The term data compression describes reducing the number of bits of data that needs to be saved or transmitted. You can do this with or without the loss of info, so what will be deleted during the compression shall be either redundant data or unneeded one. When the data is uncompressed afterwards, in the first case the information and its quality shall be the same, while in the second case the quality shall be worse. You can find different compression algorithms that are more effective for various kind of data. Compressing and uncompressing data usually takes lots of processing time, so the server performing the action must have adequate resources in order to be able to process your info quick enough. An example how information can be compressed is to store how many consecutive 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 Website Hosting

The ZFS file system that runs on our cloud Internet hosting platform employs a compression algorithm called LZ4. The latter is significantly faster and better than any other algorithm you can find, especially for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data faster than it is read from a hard drive, which improves the overall performance of Internet sites hosted on ZFS-based platforms. Since the algorithm compresses data very well and it does that very quickly, we are able to generate several backups of all the content kept in the cloud website 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 influence the performance of the web 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 that is run on the leading-edge ZFS file system. The latter uses a compression algorithm called LZ4, that is a lot better than other algorithms when it comes to compression ratio and speed. The gain is apparent particularly when data is being uncompressed and not only is LZ4 faster than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a hard drive. Because of this websites running on a platform that employs LZ4 compression perform better because the algorithm is most effective when it processes compressible data i.e. web content. One more advantage of using LZ4 is that the backups of the semi-dedicated accounts that we keep require a lot less space and they are generated quicker, which allows us to keep several daily backups of all your files and databases.
