Data compression is the reduction of the number of bits which need to be saved or transmitted and this particular process is rather important in the internet hosting field because info kept on HDDs is generally compressed to take less space. You can find many different algorithms for compressing data and they offer different effectiveness based on the content. Many of them remove just the redundant bits, so that no data will be lost, while others erase unnecessary bits, which results in worse quality when your data is uncompressed. The process requires a lot of processing time, so a hosting server has to be powerful enough in order to be able to compress and uncompress data instantly. An example how binary code may be compressed is by "remembering" that there're five sequential 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 is created employs the impressive ZFS file system. The LZ4 compression method that the aforementioned uses is better in various aspects, and not only does it compress info better than any compression method which other file systems use, but it's also a lot quicker. The gains can be significant especially on compressible content such as website files. Even though it could sound irrational, uncompressing data with LZ4 is faster than reading uncompressed data from a hard disk drive, so the performance of each and every site hosted on our servers shall be better. The better and faster compression rates also make it possible for us to produce a number of daily backups of the full content in every single Internet hosting account, so in the event you delete something by mistake, the last back-up copy that we have will not be more than a few hours old. This is possible as the backups take a lot less space and their generation is quick enough, to not influence the performance of our 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 known as LZ4, which is much better than all the 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 sites running on a platform that uses LZ4 compression perform faster since the algorithm is most efficient when it processes compressible data i.e. web content. One more advantage of using LZ4 is that the backup copies of the semi-dedicated accounts which we keep require a lot less space and they're generated quicker, which allows us to store a number of daily backups of all your files and databases.
