Data compression is the decrease of the number of bits which have to be stored or transmitted and this process is rather important in the internet hosting field due to the fact that data filed on hard drives is generally compressed so as to take less space. You'll find many different algorithms for compressing data and they have different effectiveness based upon the content. Many of them remove only the redundant bits, so no data can be lost, while others erase unnecessary bits, which leads to worse quality once your data is uncompressed. This method consumes a lot of processing time, which means that a web hosting server should be powerful enough so as to be able to compress and uncompress data instantly. An illustration how binary code may be compressed is by "remembering" that there are five consecutive 1s, for example, rather than storing all five 1s.

Data Compression in Cloud Hosting

The ZFS file system which is run on our cloud Internet hosting platform employs a compression algorithm called LZ4. The aforementioned is substantially faster and better than any other algorithm out there, especially for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data quicker than it is read from a hard drive, which improves the overall performance of Internet sites hosted on ZFS-based platforms. As the algorithm compresses data really well and it does that very fast, we are able to generate several backups of all the content stored in the cloud 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 very fast, the backup generation will not change the performance of the servers where your content will be stored.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting plans which we supply are created on a powerful cloud platform which runs on the ZFS file system. ZFS works with a compression algorithm called LZ4 that is greater than any other algorithm on the market in terms of speed and compression ratio when it comes to processing web content. This is valid particularly when data is uncompressed because LZ4 does that a lot faster than it would be to read uncompressed data from a hard disk and because of this, sites running on a platform where LZ4 is enabled will work at a higher speed. We can benefit from this feature despite of the fact that it requires quite a lot of CPU processing time because our platform uses a huge number of powerful servers working together and we do not create accounts on just a single machine like a lot of companies do. There's one more advantage of using LZ4 - given that it compresses data very well and does that very fast, we can also generate multiple daily backups of all accounts without influencing the performance of the servers and keep them for a month. That way, you will always be able to restore any content that you delete by accident.
