The term data compression means reducing the number of bits of data that needs to be saved or transmitted. This can be achieved with or without the loss of data, so what will be deleted during the compression shall be either redundant data or unneeded one. When the data is uncompressed later on, in the first case the data and its quality will be identical, while in the second case the quality shall be worse. You can find different compression algorithms that are better for different type of info. Compressing and uncompressing data normally takes plenty of processing time, so the server performing the action needs to have ample resources to be able to process the 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 inside the binary code as an alternative to storing the actual 1s and 0s.

Data Compression in Cloud Hosting

The cloud web hosting platform where your cloud hosting account shall be made uses the revolutionary ZFS file system. The LZ4 compression method which the latter employs is superior in a number of aspects, and not only does it compress data better than any compression method that some other file systems use, but it is also faster. The gains can be significant especially on compressible content such as website files. Although it may sound unreasonable, uncompressing data with LZ4 is quicker than reading uncompressed info from a hard disk, so the performance of each site hosted on our servers will be upgraded. The better and quicker compression rates also make it possible for us to make numerous daily backups of the entire content in each Internet hosting account, so if you delete something by accident, the last backup which we have will not be more than several hours old. This is possible as the backups take much less space and their generation is fast enough, to not change the performance of the servers.
