Data compression is the reduction of the number of bits which have to be saved or transmitted and the process is quite important in the internet hosting field as info filed on hard disk drives is usually compressed so as to take less space. You will find different algorithms for compressing info and they offer different effectiveness based on the content. A lot of them remove just the redundant bits, so that no data will be lost, while others remove unneeded bits, which leads to worse quality once your data is uncompressed. The method uses a lot of processing time, therefore a hosting server has to be powerful enough in order to be able to compress and uncompress data in real time. An instance 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 Web Hosting

The compression algorithm that we use on the cloud web hosting platform where your new web hosting account will be created is named LZ4 and it's used by the state-of-the-art ZFS file system which powers the platform. The algorithm is better than the ones other file systems use as its compression ratio is higher and it processes data significantly quicker. The speed is most noticeable when content is being uncompressed as this happens faster than data can be read from a hdd. For that reason, LZ4 improves the performance of each and every site stored on a server that uses this algorithm. We take full advantage of LZ4 in an additional way - its speed and compression ratio let us generate multiple daily backups of the entire content of all accounts and store them for one month. Not only do the backups take less space, but in addition their generation doesn't slow the servers down like it can often happen with various other file systems.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting plans that we supply are created on a powerful cloud platform which runs on the ZFS file system. ZFS works with a compression algorithm called LZ4 that is greater than any other algorithm available on the market in terms of speed and data compression ratio when it comes to processing website content. This is valid especially when data is uncompressed as LZ4 does that more rapidly than it would be to read uncompressed data from a hard disk drive and as a result, websites running on a platform where LZ4 is present will function faster. We can benefit from this feature although it requires quite a large amount of CPU processing time because our platform uses a large number of powerful servers working together and we do not make accounts on just a single machine like a lot of companies do. There is one more advantage of using LZ4 - given that it compresses data rather well and does that extremely fast, we can also make multiple daily backup copies of all accounts without influencing the performance of the servers and keep them for a month. In this way, you will always be able to restore any content that you delete by mistake.
