The term data compression identifies reducing the number of bits of info that should be stored or transmitted. This can be achieved with or without the loss of info, so what will be deleted during the compression can be either redundant data or unneeded one. When the data is uncompressed later on, in the first case the info and the quality will be the same, whereas in the second case the quality shall be worse. There are different compression algorithms which are more effective for various kind of information. Compressing and uncompressing data normally takes plenty of processing time, so the server carrying out the action should have ample resources in order to be able to process the data quick enough. An example how information can be compressed is to store just how many consecutive positions should have 1 and just how many should have 0 within the binary code rather than storing the actual 1s and 0s.

Data Compression in Cloud Hosting

The compression algorithm that we employ on the cloud web hosting platform where your new cloud hosting account shall be created is known as LZ4 and it's used by the advanced ZFS file system that powers the platform. The algorithm is greater than the ones other file systems employ as its compression ratio is a lot higher and it processes data considerably quicker. The speed is most noticeable when content is being uncompressed as this happens at a faster rate than info can be read from a hard disk. Because of this, LZ4 improves the performance of every Internet site stored on a server that uses the algorithm. We use LZ4 in an additional way - its speed and compression ratio allow us to produce multiple daily backup copies of the whole content of all accounts and store them for a month. Not only do these backup copies take less space, but their generation won't slow the servers down like it often happens with some other file systems.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting plans that we supply are created on a powerful cloud hosting platform that runs on the ZFS file system. ZFS employs a compression algorithm called LZ4 that is better than any other algorithm these days in terms of speed and compression ratio when it comes to processing website content. This is valid especially when data is uncompressed since LZ4 does that a lot faster than it would be to read uncompressed data from a hard disk and owing to this, sites running on a platform where LZ4 is enabled will function at a higher speed. We're able to benefit from the feature regardless of the fact that it needs quite a large amount of CPU processing time as our platform uses many powerful servers working together and we don't make accounts on just a single machine like the majority of companies do. There is another advantage of using LZ4 - considering that it compresses data really well and does that speedily, we can also generate several daily backups of all accounts without affecting the performance of the servers and keep them for a month. By doing this, you can always recover any content that you delete by mistake.
