The term data compression means lowering the number of bits of data which should be saved or transmitted. You can do this with or without losing information, which means that what will be removed at the time of the compression shall be either redundant data or unnecessary one. When the data is uncompressed later on, in the first case the info and the quality will be identical, while in the second case the quality shall be worse. There are various compression algorithms which are more effective for different type of data. Compressing and uncompressing data generally takes a lot of processing time, so the server performing the action must have enough resources in order to be able to process the data quick enough. An example how information can be compressed is to store how many consecutive positions should have 1 and just how many should have 0 within the binary code instead of storing the actual 1s and 0s.

Data Compression in Cloud Website Hosting

The ZFS file system that runs on our cloud web hosting platform employs a compression algorithm called LZ4. The latter is substantially faster and better than any other algorithm out there, 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, which improves the overall performance of Internet sites hosted on ZFS-based platforms. As the algorithm compresses data quite well and it does that very fast, we're able to generate several backup copies of all the content stored in the cloud website hosting accounts on our servers daily. Both your content and its backups will require less space and since both ZFS and LZ4 work extremely fast, the backup generation will not influence the performance of the web hosting servers where your content will be stored.

Data Compression in Semi-dedicated Servers

Your semi-dedicated server account will be created on a cloud platform which is run on the leading-edge ZFS file system. The aforementioned uses a compression algorithm called LZ4, which is far better than all the other algorithms with regard to compression ratio and speed. The gain is visible particularly 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 the reason why Internet sites running on a platform which uses LZ4 compression perform better as the algorithm is most effective when it processes compressible data i.e. website content. An additional advantage of using LZ4 is that the backups of the semi-dedicated accounts that we keep require much less space and are generated a lot faster, which allows us to have a couple of daily backups of your files and databases.
