The term data compression refers to reducing the number of bits of info that has to be saved or transmitted. This can be achieved with or without losing info, so what will be erased in the course of the compression shall be either redundant data or unneeded one. When the data is uncompressed subsequently, in the first case the info and the quality will be identical, while in the second case the quality will be worse. There're different compression algorithms which are more efficient for various sort of data. Compressing and uncompressing data usually takes lots of processing time, so the server performing the action must have ample resources to be able to process your data fast enough. An example how information can be compressed is to store how many sequential positions should have 1 and just how many should have 0 within the binary code instead of storing the actual 1s and 0s.

Data Compression in Cloud Hosting

The compression algorithm that we employ on the cloud internet hosting platform where your new cloud hosting account will be created is named LZ4 and it's applied by the cutting-edge ZFS file system which powers the system. The algorithm is a lot better than the ones other file systems work with because its compression ratio is much higher and it processes data a lot faster. The speed is most noticeable when content is being uncompressed since this happens at a faster rate than info can be read from a hdd. As a result, LZ4 improves the performance of each website stored on a server that uses this particular algorithm. We use LZ4 in an additional way - its speed and compression ratio make it possible for us to generate several daily backups of the full content of all accounts and keep them for a month. Not only do the backups take less space, but their generation won't slow the servers down like it can often happen with alternative file systems.

Data Compression in Semi-dedicated Servers

The ZFS file system which runs on the cloud platform where your semi-dedicated server account will be created uses a powerful compression algorithm called LZ4. It is one of the best algorithms out there and certainly the best one when it comes to compressing and uncompressing website content, as its ratio is very high and it can uncompress data at a higher speed than the same data can be read from a hard disk drive if it were uncompressed. That way, using LZ4 will boost every site that runs on a platform where the algorithm is present. This high performance requires a lot of CPU processing time, that is provided by the numerous clusters working together as a part of our platform. In addition to that, LZ4 enables us to generate several backups of your content every day and save them for one month as they'll take a reduced amount of space than standard backups and will be created considerably faster without loading the servers.
