The term data compression describes lowering the number of bits of data that should be saved or transmitted. You can do this with or without the loss of info, which means that what will be removed during the compression shall be either redundant data or unnecessary one. When the data is uncompressed later on, in the first case the content and the quality shall be identical, while in the second case the quality will be worse. You can find different compression algorithms that are more efficient for various sort of info. Compressing and uncompressing data generally takes plenty of processing time, which means that the server performing the action needs to have ample resources to be able to process your info fast enough. One simple example how information can be compressed is to store just how many sequential positions should have 1 and how many should have 0 in the binary code instead of storing the particular 1s and 0s.

Data Compression in Web Hosting

The compression algorithm used by the ZFS file system which runs on our cloud internet hosting platform is called LZ4. It can supercharge the performance of any site hosted in a web hosting account with us since not only does it compress info more effectively than algorithms employed by alternative file systems, but also uncompresses data at speeds that are higher than the HDD reading speeds. This is achieved by using a great deal of CPU processing time, that is not a problem for our platform considering that it uses clusters of powerful servers working together. A further advantage of LZ4 is that it allows us to generate backups much more quickly and on less disk space, so we can have a couple of daily backups of your files and databases and their generation will not change the performance of the servers. That way, we could always recover any kind of content that you could have removed by mistake.
