The term data compression means lowering the number of bits of info which has to be stored or transmitted. You can do this with or without the loss of information, which means that what will be deleted 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 data and its quality will be the same, while in the second case the quality will be worse. You will find various compression algorithms that are more effective for different kind of data. Compressing and uncompressing data in most cases takes lots of processing time, so the server carrying out the action needs to 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 sequential positions should have 1 and just how many should have 0 in the binary code rather than storing the particular 1s and 0s.

Data Compression in Website Hosting

The compression algorithm employed by the ZFS file system that runs on our cloud hosting platform is known as LZ4. It can improve the performance of any site hosted in a website hosting account on our end as not only does it compress data significantly better than algorithms used by various file systems, but it uncompresses data at speeds that are higher than the hard disk drive reading speeds. This is achieved by using a great deal of CPU processing time, that is not a problem for our platform because it uses clusters of powerful servers working together. One more advantage of LZ4 is that it allows us to make backups much more rapidly and on less disk space, so we can have multiple daily backups of your files and databases and their generation will not change the performance of the servers. In this way, we could always restore all of the content that you may have removed by mistake.
