The term data compression describes reducing the number of bits of information which has to be saved or transmitted. This can be achieved with or without losing info, which means that what will be deleted at the time of the compression can be either redundant data or unnecessary one. When the data is uncompressed later on, in the first case the info and the quality will be the same, while in the second case the quality shall be worse. You will find various compression algorithms which are better for different type of information. Compressing and uncompressing data in most cases takes a lot of processing time, which means that the server performing the action should have adequate resources to be able to process the info fast enough. One simple example how information can be compressed is to store just how many sequential positions should have 1 and how many should have 0 within the binary code rather than storing the particular 1s and 0s.

Data Compression in Hosting

The ZFS file system which is run on our cloud hosting platform employs a compression algorithm called LZ4. The aforementioned is considerably faster and better than every other algorithm on the market, especially for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data faster than it is read from a hard drive, which improves the overall performance of websites hosted on ZFS-based platforms. As the algorithm compresses data very well and it does that very quickly, we can generate several backups of all the content stored in the hosting accounts on our servers daily. Both your content and its backups will require less space and since both ZFS and LZ4 work very quickly, the backup generation will not influence the performance of the web hosting servers where your content will be kept.

Data Compression in Semi-dedicated Servers

Your semi-dedicated server account shall be created on a cloud platform which runs on the advanced ZFS file system. The aforementioned uses a compression algorithm called LZ4, which is far better than all the other algorithms in terms of compression ratio and speed. The gain is apparent particularly when data is being uncompressed and not only is LZ4 much faster than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a hard drive. This is why websites running on a platform which uses LZ4 compression perform better because the algorithm is most effective when it processes compressible data i.e. site content. Another advantage of using LZ4 is that the backups of the semi-dedicated accounts that we keep take less space and they are generated a lot faster, which allows us to store a number of daily backups of all your files and databases.
