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

Data Compression in Web Hosting

The cloud internet hosting platform where your web hosting account shall be generated employs the outstanding ZFS file system. The LZ4 compression method which the aforementioned employs is better in numerous aspects, and not only does it compress information better than any compression method that other file systems use, but it is also considerably faster. The gains may be significant particularly on compressible content such as website files. While it could sound irrational, uncompressing data with LZ4 is quicker than reading uncompressed data from a hard disk drive, so the performance of any site hosted on our servers will be upgraded. The better and faster compression rates also make it possible for us to make multiple daily backups of the whole content in each hosting account, so in the event you delete something by mistake, the last back-up copy that we have won't be more than a couple of hours old. This is possible because the backups take a lot less space and their generation is quick enough, to not change the performance of our servers.

Data Compression in Semi-dedicated Hosting

Your semi-dedicated hosting account will be created on a cloud platform which runs using the advanced ZFS file system. The latter uses a compression algorithm known as LZ4, which is a lot better than alternative algorithms regarding compression ratio and speed. The gain is visible especially when data is being uncompressed and not only is LZ4 quicker 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 better because the algorithm is most effective 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 need much less space and they are generated a lot quicker, which enables us to keep multiple daily backups of your files and databases.
