The term data compression refers to reducing the number of bits of information that should be saved or transmitted. You can do this with or without the loss of data, which means that what will be erased in the course of the compression can be either redundant data or unneeded one. When the data is uncompressed subsequently, in the first case the information and its quality will be identical, whereas in the second case the quality will be worse. There're different compression algorithms which are better for various kind of information. Compressing and uncompressing data in most cases takes plenty of processing time, therefore the server executing the action needs to have enough resources to be able to process your info quick enough. A 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 within the binary code rather than storing the actual 1s and 0s.

Data Compression in Website Hosting

The compression algorithm employed by the ZFS file system which runs on our cloud web hosting platform is named LZ4. It can enhance the performance of any site hosted in a website hosting account with us since not only does it compress data significantly better than algorithms used by various other file systems, but also uncompresses data at speeds which are higher than the hard drive reading speeds. This is achieved by using a great deal of CPU processing time, which is not a problem for our platform considering the fact that it uses clusters of powerful servers working together. One more advantage of LZ4 is that it enables us to create backups much more rapidly and on lower disk space, so we will have several daily backups of your files and databases and their generation will not affect the performance of the servers. This way, we could always recover any kind of content that you may have erased by accident.

Data Compression in Semi-dedicated Servers

In case you host your sites in a semi-dedicated server account from our company, you'll be able to experience the advantages of LZ4 - the powerful compression algorithm employed by the ZFS file system that's behind our advanced cloud hosting platform. What separates LZ4 from all of the other algorithms out there is that it has a better compression ratio and it is much quicker, especially when it comes to uncompressing website content. It does that even faster than uncompressed data can be read from a hard drive, so your websites will perform better. The higher speed is at the expense of using a considerable amount of CPU processing time, that is not an issue for our platform because it consists of a lot of clusters working together. Together with the superior performance, you will also have multiple daily backup copies at your disposal, so you'll be able to recover any deleted content with a few clicks. The backups are available for an entire month and we can afford to store them because they take significantly less space than ordinary backups.
