The term data compression means decreasing the number of bits of data that needs to be saved or transmitted. This can be done with or without losing information, so what will be removed 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 info and the quality will be identical, while in the second case the quality shall be worse. You will find different compression algorithms which are more effective for various kind of data. Compressing and uncompressing data usually takes lots of processing time, which means that the server performing the action needs to have ample resources in order to be able to process your info quick enough. A simple example how information can be compressed is to store how many consecutive positions should have 1 and just how many should have 0 in the binary code rather than storing the particular 1s and 0s.

Data Compression in Cloud Hosting

The cloud web hosting platform where your cloud hosting account will be generated uses the outstanding ZFS file system. The LZ4 compression method that the aforementioned uses is better in numerous aspects, and not only does it compress info better than any compression method that some other file systems use, but it is also quicker. The benefits will be significant particularly on compressible content like website files. Despite the fact that it may sound irrational, uncompressing data with LZ4 is quicker than reading uncompressed data from a hard disk drive, so the performance of each site hosted on our servers shall be upgraded. The better and quicker compression rates also allow us to make multiple daily backups of the whole content in each hosting account, so if you delete something by accident, the last backup that we have will not be more than several hours old. This is possible as the backups take much less space and their generation is quick enough, so as to not affect the performance of our servers.

Data Compression in Semi-dedicated Servers

Your semi-dedicated server account shall be created on a cloud platform that runs using the state-of-the-art ZFS file system. The aforementioned uses a compression algorithm called LZ4, that is significantly better than alternative algorithms regarding compression ratio and speed. The gain is significant particularly when data is being uncompressed and not only is LZ4 a lot faster than other algorithms, but it is also faster in uncompressing data than a system is in reading from a hard disk. This is why websites running on a platform which uses LZ4 compression perform better since the algorithm is most efficient when it processes compressible data i.e. website content. Another advantage of using LZ4 is that the backups of the semi-dedicated accounts that we keep need significantly less space and they are generated a lot faster, which allows us to keep multiple daily backups of your files and databases.
