The term data compression describes reducing the number of bits of information that should be saved or transmitted. This can be achieved with or without losing data, which means that what will be erased during the compression shall be either redundant data or unneeded one. When the data is uncompressed afterwards, in the first case the data and its quality shall be identical, while in the second case the quality will be worse. You can find various compression algorithms that are better for different sort of info. Compressing and uncompressing data usually takes a lot of processing time, therefore the server executing the action needs to have plenty of resources to be able to process your info fast enough. A simple example how information can be compressed is to store how many sequential positions should have 1 and just how many should have 0 within the binary code as an alternative to storing the particular 1s and 0s.

Data Compression in Shared Web Hosting

The compression algorithm employed by the ZFS file system which runs on our cloud internet hosting platform is named LZ4. It can enhance the performance of any site hosted in a shared web hosting account with us since not only does it compress info more efficiently than algorithms employed by various file systems, but it uncompresses data at speeds that are higher than the HDD reading speeds. This can be done by using a lot of CPU processing time, which is not a problem for our platform owing to the fact that it uses clusters of powerful servers working together. A further advantage of LZ4 is that it allows us to make backup copies faster and on reduced disk space, so we will have a couple of daily backups of your databases and files and their generation will not influence the performance of the servers. That way, we can always restore any content that you may have erased by mistake.

Data Compression in Semi-dedicated Servers

The semi-dedicated server plans that we supply 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 you can find in terms of speed and data compression ratio when it comes to processing web content. This is valid particularly when data is uncompressed since LZ4 does that faster than it would be to read uncompressed data from a hard disk and because of this, Internet sites running on a platform where LZ4 is present will work at a higher speed. We are able to benefit from the feature regardless of the fact that it requires quite a lot of CPU processing time as our platform uses a wide range of powerful servers working together and we do not make accounts on just a single machine like a lot of companies do. There's another benefit of using LZ4 - since 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 30 days. In this way, you will always be able to restore any content that you erase by mistake.
