress data in real time. One example how binary code could be compressed is by "remembering" that there're five sequential 1s, for example, in contrast to storing all five 1s.

Data Compression in Website Hosting

The compression algorithm that we employ on the cloud hosting platform where your new website hosting account will be created is named LZ4 and it's applied by the state-of-the-art ZFS file system which powers the system. The algorithm is more advanced than the ones other file systems use because its compression ratio is a lot higher and it processes data significantly quicker. The speed is most noticeable when content is being uncompressed as this happens quicker than information can be read from a hard disk. Therefore, LZ4 improves the performance of any site located on a server which uses the algorithm. We take full advantage of LZ4 in one more way - its speed and compression ratio allow us to make a couple of daily backups of the whole content of all accounts and keep them for thirty days. Not only do our backup copies take less space, but also their generation does not slow the servers down like it often happens with many other file systems.
