The term data compression means decreasing the number of bits of data that needs to be saved or transmitted. This can be done with or without the loss of info, so what will be erased in the course of the compression shall be either redundant data or unnecessary one. When the data is uncompressed later on, in the first case the information and its quality will be identical, while in the second case the quality shall be worse. You'll find various compression algorithms that are more effective for different kind of information. Compressing and uncompressing data generally takes plenty of processing time, therefore the server performing the action needs to have adequate resources in order to be able to process your info quick enough. One simple example how information can be compressed is to store just how many consecutive positions should have 1 and just how many should have 0 inside the binary code instead of storing the particular 1s and 0s.

Data Compression in Web Hosting

The compression algorithm used by the ZFS file system which runs on our cloud internet hosting platform is called LZ4. It can supercharge the performance of any Internet site hosted in a web hosting account on our end because not only does it compress info much better than algorithms used by various file systems, but it uncompresses data at speeds that are higher than the hard disk reading speeds. This is achieved by using a great deal of CPU processing time, which is not a problem for our platform because it uses clusters of powerful servers working together. A further advantage of LZ4 is that it allows us to create backups more speedily and on lower disk space, so we will have several daily backups of your files and databases and their generation won't affect the performance of the servers. In this way, we can always recover all of the content that you could have erased by mistake.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting plans that we supply are created on a powerful cloud platform that 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 compression ratio when it comes to processing website content. This is valid especially when data is uncompressed because LZ4 does that a lot faster than it would be to read uncompressed data from a hard disk and owing to this, websites running on a platform where LZ4 is present will work quicker. We can take advantage of the feature although it needs quite a lot 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 many companies do. There's an additional advantage of using LZ4 - given that it compresses data rather well and does that extremely fast, we can also generate multiple daily backups of all accounts without affecting the performance of the servers and keep them for an entire month. That way, you will always be able to recover any content that you delete by mistake.
