The term data compression refers to reducing the number of bits of information which needs to be saved or transmitted. This can be done with or without the loss of info, so what will be deleted at the time of the compression will be either redundant data or unnecessary one. When the data is uncompressed subsequently, in the first case the info and the quality shall be the same, whereas in the second case the quality will be worse. There are different compression algorithms which are better for various sort of info. Compressing and uncompressing data frequently takes a lot of processing time, therefore the server carrying out the action must have ample resources in order to be able to process your data quick 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 inside the binary code rather than 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 revolutionary ZFS file system that powers the system. The algorithm is superior to 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 as this happens even faster than info can be read from a hard disk. Therefore, LZ4 improves the performance of each site hosted on a server which uses the algorithm. We take full advantage of LZ4 in an additional way - its speed and compression ratio let us produce several daily backup copies of the full content of all accounts and keep them for thirty days. Not only do these backup copies take less space, but in addition their generation won't slow the servers down like it often happens with many other file systems.

Data Compression in Semi-dedicated Servers

Your semi-dedicated server account shall be created on a cloud platform that runs on the leading-edge ZFS file system. The latter uses a compression algorithm known as LZ4, that's 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 quicker in uncompressing data than a system is in reading from a hard disk. Because of this websites running on a platform that uses LZ4 compression perform better as the algorithm is most effective when it processes compressible data i.e. web content. Another advantage of using LZ4 is that the backup copies of the semi-dedicated accounts that we keep take a lot less space and they're generated quicker, which allows us to store multiple daily backups of all your files and databases.
