The term data compression identifies decreasing the number of bits of info which has to be stored or transmitted. This can be achieved with or without the loss of information, so what will be deleted throughout the compression can be either redundant data or unneeded one. When the data is uncompressed later on, in the first case the data and its quality will be identical, whereas in the second case the quality will be worse. You can find various compression algorithms that are more effective for different kind of information. Compressing and uncompressing data normally takes plenty of processing time, so the server performing the action must have enough resources to be able to process your info fast enough. One simple example how information can be compressed is to store how many consecutive positions should have 1 and how many should have 0 within the binary code instead of storing the actual 1s and 0s.
Data Compression in Hosting
The cloud hosting platform where your hosting account shall be made uses the reliable ZFS file system. The LZ4 compression method which the aforementioned employs is better in a number of aspects, and not only does it compress information better than any compression method which a number of other file systems use, but it's also considerably faster. The gains may be significant in particular on compressible content like website files. Despite the fact that it could sound irrational, uncompressing data with LZ4 is faster than reading uncompressed data from a hard disk drive, so the performance of each website hosted on our servers will be upgraded. The better and quicker compression rates also allow us to produce a large number of daily backups of the whole content in each web hosting account, so should you delete anything by accident, the last back-up copy that we have won't be more than a couple of hours old. This is possible as the backups take much less space and their generation is fast enough, so as to not affect the performance of the servers.
Data Compression in Semi-dedicated Hosting
Your semi-dedicated hosting account will be created on a cloud platform which runs using the leading-edge ZFS file system. The latter uses a compression algorithm named LZ4, which is a lot better than various other algorithms when it comes to compression ratio and speed. The gain is apparent especially when data is being uncompressed and not only is LZ4 a lot faster than other algorithms, but it is also faster in uncompressing data than a system is in reading from a HDD. This is why sites running on a platform which employs LZ4 compression perform faster since the algorithm is most effective when it processes compressible data i.e. website content. One more advantage of using LZ4 is that the backup copies of the semi-dedicated accounts that we keep need much less space and they are generated a lot quicker, which enables us to keep a number of daily backups of your files and databases.
