The term data compression describes lowering the number of bits of info that has to be saved or transmitted. You can do this with or without losing information, which means that what will be deleted during the compression shall be either redundant data or unneeded one. When the data is uncompressed later on, in the first case the data and the quality shall be identical, while in the second case the quality will be worse. You can find different compression algorithms which are more effective for different kind of information. Compressing and uncompressing data usually takes lots of processing time, so the server executing the action must have ample resources in order to be able to process your info fast enough. One simple example how information can be compressed is to store just how many consecutive positions should have 1 and how many should have 0 inside the binary code instead of storing the particular 1s and 0s.

Data Compression in Cloud Hosting

The compression algorithm that we employ on the cloud web hosting platform where your new cloud hosting account shall be created is called LZ4 and it is used by the advanced ZFS file system that powers the system. The algorithm is better than the ones other file systems employ because 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 data can be read from a hdd. Because of this, LZ4 improves the performance of each Internet site stored on a server which uses this algorithm. We take advantage of LZ4 in an additional way - its speed and compression ratio make it possible for us to produce several daily backups of the full content of all accounts and keep them for thirty days. Not only do our backup copies take less space, but also their generation won't slow the servers down like it often happens with various other file systems.
