The term data compression refers to reducing the number of bits of data which has to be saved or transmitted. This can be done with or without losing info, so what will be removed in the course of the compression shall be either redundant data or unnecessary one. When the data is uncompressed subsequently, in the first case the data and the quality shall be the same, whereas in the second case the quality will be worse. You'll find various compression algorithms that are more effective for various type of info. Compressing and uncompressing data often takes a lot of processing time, so the server executing the action needs to have enough resources to be able to process the data quick enough. One simple example how information can be compressed is to store just how many consecutive positions should have 1 and how many should have 0 inside the binary code rather than storing the actual 1s and 0s.

Data Compression in Shared Web Hosting

The cloud web hosting platform where your shared web hosting account will be created employs the advanced ZFS file system. The LZ4 compression method which the latter uses is better in a number of aspects, and not only does it compress data better than any compression method which a number of other file systems use, but it's also quicker. The gains may be significant in particular on compressible content such as website files. Although it could sound illogical, uncompressing data with LZ4 is faster than reading uncompressed data from a hard disk, so the performance of each and every site hosted on our servers will be enhanced. The better and faster compression rates also make it possible for us to produce multiple daily backups of the entire content in each hosting account, so in the event you delete anything by accident, the last back-up copy that we have will not be more than a few hours old. This is possible as the backups take considerably less space and their generation is quick enough, so as to not change the performance of the servers.
