The term data compression describes decreasing the number of bits of information which should be saved or transmitted. You can do this with or without losing information, so what will be removed during the compression will be either redundant data or unneeded one. When the data is uncompressed later on, in the first case the content and the quality will be the same, whereas in the second case the quality shall be worse. You will find various compression algorithms which are better for different kind of information. Compressing and uncompressing data usually takes lots of processing time, therefore the server executing the action should have sufficient resources in order to be able to process your info quick enough. One simple example how information can be compressed is to store how many consecutive positions should have 1 and how many should have 0 inside the binary code as an alternative to storing the particular 1s and 0s.
Data Compression in Cloud Web Hosting
The compression algorithm that we employ on the cloud hosting platform where your new cloud web hosting account will be created is called LZ4 and it's used by the state-of-the-art ZFS file system which powers the platform. The algorithm is greater than the ones other file systems employ because 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 at a faster rate than info can be read from a hard drive. Because of this, LZ4 improves the performance of every site hosted on a server that uses the algorithm. We take full advantage of LZ4 in one more way - its speed and compression ratio make it possible for us to make a couple of daily backups of the full content of all accounts and store them for one month. Not only do our backups take less space, but also their generation does not slow the servers down like it often happens with various other file systems.
Data Compression in Semi-dedicated Servers
If you host your sites in a semi-dedicated server account from our firm, you can experience the advantages of LZ4 - the powerful compression algorithm employed by the ZFS file system that's behind our advanced cloud Internet hosting platform. What differentiates LZ4 from all the other algorithms out there is that it has a better compression ratio and it is much quicker, particularly with regard to uncompressing web content. It does that even faster than uncompressed data can be read from a hard disk drive, so your Internet sites will perform better. The higher speed comes at the expense of using a considerable amount of CPU processing time, which is not an issue for our platform because it consists of a lot of clusters working together. Along with the better performance, you will also have multiple daily backup copies at your disposal, so you'll be able to recover 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 because they take a lot less space than conventional backups.
