The term data compression means lowering the number of bits of info which should be saved or transmitted. This can be achieved with or without losing info, so what will be erased throughout the compression can be either redundant data or unneeded one. When the data is uncompressed afterwards, in the first case the information and its quality will be identical, while in the second case the quality shall be worse. You'll find different compression algorithms which are better for different sort of info. Compressing and uncompressing data usually takes plenty of processing time, so the server executing the action needs to have enough resources in order to be able to process your info quick 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 inside the binary code rather than storing the particular 1s and 0s.

Data Compression in Cloud Hosting

The cloud internet hosting platform where your cloud hosting account shall be made employs the cutting-edge ZFS file system. The LZ4 compression method that the latter uses is greater in a number of aspects, and not only does it compress data better than any compression method that many other file systems use, but it is also considerably quicker. The gains can be significant in particular on compressible content such as website files. Although it could sound irrational, uncompressing data with LZ4 is quicker than reading uncompressed info from a hard disk, so the performance of each and every site hosted on our servers shall be better. The better and quicker compression rates also allow us to make numerous daily backups of the full content in every single web hosting account, so if you delete anything by accident, the last backup which we have will not be more than a few hours old. This can be done as the backups take significantly less space and their generation is fast enough, so as to not affect the performance of the servers.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting plans which we provide are created on a powerful cloud hosting platform which runs on the ZFS file system. ZFS uses a compression algorithm called LZ4 that is better than any other algorithm you will find in terms of speed and data compression ratio when it comes to processing website content. This is valid especially when data is uncompressed because LZ4 does that quicker than it would be to read uncompressed data from a hard disk and because of this, sites running on a platform where LZ4 is present will work at a higher speed. We are able to take advantage of this feature regardless of the fact that it needs quite a large amount of CPU processing time because our platform uses numerous powerful servers working together and we do not make accounts on a single machine like a lot of companies do. There's one more advantage of using LZ4 - since it compresses data really well and does that extremely fast, we can also make several daily backup copies of all accounts without influencing the performance of the servers and keep them for an entire month. That way, you'll always be able to restore any content that you erase by accident.
