The term data compression refers to lowering the number of bits of info that needs to be saved or transmitted. This can be achieved with or without the loss of info, which means that what will be deleted in the course of the compression shall be either redundant data or unnecessary one. When the data is uncompressed subsequently, in the first case the info 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 efficient for different type of data. Compressing and uncompressing data usually takes lots of processing time, which means that the server carrying out the action should have adequate resources in order to be able to process your info fast enough. An example how information can be compressed is to store how many sequential positions should have 1 and just how many should have 0 in the binary code instead of storing the particular 1s and 0s.

Data Compression in Cloud Web Hosting

The compression algorithm that we employ on the cloud web hosting platform where your new cloud web hosting account will be created is known as LZ4 and it's applied by the revolutionary ZFS file system which powers the platform. The algorithm is far better than the ones other file systems employ since its compression ratio is much higher and it processes data significantly quicker. The speed is most noticeable when content is being uncompressed since this happens even faster than info can be read from a hard disk drive. Consequently, LZ4 improves the performance of each Internet site located on a server which uses the algorithm. We take full advantage of LZ4 in one more way - its speed and compression ratio allow us to produce multiple daily backup copies of the whole content of all accounts and store them for one month. Not only do the backup copies take less space, but their generation does not slow the servers down like it often happens with alternative file systems.
