The term data compression describes lowering the number of bits of info which has to be saved or transmitted. You can do this with or without the loss of data, which means that what will be removed during the compression will be either redundant data or unnecessary one. When the data is uncompressed subsequently, in the first case the information and its quality shall be identical, whereas in the second case the quality will be worse. You will find various compression algorithms which are better for various sort of information. Compressing and uncompressing data frequently takes lots of processing time, which means that the server executing the action needs to have sufficient resources to be able to process your data quick enough. An example how information can be compressed is to store how many consecutive positions should have 1 and just how many should have 0 in the binary code instead of storing the particular 1s and 0s.
Data Compression in Hosting
The compression algorithm that we use on the cloud web hosting platform where your new hosting account shall be created is known as LZ4 and it is used by the exceptional ZFS file system which powers the system. The algorithm is better than the ones other file systems work with as its compression ratio is much higher and it processes data significantly quicker. The speed is most noticeable when content is being uncompressed since this happens more quickly than data can be read from a hard drive. As a result, LZ4 improves the performance of every website located on a server which uses this particular algorithm. We take advantage of LZ4 in an additional way - its speed and compression ratio make it possible for us to generate multiple daily backup copies of the whole content of all accounts and store them for 30 days. Not only do the backups take less space, but in addition their generation will not slow the servers down like it often happens with alternative file systems.
Data Compression in Semi-dedicated Hosting
The semi-dedicated hosting plans which we offer are created on a powerful cloud hosting platform which runs on the ZFS file system. ZFS employs a compression algorithm called LZ4 that is greater than any other algorithm available in terms of speed and data compression ratio when it comes to processing web content. This is valid particularly when data is uncompressed as LZ4 does that quicker 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 faster. We are able to take advantage of the feature despite of the fact that it needs quite a large amount of CPU processing time because our platform uses a huge number of powerful servers working together and we do not create accounts on a single machine like a lot of companies do. There's a further benefit of using LZ4 - since it compresses data very well and does that speedily, we can also make several daily backups of all accounts without affecting the performance of the servers and keep them for an entire month. In this way, you will always be able to restore any content that you delete by accident.
