The term data compression refers to lowering the number of bits of data which should be stored or transmitted. This can be done with or without the loss of info, which means that what will be erased in the course of the compression can be either redundant data or unnecessary one. When the data is uncompressed subsequently, in the first case the information and its quality shall be identical, while in the second case the quality shall be worse. You can find various compression algorithms which are more efficient for different sort of information. Compressing and uncompressing data usually takes a lot of processing time, so the server carrying out the action needs to have ample resources in order to be able to process your data quick enough. A simple example how information can be compressed is to store how many consecutive positions should have 1 and how many should have 0 within the binary code as an alternative to storing the actual 1s and 0s.

Data Compression in Semi-dedicated Hosting

If you host your websites in a semi-dedicated hosting account with our company, you can experience the advantages of LZ4 - the powerful compression algorithm used by the ZFS file system which is behind our advanced cloud web hosting platform. What distinguishes LZ4 from all of the other algorithms out there is that it has a better compression ratio and it is much quicker, particularly when it comes to uncompressing website content. It does that even quicker than uncompressed information can be read from a hard drive, so your sites will perform faster. The higher speed is at the expense of using a lot of CPU processing time, which is not a problem for our platform since it consists of a lot of clusters working together. In combination with the better performance, you'll also have multiple daily backup copies at your disposal, so you will be able to restore any deleted content with a few clicks. The backup copies are available for an entire month and we can afford to keep them since they need considerably less space than standard backups.
