The term data compression means lowering the number of bits of information that needs to be stored or transmitted. This can be done with or without losing information, so what will be removed throughout the compression shall be either redundant data or unneeded one. When the data is uncompressed subsequently, in the first case the info and the quality will be identical, whereas in the second case the quality will be worse. You will find different compression algorithms which are more efficient for different kind of info. Compressing and uncompressing data generally takes plenty of processing time, which means that the server performing the action must have enough resources in order to be able to process your data quick enough. An example how information can be compressed is to store just how many sequential positions should have 1 and how many should have 0 inside the binary code rather than storing the particular 1s and 0s.
Data Compression in Cloud Web Hosting
The cloud web hosting platform where your cloud web hosting account shall be generated uses the cutting-edge ZFS file system. The LZ4 compression method that the aforementioned uses is better in various aspects, and not only does it compress information better than any compression method which many other file systems use, but it is also considerably quicker. The benefits can be significant especially on compressible content such as website files. While it could sound irrational, uncompressing data with LZ4 is faster than reading uncompressed info from a hard disk, so the performance of each and every site hosted on our servers shall be enhanced. The better and faster compression rates also make it possible for us to generate numerous daily backups of the whole content in each hosting account, so if you delete anything by accident, the last back-up copy that we have won't be more than several hours old. This can be done as the backups take significantly less space and their generation is fast enough, to not change the performance of the servers.
Data Compression in Semi-dedicated Servers
If you host your websites in a semi-dedicated server account with our firm, you will be able to experience the advantages of LZ4 - the powerful compression algorithm used by the ZFS file system which is behind our advanced cloud web hosting platform. What differentiates LZ4 from all of the other algorithms out there is that it has a better compression ratio and it is much faster, in particular with regard to uncompressing web content. It does that even quicker than uncompressed info can be read from a hard drive, so your websites will perform better. The higher speed is at the expense of using plenty of CPU processing time, that is not an issue for our platform because it consists of a lot of clusters working together. Besides the improved performance, you will also have multiple daily backups at your disposal, so you can restore any deleted content with just a couple of clicks. The backup copies are available for an entire month and we can afford to keep them as they take significantly less space than traditional backups.
