The term data compression describes decreasing the number of bits of data that has to be saved or transmitted. You can do this with or without the loss of data, so what will be deleted 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 information and the quality will be the same, while in the second case the quality will be worse. You will find different compression algorithms which are more effective for different kind of information. Compressing and uncompressing data usually takes lots of processing time, so the server executing the action needs to have enough resources in order to be able to process the info fast enough. A simple example how information can be compressed is to store just how many consecutive positions should have 1 and how many should have 0 in the binary code instead of storing the actual 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 reliable ZFS file system. The LZ4 compression method that the latter employs is better in various aspects, and not only does it compress information better than any compression method which other file systems use, but it is also quicker. The gains may be significant especially on compressible content such as website files. While it could sound irrational, uncompressing data with LZ4 is faster than reading uncompressed info from a hard disk drive, so the performance of any website hosted on our servers will be improved. The better and faster compression rates also make it possible for us to generate a large number of daily backups of the full content in every single Internet hosting account, so if you delete something by mistake, the last back-up copy which we have won't be more than a couple of hours old. This can be done as the backups take a lot less space and their generation is quick enough, to not affect the performance of our servers.

Data Compression in Semi-dedicated Servers

In case you host your sites in a semi-dedicated server account with our company, you'll be able to experience the advantages of LZ4 - the powerful compression algorithm used by the ZFS file system that's behind our advanced cloud hosting platform. What separates LZ4 from all the other algorithms out there is that it has a higher compression ratio and it is considerably faster, in particular when it comes to uncompressing web content. It does that even faster than uncompressed data can be read from a hard disk drive, so your websites will perform faster. The higher speed comes at the expense of using a considerable amount of CPU processing time, that's not an issue for our platform as it consists of a lot of clusters working together. Besides the improved performance, you will also have multiple daily backup copies at your disposal, so you could recover any deleted content with a couple of clicks. The backup copies are available for a whole month and we can afford to keep them as they need a lot less space than ordinary backups.
