Data compression is the compacting of data by reducing the number of bits which are stored or transmitted. Because of this, the compressed info will require much less disk space than the original one, so additional content could be stored on identical amount of space. There are different compression algorithms that work in different ways and with a lot of them only the redundant bits are removed, so once the info is uncompressed, there's no loss of quality. Others remove unnecessary bits, but uncompressing the data following that will lead to lower quality in comparison with the original. Compressing and uncompressing content takes a huge amount of system resources, especially CPU processing time, therefore every web hosting platform which uses compression in real time needs to have adequate power to support this feature. An example how information can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" what number of sequential 1s or 0s there should be instead of keeping the actual code.
Data Compression in Shared Hosting
The cloud web hosting platform where your shared hosting account shall be created employs the outstanding ZFS file system. The LZ4 compression method which the aforementioned employs is greater in a number of aspects, and not only does it compress information better than any compression method which similar file systems use, but it's also considerably faster. The benefits will be significant especially on compressible content like website files. While it may sound illogical, uncompressing data with LZ4 is faster than reading uncompressed data from a hard disk, so the performance of any website hosted on our servers shall be improved. The better and quicker compression rates also make it possible for us to generate a large number of daily backups of the full content in every single hosting account, so in the event you delete something by accident, the last back-up copy that we have won't be more than several hours old. This is possible as the backups take much less space and their generation is fast enough, so as to not change the performance of our servers.
Data Compression in Semi-dedicated Hosting
Your semi-dedicated hosting account will be created on a cloud platform that runs on the innovative ZFS file system. The aforementioned uses a compression algorithm called LZ4, that's a lot better than all the other algorithms regarding 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 quicker in uncompressing data than a system is in reading from a HDD. This is the reason why Internet sites running on a platform which employs LZ4 compression perform faster because the algorithm is most efficient when it processes compressible data i.e. web content. Another advantage of using LZ4 is that the backups of the semi-dedicated accounts which we keep take much less space and they are generated quicker, which allows us to store a number of daily backups of all your files and databases.
