Data compression is the lowering of the number of bits that should be saved or transmitted and the process is really important in the web hosting field because data located on HDDs is generally compressed to take less space. You'll find various algorithms for compressing data and they offer different effectiveness based on the content. Some of them remove just the redundant bits, so that no data will be lost, while others erase unnecessary bits, which leads to worse quality when the data is uncompressed. This method uses plenty of processing time, so a web hosting server should be powerful enough to be able to compress and uncompress data right away. An illustration how binary code can be compressed is by "remembering" that there're five consecutive 1s, for example, rather than storing all five 1s.

Data Compression in Cloud Hosting

The ZFS file system that is run on our cloud Internet hosting platform employs a compression algorithm named LZ4. The aforementioned is a lot faster and better than any other algorithm out there, especially for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data quicker than it is read from a hard drive, which improves the overall performance of sites hosted on ZFS-based platforms. Since the algorithm compresses data very well and it does that very quickly, we're able to generate several backups of all the content stored in the cloud hosting accounts on our servers on a daily basis. Both your content and its backups will need reduced space and since both ZFS and LZ4 work extremely fast, the backup generation will not change the performance of the web hosting servers where your content will be kept.

Data Compression in Semi-dedicated Servers

Your semi-dedicated server account will be created on a cloud platform which runs on the leading-edge ZFS file system. The latter uses a compression algorithm named LZ4, which is significantly better than other algorithms with regard to compression ratio and speed. The gain is visible particularly when data is being uncompressed and not only is LZ4 much faster than other algorithms, but it is also faster in uncompressing data than a system is in reading from a hard disk drive. That's why websites running on a platform which employs LZ4 compression perform faster since the algorithm is most effective when it processes compressible data i.e. website content. An additional advantage of using LZ4 is that the backup copies of the semi-dedicated accounts which we keep need less space and are generated a lot quicker, which allows us to keep several daily backups of your files and databases.
