The term data compression refers to reducing the number of bits of data that should be stored or transmitted. You can do this with or without the loss of data, so what will be erased in the course of the compression can be either redundant data or unneeded one. When the data is uncompressed later on, in the first case the data and the quality will be the same, whereas in the second case the quality shall be worse. There are various compression algorithms which are more effective for different kind of data. Compressing and uncompressing data normally takes lots of processing time, so the server carrying out the action needs to have enough resources in order to be able to process the info quick enough. One simple example how information can be compressed is to store just how many sequential positions should have 1 and just how many should have 0 within the binary code as an alternative to storing the particular 1s and 0s.
Data Compression in Web Hosting
The compression algorithm that we use on the cloud web hosting platform where your new web hosting account shall be created is called LZ4 and it's applied by the advanced ZFS file system that powers the system. The algorithm is superior to the ones other file systems use since its compression ratio is a lot higher and it processes data considerably faster. The speed is most noticeable when content is being uncompressed as this happens more quickly than information can be read from a hard disk drive. Because of this, LZ4 improves the performance of any website located on a server that uses this particular algorithm. We use LZ4 in one more way - its speed and compression ratio make it possible for us to produce a couple of daily backup copies of the entire content of all accounts and keep them for 30 days. Not only do our backup copies take less space, but also their generation doesn't slow the servers down like it often happens with some other file systems.
Data Compression in Semi-dedicated Hosting
In case you host your websites in a semi-dedicated hosting account from our firm, you'll be able to experience the advantages of LZ4 - the powerful compression algorithm employed by the ZFS file system which is behind our advanced cloud hosting platform. What distinguishes LZ4 from all the other algorithms out there is that it has a better compression ratio and it is way quicker, in particular with regard to uncompressing website content. It does that even faster than uncompressed data can be read from a hard drive, so your websites will perform better. The higher speed is at the expense of using a considerable amount of CPU processing time, that's not an issue for our platform since it consists of a lot of clusters working together. Along with the superior performance, you'll have multiple daily backups at your disposal, so you could restore any deleted content with several clicks. The backup copies are available for a whole month and we can afford to store them as they take a lot less space than traditional backups.
