The term data compression refers to decreasing the number of bits of data that needs to be stored or transmitted. You can do this with or without the loss of info, so what will be deleted during the compression can be either redundant data or unneeded one. When the data is uncompressed later on, in the first case the info and its quality will be identical, whereas in the second case the quality will be worse. There're different compression algorithms that are more efficient for various type of information. Compressing and uncompressing data usually takes lots of processing time, which means that the server executing the action should have adequate resources in order to be able to process the data fast enough. One simple example how information can be compressed is to store just how many sequential positions should have 1 and just how many should have 0 inside the binary code instead of storing the actual 1s and 0s.

Data Compression in Website Hosting

The ZFS file system which runs on our cloud Internet hosting platform employs a compression algorithm named LZ4. The latter is a lot faster and better than every other algorithm on the market, especially for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data faster than it is read from a hard disk, which improves the performance of Internet sites hosted on ZFS-based platforms. Because the algorithm compresses data really well and it does that very quickly, we are able to generate several backups of all the content kept in the website hosting accounts on our servers on a daily basis. Both your content and its backups will require less space and since both ZFS and LZ4 work very quickly, the backup generation will not change the performance of the 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 that runs using the advanced ZFS file system. The latter uses a compression algorithm named LZ4, that is much better than all other algorithms with regard to compression ratio and speed. The gain is apparent especially when data is being uncompressed and not only is LZ4 quicker than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a HDD. That's why Internet sites running on a platform which uses LZ4 compression perform faster because the algorithm is most efficient when it processes compressible data i.e. web content. A further advantage of using LZ4 is that the backup copies of the semi-dedicated accounts that we keep take a lot less space and they are generated quicker, which allows us to keep several daily backups of your files and databases.
