The term data compression identifies lowering the number of bits of info that has to be stored or transmitted. This can be achieved with or without the loss of information, which means that what will be erased 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 data 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 various kind of info. Compressing and uncompressing data generally takes a lot of processing time, therefore the server executing the action needs to have plenty of resources in order to be able to process the data fast enough. A simple example how information can be compressed is to store how many consecutive positions should have 1 and just how many should have 0 inside the binary code instead of storing the particular 1s and 0s.

Data Compression in Hosting

The compression algorithm that we work with on the cloud web hosting platform where your new hosting account will be created is known as LZ4 and it's applied by the exceptional ZFS file system that powers the platform. The algorithm is far better than the ones other file systems employ as its compression ratio is a lot higher and it processes data a lot quicker. The speed is most noticeable when content is being uncompressed as this happens faster than information can be read from a hard disk. Because of this, LZ4 improves the performance of every site stored on a server that uses the algorithm. We take advantage of LZ4 in one more way - its speed and compression ratio allow us to generate several daily backup copies of the whole content of all accounts and keep them for one month. Not only do our backups take less space, but also their generation will not slow the servers down like it often happens with alternative file systems.

Data Compression in Semi-dedicated Servers

If you host your sites in a semi-dedicated server account with our company, you can experience the advantages of LZ4 - the powerful compression algorithm employed by the ZFS file system that is behind our advanced cloud Internet hosting platform. What separates LZ4 from all the other algorithms out there is that it has a better compression ratio and it is way quicker, particularly with regard to uncompressing web content. It does that even faster than uncompressed information 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, which is not a problem for our platform since it consists of a lot of clusters working together. In addition to the improved performance, you will also have multiple daily backup copies at your disposal, so you can restore any deleted content with just a couple of clicks. The backups are available for a whole month and we can afford to store them because they take significantly less space than traditional backups.
