Data compression is the reduction of the number of bits which have to be saved or transmitted and this particular process is very important in the internet hosting field since information located on hard drives is generally compressed in order to take less space. You'll find different algorithms for compressing data and they provide different effectiveness depending on the content. Some of them remove just the redundant bits, so no data will be lost, while others remove unnecessary bits, which results in worse quality when the particular data is uncompressed. The method consumes a lot of processing time, therefore an internet hosting server needs to be powerful enough so as to be able to compress and uncompress data quickly. An illustration how binary code may be compressed is by "remembering" that there're five sequential 1s, for example, as an alternative to storing all five 1s.

Data Compression in Hosting

The compression algorithm that we work with on the cloud hosting platform where your new hosting account will be created is called LZ4 and it is applied by the leading-edge ZFS file system which powers the system. The algorithm is greater than the ones other file systems work with since its compression ratio is a lot higher and it processes data considerably quicker. The speed is most noticeable when content is being uncompressed as this happens faster than information can be read from a hard disk drive. As a result, LZ4 improves the performance of any Internet site stored on a server that uses this particular algorithm. We use LZ4 in an additional way - its speed and compression ratio make it possible for us to produce multiple daily backup copies of the full content of all accounts and store them for a month. Not only do these backups take less space, but their generation will not slow the servers down like it often happens with other file systems.

Data Compression in Semi-dedicated Servers

Your semi-dedicated server account will be created on a cloud platform which is run on the advanced ZFS file system. The latter uses a compression algorithm known as LZ4, that's a lot better than various other algorithms when it comes to compression ratio and speed. The gain is visible especially when data is being uncompressed and not only is LZ4 a lot faster than other algorithms, but it is also faster in uncompressing data than a system is in reading from a hard disk. That's why Internet sites running on a platform that employs LZ4 compression perform better since the algorithm is most efficient when it processes compressible data i.e. site content. Another advantage of using LZ4 is that the backups of the semi-dedicated accounts which we keep need a lot less space and they are generated quicker, which enables us to have a number of daily backups of all your files and databases.
