The term data compression refers to reducing the number of bits of information which should be stored or transmitted. You can do this with or without the loss of information, so what will be removed throughout the compression shall be either redundant data or unneeded one. When the data is uncompressed later on, in the first case the information and its quality will be identical, while in the second case the quality will be worse. You can find different compression algorithms that are more effective for different type of info. Compressing and uncompressing data normally takes lots of processing time, therefore the server carrying out the action must have plenty of resources in order to be able to process the data quick enough. One simple example how information can be compressed is to store 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 Shared Website Hosting

The cloud web hosting platform where your shared website hosting account shall be generated uses the impressive ZFS file system. The LZ4 compression method which the aforementioned employs is greater in lots of aspects, and not only does it compress information better than any compression method which a variety of other file systems use, but it is also quicker. The benefits are significant in particular on compressible content like website files. Despite the fact that it could sound illogical, uncompressing data with LZ4 is quicker than reading uncompressed info from a hard disk drive, so the performance of each and every Internet site hosted on our servers shall be upgraded. The better and faster compression rates also make it possible for us to make a large number of daily backups of the full content in every single web hosting account, so should you delete something by mistake, the last back-up copy which we have will not be more than several hours old. This is possible as the backups take significantly less space and their generation is fast enough, to not affect the performance of our servers.

Data Compression in Semi-dedicated Servers

Your semi-dedicated server account shall be created on a cloud platform which is run on the leading-edge ZFS file system. The aforementioned uses a compression algorithm called LZ4, that is a lot better than various other algorithms with regard to compression ratio and speed. The gain is visible particularly 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 hard disk drive. This is why websites running on a platform that employs LZ4 compression perform faster as the algorithm is most efficient when it processes compressible data i.e. site content. One more advantage of using LZ4 is that the backups of the semi-dedicated accounts that we keep take significantly less space and they're generated a lot quicker, which allows us to store multiple daily backups of your files and databases.
