Data compression is the compacting of info by reducing the number of bits that are stored or transmitted. This way, the compressed data will need much less disk space than the original one, so additional content might be stored on identical amount of space. There are many different compression algorithms which function in different ways and with many of them only the redundant bits are deleted, therefore once the information is uncompressed, there's no loss of quality. Others delete unneeded bits, but uncompressing the data afterwards will lead to lower quality compared to the original. Compressing and uncompressing content requires a huge amount of system resources, in particular CPU processing time, therefore each and every hosting platform which uses compression in real time should have adequate power to support this feature. An example how info can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" the number of consecutive 1s or 0s there should be instead of keeping the entire code.

Data Compression in Cloud Web Hosting

The ZFS file system which runs on our cloud hosting platform uses a compression algorithm called LZ4. The latter is substantially faster and better than any other algorithm you will find, particularly for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data quicker than it is read from a hard drive, which improves the performance of Internet sites hosted on ZFS-based platforms. Since the algorithm compresses data really well and it does that quickly, we can generate several backups of all the content kept in the cloud web hosting accounts on our servers on a daily basis. 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 web hosting 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 employs a compression algorithm called LZ4 that is superior to any other algorithm these days in terms of speed and data compression ratio when it comes to processing website content. This is valid particularly when data is uncompressed since LZ4 does that quicker than it would be to read uncompressed data from a hard disk and owing to this, Internet sites running on a platform where LZ4 is present will function at a higher speed. We can benefit from this feature despite of the fact that it needs quite a lot of CPU processing time because our platform uses a number of powerful servers working together and we never create accounts on a single machine like a lot of companies do. There is another benefit of using LZ4 - given that it compresses data very well and does that speedily, we can also generate multiple daily backups of all accounts without affecting the performance of the servers and keep them for a whole month. That way, you can always restore any content that you erase by accident.
