Data compression is the compacting of info by reducing the number of bits which are stored or transmitted. In this way, the compressed info needs substantially less disk space than the original one, so extra content can be stored using the same amount of space. You will find various compression algorithms which work in different ways and with many of them just the redundant bits are deleted, which means that once the info is uncompressed, there is no loss of quality. Others erase unneeded bits, but uncompressing the data following that will lead to lower quality in comparison with the original. Compressing and uncompressing content consumes a significant amount of system resources, particularly CPU processing time, therefore any hosting platform that uses compression in real time must have ample power to support this attribute. An example how info can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" what number of consecutive 1s or 0s there should be instead of keeping the entire code.

Data Compression in Cloud Hosting

The cloud hosting platform where your cloud hosting account is created works by using the impressive ZFS file system. The LZ4 compression method which the aforementioned employs is better in many aspects, and not only does it compress data better than any compression method that many other file systems use, but it is also a lot quicker. The gains may be significant particularly on compressible content which includes website files. Even though it may sound unreasonable, uncompressing data with LZ4 is quicker than reading uncompressed info from a hard disk, so the performance of each and every site hosted on our servers shall be improved. The better and faster compression rates also make it possible for us to generate numerous daily backups of the whole content in each web hosting account, so should you delete something by accident, the last back-up copy which we have will not be more than several hours old. This can be done because the backups take a lot less space and their generation is fast enough, to not influence the performance of the servers.

Data Compression in Semi-dedicated Servers

Your semi-dedicated server account shall be created on a cloud platform that runs on the state-of-the-art ZFS file system. The aforementioned uses a compression algorithm named LZ4, that's a lot better than other algorithms when it comes to compression ratio and speed. The gain is significant particularly 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 drive. That's why websites running on a platform that employs LZ4 compression perform better as the algorithm is most efficient when it processes compressible data i.e. website content. Another advantage of using LZ4 is that the backups of the semi-dedicated accounts which we keep need much less space and are generated a lot quicker, which allows us to keep a couple of daily backups of all your files and databases.
