Data compression is the decrease of the number of bits which need to be stored or transmitted and this particular process is quite important in the web hosting field as information filed on hard disk drives is usually compressed to take less space. There're many different algorithms for compressing information and they provide different effectiveness based upon the content. A number of them remove only the redundant bits, so that no data will be lost, while others erase unnecessary bits, which results in worse quality once the particular data is uncompressed. The process consumes plenty of processing time, so an internet hosting server should be powerful enough so as to be able to compress and uncompress data right away. An illustration how binary code could be compressed is by "remembering" that there are five sequential 1s, for example, in contrast to storing all five 1s.

Data Compression in Website Hosting

The compression algorithm that we work with on the cloud internet hosting platform where your new website hosting account shall be created is called LZ4 and it's used by the exceptional ZFS file system that powers the system. The algorithm is a lot better than the ones other file systems work with because its compression ratio is much higher and it processes data a lot quicker. The speed is most noticeable when content is being uncompressed since this happens faster than information can be read from a hard drive. Therefore, LZ4 improves the performance of each and every site located on a server that uses the algorithm. We take advantage of LZ4 in an additional way - its speed and compression ratio let us produce multiple daily backup copies of the full content of all accounts and keep them for thirty days. Not only do our backup copies take less space, but also their generation won't slow the servers down like it can often happen with many other file systems.
