The term data compression describes reducing the number of bits of info which should be saved or transmitted. You can do this with or without the loss of data, which means that what will be erased during the compression shall be either redundant data or unnecessary one. When the data is uncompressed subsequently, in the first case the content and its quality will be the same, while in the second case the quality shall be worse. You will find various compression algorithms that are better for different sort of info. Compressing and uncompressing data normally takes lots of processing time, which means that the server performing the action needs to have sufficient resources to be able to process the data fast enough. A simple example how information can be compressed is to store how many consecutive positions should have 1 and how many should have 0 inside the binary code rather than storing the actual 1s and 0s.

Data Compression in Web Hosting

The compression algorithm which we use on the cloud internet hosting platform where your new web hosting account shall be created is known as LZ4 and it's used by the cutting-edge ZFS file system that powers the platform. The algorithm is superior to the ones other file systems use since its compression ratio is much higher and it processes data significantly faster. The speed is most noticeable when content is being uncompressed as this happens quicker than information can be read from a hard disk drive. Consequently, LZ4 improves the performance of every Internet site located on a server that uses this algorithm. We use LZ4 in one more way - its speed and compression ratio make it possible for us to make a number of daily backups of the entire content of all accounts and store them for a month. Not only do these backup copies take less space, but also their generation does not slow the servers down like it often happens with various other file systems.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting plans which we provide are created on a powerful cloud hosting platform that runs on the ZFS file system. ZFS uses a compression algorithm called LZ4 that surpasses any other algorithm available in terms of speed and data compression ratio when it comes to processing web content. This is valid especially when data is uncompressed because LZ4 does that quicker than it would be to read uncompressed data from a hard drive and because of this, sites running on a platform where LZ4 is present will function at a higher speed. We can take full advantage of the feature regardless of the fact that it needs quite a large amount of CPU processing time because our platform uses a number of powerful servers working together and we don't create accounts on a single machine like the vast majority of companies do. There's one more advantage of using LZ4 - considering that it compresses data rather well and does that extremely fast, we can also make multiple daily backups of all accounts without influencing the performance of the servers and keep them for an entire month. By doing this, you will always be able to recover any content that you delete by accident.
