The term data compression refers to decreasing the number of bits of information that should be stored or transmitted. This can be done with or without losing information, so what will be removed at the time of the compression shall be either redundant data or unneeded one. When the data is uncompressed later on, in the first case the info and the quality will be identical, whereas in the second case the quality will be worse. You'll find various compression algorithms that are more effective for different kind of info. Compressing and uncompressing data normally takes lots of processing time, therefore the server executing the action must have sufficient resources to be able to process your info quick enough. A 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 Hosting
The ZFS file system which runs on our cloud web hosting platform employs a compression algorithm identified as LZ4. The aforementioned is a lot faster and better than every other algorithm available on the market, especially for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data faster than it is read from a hard disk drive, which improves the overall performance of websites hosted on ZFS-based platforms. Due to the fact that the algorithm compresses data very well and it does that very quickly, we're able to generate several backups of all the content kept in the hosting accounts on our servers every day. Both your content and its backups will require less space and since both ZFS and LZ4 work very fast, the backup generation will not affect the performance of the web servers where your content will be stored.
Data Compression in Semi-dedicated Servers
Your semi-dedicated server account shall be created on a cloud platform that runs on the innovative ZFS file system. The aforementioned uses a compression algorithm called LZ4, that is far better than various other algorithms in terms of compression ratio and speed. The gain is visible especially 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 hard disk drive. That's why websites running on a platform that uses LZ4 compression perform better since the algorithm is most effective when it processes compressible data i.e. web content. An additional advantage of using LZ4 is that the backups of the semi-dedicated accounts that we keep take a lot less space and are generated a lot quicker, which enables us to store a number of daily backups of your files and databases.
