The term data compression refers to reducing the number of bits of info which has to be stored or transmitted. You can do this with or without the loss of information, so what will be deleted in the course of the compression can be either redundant data or unnecessary one. When the data is uncompressed afterwards, in the first case the information and its quality shall be the same, whereas in the second case the quality will be worse. There are different compression algorithms that are more efficient for different kind of information. Compressing and uncompressing data usually takes a lot of processing time, so the server carrying out the action should have sufficient resources in order to be able to process your data fast enough. An example how information can be compressed is to store just how many sequential positions should have 1 and just how many should have 0 in the binary code rather than storing the particular 1s and 0s.

Data Compression in Cloud Website Hosting

The compression algorithm which we employ on the cloud internet hosting platform where your new cloud website hosting account will be created is known as LZ4 and it is applied by the state-of-the-art ZFS file system which powers the system. The algorithm is better than the ones other file systems work with as its compression ratio is higher and it processes data considerably quicker. The speed is most noticeable when content is being uncompressed since this happens faster than info can be read from a hdd. Because of this, LZ4 improves the performance of each site stored on a server which uses this algorithm. We take full advantage of LZ4 in an additional way - its speed and compression ratio make it possible for us to generate a couple of daily backup copies of the full content of all accounts and keep them for a month. Not only do our backups take less space, but their generation doesn't slow the servers down like it can often happen with alternative file systems.
