Data compression is the lowering of the number of bits which have to be saved or transmitted and this particular process is quite important in the web hosting field as info stored on hard drives is typically compressed so as to take less space. You can find different algorithms for compressing information and they provide different effectiveness based on the content. A number of them remove only the redundant bits, so that no data can be lost, while others erase unneeded bits, which results in worse quality when your data is uncompressed. This method uses a lot of processing time, so an internet hosting server has to be powerful enough in order to be able to compress and uncompress data right away. An instance how binary code can be compressed is by "remembering" that there are five consecutive 1s, for example, rather than storing all five 1s.
Data Compression in Shared Website Hosting
The cloud internet hosting platform where your shared website hosting account is generated works by using the advanced ZFS file system. The LZ4 compression method that the aforementioned uses is greater in a number of aspects, and not only does it compress data better than any compression method that similar file systems use, but it is also a lot quicker. The gains are significant especially on compressible content like website files. Although it could sound unreasonable, uncompressing data with LZ4 is quicker than reading uncompressed data from a hard drive, so the performance of any site hosted on our servers shall be boosted. The better and faster compression rates also make it possible for us to produce numerous daily backups of the full content in each web hosting account, so in the event you delete something by mistake, the last backup 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, to not change the performance of our servers.
Data Compression in Semi-dedicated Hosting
The semi-dedicated hosting plans that we supply are created on a powerful cloud platform which runs on the ZFS file system. ZFS uses a compression algorithm called LZ4 that is superior to any other algorithm you can find in terms of speed and data compression ratio when it comes to processing website content. This is valid especially when data is uncompressed as LZ4 does that more rapidly than it would be to read uncompressed data from a hard drive and because of this, Internet sites running on a platform where LZ4 is present will work at a higher speed. We're able to take advantage of the feature although it requires quite a large amount of CPU processing time because our platform uses a number of powerful servers working together and we never make accounts on just a single machine like the vast majority of companies do. There is an additional reward of using LZ4 - considering the fact that it compresses data rather well and does that very quickly, we can also generate multiple daily backups of all accounts without influencing the performance of the servers and keep them for an entire month. This way, you will always be able to bring back any content that you erase by mistake.
