The term data compression means reducing the number of bits of information that should be saved or transmitted. This can be done with or without losing info, so what will be removed during the compression can be either redundant data or unneeded one. When the data is uncompressed subsequently, in the first case the information and its quality shall be identical, while in the second case the quality will be worse. You can find various compression algorithms that are better for different type of info. Compressing and uncompressing data usually takes plenty of processing time, which means that the server executing the action must have ample resources to be able to process the info quick enough. A simple example how information can be compressed is to store how many sequential positions should have 1 and how many should have 0 in the binary code instead of storing the actual 1s and 0s.
Data Compression in Website Hosting
The compression algorithm which we use on the cloud hosting platform where your new website hosting
account shall be created is called LZ4 and it's applied by the cutting-edge ZFS file system which powers the platform. The algorithm is superior to the ones other file systems use since its compression ratio is much higher and it processes data a lot quicker. The speed is most noticeable when content is being uncompressed since this happens quicker than information can be read from a hdd. For that reason, LZ4 improves the performance of any website stored on a server that uses the algorithm. We use LZ4 in an additional way - its speed and compression ratio let us produce a couple of daily backup copies of the whole content of all accounts and keep them for 30 days. Not only do our backup copies take less space, but their generation does not slow the servers down like it can often happen with some other file systems.
Data Compression in Semi-dedicated Servers
In case you host your sites in a semi-dedicated server
account with our company, you'll be able to experience the advantages of LZ4 - the powerful compression algorithm used by the ZFS file system which is behind our advanced cloud hosting platform. What separates LZ4 from all other algorithms out there is that it has a higher compression ratio and it is considerably faster, especially when it comes to uncompressing web content. It does that even faster than uncompressed info can be read from a hard drive, so your websites will perform faster. The higher speed comes at the expense of using plenty of CPU processing time, that is not an issue for our platform since it consists of a large number of clusters working together. Besides the better performance, you will also have multiple daily backup copies at your disposal, so you can restore any deleted content with several clicks. The backups are available for a whole month and we can afford to keep them as they need significantly less space compared to conventional backups.
