The term data compression refers to reducing the number of bits of information that has to be stored or transmitted. This can be achieved with or without the loss of data, which means that what will be deleted during the compression shall be either redundant data or unneeded one. When the data is uncompressed afterwards, in the first case the content and the quality will be the same, while in the second case the quality will be worse. You will find different compression algorithms that are better for various sort of info. Compressing and uncompressing data normally takes a lot of processing time, which means that the server performing the action must have plenty of resources to be able to process your info quick enough. One simple example how information can be compressed is to store just how many sequential positions should have 1 and just how many should have 0 inside the binary code as an alternative to storing the actual 1s and 0s.

Data Compression in Web Hosting

The compression algorithm which we employ on the cloud internet hosting platform where your new web hosting account will be created is called LZ4 and it's applied by the exceptional ZFS file system that powers the system. The algorithm is more advanced than the ones other file systems work with as its compression ratio is a lot higher and it processes data a lot faster. The speed is most noticeable when content is being uncompressed since this happens quicker than info can be read from a hard drive. As a result, LZ4 improves the performance of any site stored on a server that uses this algorithm. We take full advantage of LZ4 in one more way - its speed and compression ratio allow us to produce a couple of daily backups of the full content of all accounts and keep them for 30 days. Not only do these backup copies take less space, but in addition their generation won't slow the servers down like it can often happen with other file systems.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting plans which we supply are created on a powerful cloud platform which runs on the ZFS file system. ZFS uses a compression algorithm named LZ4 that outperforms any other algorithm available in terms of speed and compression ratio when it comes to processing web content. This is valid particularly when data is uncompressed because LZ4 does that quicker than it would be to read uncompressed data from a hard drive and for that reason, Internet sites running on a platform where LZ4 is enabled will work quicker. We can take advantage of this feature despite of the fact that it requires quite a large amount of CPU processing time because our platform uses numerous powerful servers working together and we never create accounts on a single machine like the vast majority of companies do. There's a further benefit of using LZ4 - considering the fact that it compresses data rather well and does that extremely fast, we can also generate several daily backups of all accounts without affecting the performance of the servers and keep them for 30 days. By doing this, you'll always be able to recover any content that you delete by mistake.
