Data compression is the decrease of the number of bits which have to be stored or transmitted and the process is rather important in the internet hosting field since info located on hard disk drives is often compressed in order to take less space. You can find many different algorithms for compressing info and they offer different efficiency based on the content. Many of them remove only the redundant bits, so no data will be lost, while others remove unnecessary bits, which results in worse quality when the data is uncompressed. This method uses plenty of processing time, which means that a hosting server needs to be powerful enough to be able to compress and uncompress data immediately. An illustration how binary code can be compressed is by "remembering" that there're five sequential 1s, for example, as an alternative to storing all five 1s.

Data Compression in Shared Web Hosting

The ZFS file system which is run on our cloud web hosting platform uses a compression algorithm called LZ4. The latter is significantly faster and better than any other algorithm on the market, particularly for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data quicker than it is read from a hard disk, which improves the performance of sites hosted on ZFS-based platforms. Due to the fact that the algorithm compresses data quite well and it does that quickly, we can generate several backup copies of all the content kept in the shared web hosting accounts on our servers every day. Both your content and its backups will need reduced space and since both ZFS and LZ4 work extremely fast, the backup generation will not change the performance of the hosting servers where your content will be stored.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting plans that we offer are created on a powerful cloud hosting platform which runs on the ZFS file system. ZFS uses a compression algorithm named LZ4 that surpasses any other algorithm available in terms of speed and compression ratio when it comes to processing web content. This is valid especially when data is uncompressed as LZ4 does that quicker than it would be to read uncompressed data from a hard disk and as a result, Internet sites running on a platform where LZ4 is present will work quicker. We can benefit from the feature although it requires quite a large amount of CPU processing time because our platform uses a large number of powerful servers working together and we do not create accounts on a single machine like the majority of companies do. There's another reward of using LZ4 - given that it compresses data very well and does that extremely fast, we can also generate multiple daily backup copies of all accounts without affecting the performance of the servers and keep them for an entire month. By doing this, you will always be able to recover any content that you erase by accident.
