Data compression is the compacting of data by lowering the number of bits that are stored or transmitted. In this way, the compressed data will need considerably less disk space than the original one, so additional content could be stored using the same amount of space. You can find different compression algorithms that function in different ways and with a number of them just the redundant bits are removed, so once the information is uncompressed, there's no decrease in quality. Others erase unneeded bits, but uncompressing the data subsequently will lead to reduced quality in comparison with the original. Compressing and uncompressing content takes a large amount of system resources, and in particular CPU processing time, therefore every hosting platform that employs compression in real time needs to have adequate power to support that feature. An example how information can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" what number of sequential 1s or 0s there should be instead of saving the whole code.

Data Compression in Web Hosting

The compression algorithm that we work with on the cloud web hosting platform where your new web hosting account will be created is called LZ4 and it's applied by the revolutionary ZFS file system which powers the platform. The algorithm is superior to the ones other file systems work with since its compression ratio is much higher and it processes data significantly quicker. The speed is most noticeable when content is being uncompressed as this happens at a faster rate than information can be read from a hdd. Because of this, LZ4 improves the performance of every website hosted on a server that uses this particular algorithm. We use LZ4 in an additional way - its speed and compression ratio let us generate a couple of daily backups of the entire content of all accounts and store them for a month. Not only do our backups take less space, but their generation does not slow the servers down like it can often happen with many other file systems.

Data Compression in Semi-dedicated Servers

The semi-dedicated server plans which we supply are created on a powerful cloud platform that runs on the ZFS file system. ZFS works with a compression algorithm named LZ4 that is greater than any other algorithm you will find in terms of speed and data compression ratio when it comes to processing website content. This is valid especially when data is uncompressed since LZ4 does that more quickly than it would be to read uncompressed data from a hard disk drive and as a result, sites running on a platform where LZ4 is present will work at a higher speed. We are able to take full advantage of the feature regardless of the fact that it needs quite a great deal of CPU processing time because our platform uses a number of powerful servers working together and we don't make accounts on a single machine like the majority of companies do. There's one more reward of using LZ4 - considering the fact that it compresses data very well and does that very fast, we can also generate multiple daily backups of all accounts without influencing the performance of the servers and keep them for 30 days. This way, you'll always be able to bring back any content that you erase by mistake.
