The term data compression identifies reducing the number of bits of info which has to be saved or transmitted. This can be done with or without losing data, which means that what will be erased in the course of the compression can be either redundant data or unneeded one. When the data is uncompressed afterwards, in the first case the content and its quality will be the same, whereas in the second case the quality shall be worse. You will find various compression algorithms which are more effective for different sort of info. Compressing and uncompressing data generally takes lots of processing time, therefore the server executing the action needs to have sufficient resources in order to be able to process your info quick 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 inside the binary code as an alternative to storing the actual 1s and 0s.

Data Compression in Hosting

The cloud internet hosting platform where your hosting account shall be created uses the outstanding ZFS file system. The LZ4 compression method that the latter uses is superior in lots of aspects, and not only does it compress data better than any compression method which a number of other file systems use, but it's also a lot quicker. The gains will be significant in particular on compressible content like website files. Despite the fact that it may sound illogical, uncompressing data with LZ4 is quicker than reading uncompressed data from a hard disk drive, so the performance of each and every site hosted on our servers will be upgraded. The better and faster compression rates also make it possible for us to generate numerous daily backups of the whole content in each and every hosting account, so in the event you delete something by mistake, the last back-up copy that we have won't be more than a few hours old. This is possible because the backups take a lot less space and their generation is quick enough, so as to not change the performance of the servers.

Data Compression in Semi-dedicated Servers

Your semi-dedicated server account will be created on a cloud platform which is run on the cutting-edge ZFS file system. The aforementioned uses a compression algorithm known as LZ4, which is much better than all the other algorithms with regard to compression ratio and speed. The gain is apparent especially when data is being uncompressed and not only is LZ4 faster than other algorithms, but it is also faster in uncompressing data than a system is in reading from a HDD. This is why websites running on a platform which uses LZ4 compression perform faster since the algorithm is most efficient when it processes compressible data i.e. site content. One more advantage of using LZ4 is that the backups of the semi-dedicated accounts which we keep need less space and are generated a lot faster, which allows us to store several daily backups of all your files and databases.
