The term data compression describes lowering the number of bits of information which has to be stored or transmitted. This can be done with or without the loss of info, so what will be deleted 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 info and its quality shall be identical, while in the second case the quality will be worse. You will find different compression algorithms which are better for different kind of data. Compressing and uncompressing data in most cases takes plenty of processing time, so the server executing the action must have plenty of resources in order to be able to process your info fast 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 within the binary code instead of storing the particular 1s and 0s.

Data Compression in Web Hosting

The cloud web hosting platform where your web hosting account is generated employs the cutting-edge ZFS file system. The LZ4 compression method that the aforementioned employs is better in numerous aspects, and not only does it compress information better than any compression method which many other file systems use, but it is also a lot quicker. The gains can be significant particularly on compressible content like website files. Despite the fact that it could sound illogical, uncompressing data with LZ4 is faster than reading uncompressed info from a hard disk drive, so the performance of any Internet site hosted on our servers will be upgraded. The better and faster compression rates also allow us to generate numerous daily backups of the full content in every single web hosting account, so should you delete anything by mistake, the last back-up copy that we have won't be more than a couple of hours old. This is possible because the backups take a lot less space and their generation is fast enough, to not influence the performance of our servers.

Data Compression in Semi-dedicated Servers

Your semi-dedicated server account shall be created on a cloud platform that is run on the advanced ZFS file system. The aforementioned uses a compression algorithm known as LZ4, which is a lot better than other algorithms when it comes to compression ratio and speed. The gain is visible especially when data is being uncompressed and not only is LZ4 a lot faster than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a hard disk drive. This is the reason why websites running on a platform that uses LZ4 compression perform better because the algorithm is most efficient when it processes compressible data i.e. web content. An additional advantage of using LZ4 is that the backup copies of the semi-dedicated accounts which we keep take much less space and they are generated faster, which allows us to have several daily backups of all your files and databases.
