The term data compression refers to reducing the number of bits of data that needs to be stored or transmitted. This can be achieved with or without the loss of data, which means that what will be deleted during the compression will be either redundant data or unneeded one. When the data is uncompressed later on, in the first case the info and the quality will be identical, while in the second case the quality shall be worse. There're various compression algorithms that are more efficient for different kind of data. Compressing and uncompressing data frequently takes a lot of processing time, so the server carrying out the action needs to have plenty of 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 inside the binary code as an alternative to storing the particular 1s and 0s.

Data Compression in Web Hosting

The cloud internet hosting platform where your web hosting account shall be generated uses the revolutionary ZFS file system. The LZ4 compression method which the aforementioned uses is better in lots of aspects, and not only does it compress data better than any compression method that similar file systems use, but it's also much quicker. The benefits are significant in particular on compressible content which includes website files. Although it may sound illogical, uncompressing data with LZ4 is faster than reading uncompressed data from a hard disk, so the performance of each Internet site hosted on our servers shall be better. The better and faster compression rates also allow us to produce multiple daily backups of the full content in every single hosting account, so should you delete something by mistake, the last back-up copy that we have will not be more than a couple of hours old. This can be done as the backups take significantly less space and their generation is fast enough, to not affect the performance of our servers.
