Data compression is the reduction of the number of bits which have to be stored or transmitted and this particular process is rather important in the web hosting field since data kept on hard disk drives is usually compressed in order to take less space. You will find different algorithms for compressing data and they have different effectiveness depending on the content. A lot of them remove just the redundant bits, so no data can be lost, while others delete unneeded bits, which leads to worse quality once the data is uncompressed. This method uses plenty of processing time, so a web hosting server has to be powerful enough to be able to compress and uncompress data instantly. One example how binary code could be compressed is by "remembering" that there are five sequential 1s, for example, in contrast to storing all five 1s.

Data Compression in Hosting

The ZFS file system that is run on our cloud hosting platform employs a compression algorithm named LZ4. The aforementioned is considerably faster and better than every other algorithm on the market, particularly for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data faster than it is read from a hard drive, which improves the overall performance of Internet sites hosted on ZFS-based platforms. Due to the fact that the algorithm compresses data very well and it does that very fast, we're able to generate several backups of all the content kept in the hosting accounts on our servers daily. Both your content and its backups will take reduced space and since both ZFS and LZ4 work very quickly, the backup generation will not influence the performance of the hosting servers where your content will be kept.

Data Compression in Semi-dedicated Servers

The semi-dedicated server plans that we supply are created on a powerful cloud hosting platform that runs on the ZFS file system. ZFS employs a compression algorithm known as LZ4 that surpasses any other algorithm on the market in terms of speed and data compression ratio when it comes to processing web content. This is valid especially when data is uncompressed since LZ4 does that faster than it would be to read uncompressed data from a hard disk drive and owing to this, websites running on a platform where LZ4 is enabled will function at a higher speed. We can benefit from this feature although it needs quite a lot of CPU processing time because our platform uses a large 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 another reward of using LZ4 - since it compresses data really well and does that speedily, we can also make multiple daily backups of all accounts without affecting the performance of the servers and keep them for an entire month. This way, you can always bring back any content that you erase by accident.
