The term data compression means decreasing the number of bits of data which needs to be stored or transmitted. This can be achieved with or without the loss of info, so what will be removed in the course of the compression will be either redundant data or unnecessary one. When the data is uncompressed later on, in the first case the info and the quality shall be the same, while in the second case the quality will be worse. You'll find various compression algorithms which are better for various sort of information. Compressing and uncompressing data frequently takes lots of processing time, therefore the server executing the action should have ample resources to be able to process your info fast enough. A simple example how information can be compressed is to store how many sequential positions should have 1 and just how many should have 0 within the binary code instead of storing the actual 1s and 0s.

Data Compression in Shared Web Hosting

The ZFS file system that runs on our cloud hosting platform employs a compression algorithm identified as LZ4. The aforementioned is significantly faster and better than any other algorithm out there, particularly for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data quicker than it is read from a hard disk, which improves the performance of Internet sites hosted on ZFS-based platforms. Due to the fact that the algorithm compresses data very well and it does that quickly, we are able to generate several backup copies of all the content kept in the shared web 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 affect the performance of the web hosting servers where your content will be stored.

Data Compression in Semi-dedicated Servers

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