The term data compression means lowering the number of bits of data which needs to be saved or transmitted. This can be achieved with or without losing info, which means that what will be removed during the compression can be either redundant data or unneeded one. When the data is uncompressed afterwards, in the first case the info and its quality shall be the same, whereas in the second case the quality will be worse. There're various compression algorithms which are more effective for various sort of info. Compressing and uncompressing data normally takes plenty of processing time, so the server executing the action must have ample resources in order to be able to process your data fast enough. One 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 in the binary code as an alternative to 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 created employs the reliable ZFS file system. The LZ4 compression method which the aforementioned employs is greater in lots of aspects, and not only does it compress data better than any compression method which many other file systems use, but it's also a lot faster. The gains will be significant in particular on compressible content such as website files. Despite the fact that it may sound irrational, uncompressing data with LZ4 is quicker than reading uncompressed data from a hard disk, so the performance of every site hosted on our servers will be boosted. The better and faster compression rates also allow us to produce a number of daily backups of the whole content in each web hosting account, so should you delete something by accident, the last back-up copy which we have won't be more than several hours old. This is possible because the backups take much less space and their generation is fast enough, to not influence the performance of our servers.
Data Compression in Semi-dedicated Servers
In case you host your Internet 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 which is behind our advanced cloud hosting platform. What differentiates LZ4 from all of the other algorithms out there is that it has an improved compression ratio and it is much quicker, especially with regard to uncompressing website content. It does that even faster than uncompressed info can be read from a hard disk drive, so your sites will perform better. The higher speed comes at the expense of using lots of CPU processing time, which is not a problem for our platform as it consists of a large number of clusters working together. Along with the superior performance, you will also have multiple daily backup copies at your disposal, so you'll be able to restore any deleted content with just a couple of clicks. The backup copies are available for an entire month and we can afford to keep them since they take a lot less space compared to traditional backups.
