The term data compression identifies lowering the number of bits of information that should be stored or transmitted. You can do this with or without losing information, so what will be erased in the course of the compression can be either redundant data or unnecessary one. When the data is uncompressed afterwards, in the first case the content and its quality shall be identical, while in the second case the quality will be worse. You'll find various compression algorithms which are better for different kind of data. Compressing and uncompressing data in most cases takes lots of processing time, so the server executing the action must have plenty of resources in order to be able to process the info fast enough. One simple example how information can be compressed is to store just how many sequential positions should have 1 and how many should have 0 inside the binary code rather than storing the particular 1s and 0s.
Data Compression in Web Hosting
The compression algorithm used by the ZFS file system that runs on our cloud web hosting platform is known as LZ4. It can enhance the performance of any Internet site hosted in a web hosting account on our end since not only does it compress data more effectively than algorithms employed by various file systems, but also uncompresses data at speeds that are higher than the hard disk drive reading speeds. This is achieved by using a great deal 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. One more advantage of LZ4 is that it allows us to generate backups at a higher speed and on lower disk space, so we can have several daily backups of your files and databases and their generation won't influence the performance of the servers. This way, we can always restore the content that you could have erased by mistake.
Data Compression in Semi-dedicated Hosting
In case you host your sites in a semi-dedicated hosting account from our firm, you can experience the advantages of LZ4 - the powerful compression algorithm used by the ZFS file system that is behind our advanced cloud hosting platform. What separates LZ4 from all the other algorithms out there is that it has an improved compression ratio and it is considerably quicker, in particular with regard to uncompressing website content. It does that even faster than uncompressed data can be read from a hard disk drive, so your sites will perform better. The higher speed comes at the expense of using a considerable amount of CPU processing time, that is not a problem for our platform as it consists of a lot of clusters working together. Along with the improved performance, you will also have multiple daily backup copies at your disposal, so you could restore any deleted content with several clicks. The backup copies are available for a whole month and we can afford to store them because they need significantly less space compared to traditional backups.
