The term data compression identifies lowering the number of bits of data which should be stored or transmitted. This can be done with or without losing data, so what will be removed throughout the compression shall be either redundant data or unnecessary one. When the data is uncompressed afterwards, in the first case the data and its quality will be identical, whereas in the second case the quality will be worse. You will find various compression algorithms which are better for various sort of info. Compressing and uncompressing data usually takes lots of processing time, which means that the server performing the action must have enough resources in order to be able to process the info quick enough. An example how information can be compressed is to store just how many sequential positions should have 1 and how many should have 0 in the binary code instead of storing the actual 1s and 0s.

Data Compression in Cloud Web Hosting

The compression algorithm used by the ZFS file system that runs on our cloud hosting platform is called LZ4. It can boost the performance of any Internet site hosted in a cloud web hosting account with us since not only does it compress data much better than algorithms employed by other file systems, but it uncompresses data at speeds that are higher than the HDD reading speeds. This can be done 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. One more advantage of LZ4 is that it allows us to generate backups a lot faster and on reduced disk space, so we will have several daily backups of your databases and files and their generation will not change the performance of the servers. In this way, we can always recover all of the content that you may have removed by accident.

Data Compression in Semi-dedicated Servers

In case you host your sites in a semi-dedicated server account with our firm, you can experience the advantages of LZ4 - the powerful compression algorithm employed by the ZFS file system which is behind our advanced cloud hosting platform. What separates LZ4 from all other algorithms out there is that it has a better compression ratio and it is much faster, 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 faster. The higher speed is at the expense of using plenty of CPU processing time, that's not an issue for our platform because it consists of multiple clusters working together. In combination with the improved performance, you'll also have multiple daily backup copies at your disposal, so you can recover any deleted content with just a couple of clicks. The backup copies are available for an entire month and we can afford to keep them because they need considerably less space compared to standard backups.
