The term data compression means decreasing the number of bits of info which needs to be saved or transmitted. This can be done with or without losing information, which means that what will be erased throughout the compression will be either redundant data or unnecessary one. When the data is uncompressed subsequently, in the first case the info and its quality will be the same, while in the second case the quality will be worse. There are different compression algorithms which are more efficient for various type of data. Compressing and uncompressing data normally takes lots of processing time, therefore the server performing the action should 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 how many consecutive positions should have 1 and just how many should have 0 within the binary code instead of storing the particular 1s and 0s.
Data Compression in Hosting
The compression algorithm that we work with on the cloud hosting platform where your new hosting account will be created is known as LZ4 and it's applied by the advanced ZFS file system that powers the platform. The algorithm is better than the ones other file systems employ since its compression ratio is a lot higher and it processes data a lot quicker. The speed is most noticeable when content is being uncompressed since this happens faster than information can be read from a hard disk. Because of this, LZ4 improves the performance of each Internet site stored on a server that uses the algorithm. We take advantage of LZ4 in an additional way - its speed and compression ratio let us make a number of daily backup copies of the full content of all accounts and keep them for one month. Not only do these backups take less space, but also their generation will not slow the servers down like it can often happen with alternative file systems.
Data Compression in Semi-dedicated Servers
Your semi-dedicated server account will be created on a cloud platform which runs using the innovative ZFS file system. The aforementioned uses a compression algorithm known as LZ4, that's far better than all other algorithms with regard to compression ratio and speed. The gain is significant particularly when data is being uncompressed and not only is LZ4 much quicker than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a HDD. That is why sites running on a platform that uses LZ4 compression perform faster as the algorithm is most effective when it processes compressible data i.e. site content. An additional advantage of using LZ4 is that the backup copies of the semi-dedicated accounts that we keep take much less space and they are generated a lot quicker, which allows us to store several daily backups of all your files and databases.
