The term data compression identifies reducing the number of bits of data that should be saved or transmitted. You can do this with or without losing information, which means that what will be removed throughout the compression shall 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. There are various compression algorithms that are more efficient for different kind of info. Compressing and uncompressing data often takes plenty of processing time, so the server executing the action should have ample resources in order to be able to process the info fast 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 inside the binary code as an alternative to storing the actual 1s and 0s.

Data Compression in Cloud Website Hosting

The cloud web hosting platform where your cloud website hosting account will be made employs the outstanding ZFS file system. The LZ4 compression method which the aforementioned employs is greater in various aspects, and not only does it compress info better than any compression method which some other file systems use, but it's also much faster. The gains are significant especially on compressible content such as website files. Although it could sound unreasonable, uncompressing data with LZ4 is quicker than reading uncompressed info from a hard disk, so the performance of every Internet site hosted on our servers will be boosted. The better and quicker compression rates also make it possible for us to generate numerous daily backups of the full content in each Internet hosting account, so in the event you delete anything by mistake, the last backup that we have will not be more than a couple of hours old. This can be done because the backups take considerably less space and their generation is fast enough, so as to not change the performance of our servers.
