Data compression is the lowering of the number of bits which have to be saved or transmitted and this process is rather important in the internet hosting field since info filed on hard disks is often compressed to take less space. You will find various algorithms for compressing information and they provide different effectiveness based on the content. Some of them remove only the redundant bits, so that no data can be lost, while others erase unnecessary bits, which leads to worse quality when the data is uncompressed. The method employs a lot of processing time, therefore a web hosting server needs to be powerful enough in order to be able to compress and uncompress data immediately. An illustration how binary code could be compressed is by "remembering" that there're five consecutive 1s, for example, as an alternative to storing all five 1s.
Data Compression in Web Hosting
The cloud web hosting platform where your web hosting account will be created uses the outstanding ZFS file system. The LZ4 compression method which the aforementioned uses is superior in numerous aspects, and not only does it compress information better than any compression method that some other file systems use, but it is also much quicker. The gains are significant in particular on compressible content which includes website files. Despite the fact that it may sound unreasonable, uncompressing data with LZ4 is faster than reading uncompressed info from a hard disk, so the performance of each site hosted on our servers will be upgraded. The better and faster compression rates also allow us to produce numerous daily backups of the full content in every single hosting account, so should you delete something by accident, the last back-up copy which we have will not be more than a few hours old. This can be done as the backups take significantly less space and their generation is fast enough, so as to not affect the performance of the servers.
Data Compression in Semi-dedicated Servers
Your semi-dedicated server account will be created on a cloud platform that is run on the state-of-the-art ZFS file system. The latter uses a compression algorithm called LZ4, that's far better than various other algorithms regarding compression ratio and speed. The gain is visible especially when data is being uncompressed and not only is LZ4 quicker than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a HDD. This is why sites running on a platform which employs LZ4 compression perform faster since the algorithm is most efficient when it processes compressible data i.e. site content. A further advantage of using LZ4 is that the backups of the semi-dedicated accounts which we keep take much less space and are generated quicker, which allows us to have multiple daily backups of all your files and databases.
