The term data compression identifies reducing the number of bits of information which needs to be saved or transmitted. This can be done with or without losing information, which means that what will be erased during the compression will be either redundant data or unneeded one. When the data is uncompressed afterwards, in the first case the info and its quality will be identical, while in the second case the quality shall be worse. You'll find various compression algorithms that are more effective for various type of info. Compressing and uncompressing data normally takes lots of processing time, therefore the server executing the action needs to have enough resources in order to be able to process the info quick enough. An example how information can be compressed is to store just how many consecutive positions should have 1 and just how many should have 0 inside the binary code instead of storing the actual 1s and 0s.

Data Compression in Shared Web Hosting

The ZFS file system that operates on our cloud web hosting platform employs a compression algorithm named LZ4. The aforementioned is substantially faster and better than any other algorithm you'll find, especially for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data quicker than it is read from a hard disk drive, which improves the performance of sites hosted on ZFS-based platforms. As the algorithm compresses data really well and it does that quickly, we are able to generate several backups of all the content stored in the shared web hosting accounts on our servers every day. Both your content and its backups will need less space and since both ZFS and LZ4 work very quickly, the backup generation will not affect the performance of the hosting servers where your content will be kept.

Data Compression in Semi-dedicated Servers

If you host your sites in a semi-dedicated server account from our company, you will be able to experience the advantages of LZ4 - the powerful compression algorithm used by the ZFS file system that's behind our advanced cloud Internet hosting platform. What separates LZ4 from all other algorithms out there is that it has a better compression ratio and it is much faster, in particular with regard to uncompressing website content. It does that even faster than uncompressed information can be read from a hard disk drive, so your websites will perform better. The higher speed comes at the expense of using lots of CPU processing time, that is not a problem for our platform as it consists of multiple clusters working together. In combination with the better performance, you'll have multiple daily backups at your disposal, so you can restore any deleted content with several clicks. The backups are available for an entire month and we can afford to keep them as they take significantly less space than standard backups.
