The term data compression refers to lowering the number of bits of info which has to be stored or transmitted. This can be achieved with or without the loss of data, so what will be deleted throughout the compression can be either redundant data or unnecessary one. When the data is uncompressed afterwards, in the first case the info and its quality shall be the same, whereas in the second case the quality shall be worse. You'll find various compression algorithms that are better for various sort of information. Compressing and uncompressing data often takes lots of processing time, which means that the server performing the action needs to have sufficient resources to be able to process the info quick enough. A simple example how information can be compressed is to store just how many sequential positions should have 1 and just how many should have 0 within the binary code instead of storing the particular 1s and 0s.

Data Compression in Web Hosting

The ZFS file system that runs on our cloud Internet hosting platform employs a compression algorithm named LZ4. The latter is considerably faster and better than every other algorithm out there, particularly for compressing and uncompressing non-binary data i.e. web 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 backup copies of all the content stored in the web hosting accounts on our servers every day. Both your content and its backups will require reduced 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

The ZFS file system that runs on the cloud platform where your semi-dedicated server account will be created uses a powerful compression algorithm called LZ4. It is one of the best algorithms out there and definitely the most efficient one when it comes to compressing and uncompressing web content, as its ratio is very high and it will uncompress data quicker than the same data can be read from a hard disk drive if it were uncompressed. Thus, using LZ4 will boost any kind of website that runs on a platform where the algorithm is present. This high performance requires lots of CPU processing time, that's provided by the numerous clusters working together as part of our platform. In addition, LZ4 makes it possible for us to generate several backups of your content every day and have them for one month as they'll take a reduced amount of space than regular backups and will be created much faster without loading the servers.
