Data compression is the reduction of the number of bits that need to be stored or transmitted and the process is quite important in the internet hosting field due to the fact that data located on hard disk drives is usually compressed in order to take less space. There are different algorithms for compressing info and they offer different efficiency based on the content. Some of them remove only the redundant bits, so that no data will be lost, while others delete unnecessary bits, which results in worse quality when the data is uncompressed. This process employs plenty of processing time, therefore an internet hosting server should be powerful enough to be able to compress and uncompress data immediately. An instance how binary code could be compressed is by "remembering" that there're five consecutive 1s, for example, in contrast to storing all five 1s.
Data Compression in Shared Web Hosting
The ZFS file system which runs on our cloud web hosting platform uses a compression algorithm named LZ4. The aforementioned is considerably faster and better than any other algorithm out there, especially for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data faster than it is read from a hard disk, which improves the overall performance of Internet sites hosted on ZFS-based platforms. Because the algorithm compresses data really well and it does that very quickly, we can generate several backups of all the content stored in the shared web hosting accounts on our servers on a daily basis. Both your content and its backups will require less space and since both ZFS and LZ4 work extremely fast, the backup generation will not influence the performance of the servers where your content will be stored.
Data Compression in Semi-dedicated Hosting
In case you host your sites in a semi-dedicated hosting account with our company, you'll be able to experience the advantages of LZ4 - the powerful compression algorithm used by the ZFS file system which is behind our advanced cloud hosting platform. What separates LZ4 from all of the other algorithms out there is that it has a better compression ratio and it is much quicker, particularly when it comes to uncompressing web content. It does that even faster than uncompressed data can be read from a hard disk drive, so your Internet sites will perform faster. The higher speed is at the expense of using plenty of CPU processing time, that's not an issue for our platform as it consists of a lot of clusters working together. In combination with the better performance, you'll also have multiple daily backup copies at your disposal, so you'll be able to restore any deleted content with a few clicks. The backup copies are available for a whole month and we can afford to keep them as they need a lot less space compared to conventional backups.
