The term data compression refers to reducing the number of bits of data which needs to be saved or transmitted. You can do this with or without the loss of data, so what will be deleted during the compression can be either redundant data or unnecessary one. When the data is uncompressed afterwards, in the first case the data and its quality will be the same, whereas in the second case the quality will be worse. You'll find various compression algorithms that are more effective for various type of information. Compressing and uncompressing data frequently takes plenty of processing time, which means that the server executing the action should have plenty of resources in order to be able to process the info fast enough. One simple example how information can be compressed is to store how many consecutive positions should have 1 and just how many should have 0 inside the binary code instead of storing the particular 1s and 0s.

Data Compression in Cloud Web Hosting

The cloud internet hosting platform where your cloud web hosting account is created employs the revolutionary ZFS file system. The LZ4 compression method that the latter uses is greater in numerous aspects, and not only does it compress data better than any compression method that other file systems use, but it's also considerably faster. The gains may be significant in particular on compressible content like website files. Despite the fact that it may sound illogical, uncompressing data with LZ4 is faster than reading uncompressed info from a hard disk, so the performance of any site hosted on our servers shall be better. The better and quicker compression rates also allow us to make numerous daily backups of the whole content in each and every web hosting account, so in the event you delete anything by accident, the last back-up copy that we have won't be more than a few hours old. This is possible because the backups take significantly less space and their generation is quick enough, to not change the performance of the servers.
