The term data compression identifies reducing the number of bits of info that has to be saved or transmitted. You can do this 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 subsequently, in the first case the info and its quality will be the same, whereas in the second case the quality will be worse. There're various compression algorithms which are more efficient for various type of information. Compressing and uncompressing data generally takes plenty of processing time, which means that the server carrying out the action needs to have plenty of resources to be able to process your info fast enough. A simple example how information can be compressed is to store how many sequential positions should have 1 and just how many should have 0 inside the binary code rather than storing the actual 1s and 0s.

Data Compression in Cloud Web Hosting

The compression algorithm that we work with on the cloud hosting platform where your new cloud web hosting account shall be created is known as LZ4 and it is applied by the exceptional ZFS file system which powers the system. The algorithm is greater than the ones other file systems use since its compression ratio is a lot higher and it processes data significantly quicker. The speed is most noticeable when content is being uncompressed since this happens faster than info can be read from a hdd. As a result, LZ4 improves the performance of each Internet site stored on a server that uses this algorithm. We take advantage of LZ4 in one more way - its speed and compression ratio allow us to produce multiple daily backups of the entire content of all accounts and keep them for a month. Not only do these backup copies take less space, but in addition their generation won't slow the servers down like it often happens with various other file systems.
