The term data compression refers to decreasing the number of bits of info that has to be saved or transmitted. This can be achieved with or without the loss of data, which means that what will be removed during the compression shall be either redundant data or unneeded one. When the data is uncompressed subsequently, in the first case the data and the quality will be the same, whereas in the second case the quality will be worse. There are various compression algorithms that are better for different kind of info. Compressing and uncompressing data frequently takes a lot of processing time, which means that the server performing the action must have adequate resources to be able to process the info quick enough. A simple example how information can be compressed is to store just how many consecutive positions should have 1 and just how many should have 0 within the binary code instead of storing the particular 1s and 0s.

Data Compression in Web Hosting

The ZFS file system that is run on our cloud web hosting platform uses a compression algorithm called LZ4. The latter is considerably faster and better than every other algorithm available on the market, especially for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data quicker than it is read from a hard disk drive, which improves the overall performance of websites hosted on ZFS-based platforms. Since the algorithm compresses data quite well and it does that quickly, we are able to generate several backup copies of all the content stored in the web hosting accounts on our servers on a daily basis. Both your content and its backups will need less 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 Hosting

Your semi-dedicated hosting account shall be created on a cloud platform which runs using the innovative ZFS file system. The aforementioned uses a compression algorithm named LZ4, that is a lot better than all other algorithms with regard to compression ratio and speed. The gain is significant particularly when data is being uncompressed and not only is LZ4 faster than other algorithms, but it is also faster in uncompressing data than a system is in reading from a HDD. That is why sites running on a platform that employs LZ4 compression perform faster because the algorithm is most efficient when it processes compressible data i.e. web content. One more advantage of using LZ4 is that the backup copies of the semi-dedicated accounts which we keep require significantly less space and are generated quicker, which enables us to store a number of daily backups of your files and databases.
