The term data compression describes decreasing the number of bits of info that should be stored or transmitted. You can do this with or without losing information, 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 later on, in the first case the data and the quality shall be identical, while in the second case the quality will be worse. You will find various compression algorithms which are better for different sort of data. Compressing and uncompressing data generally takes a lot of processing time, so the server executing the action must have enough resources to be able to process your data fast enough. A simple example how information can be compressed is to store how many sequential positions should have 1 and how many should have 0 within the binary code instead of storing the particular 1s and 0s.
Data Compression in Cloud Hosting
The cloud web hosting platform where your cloud hosting account shall be generated uses the revolutionary ZFS file system. The LZ4 compression method that the aforementioned employs is better 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's also a lot faster. The benefits are significant particularly on compressible content such as website files. While it could sound illogical, uncompressing data with LZ4 is faster than reading uncompressed info from a hard disk, so the performance of each and every site hosted on our servers shall be boosted. The better and quicker compression rates also allow us to generate a number of daily backups of the whole content in each and every web hosting account, so should you delete anything by accident, the last back-up copy which we have will not be more than several hours old. This can be done because the backups take considerably less space and their generation is quick enough, so as to not change the performance of the servers.
