The term data compression refers to lowering the number of bits of data which has to be stored or transmitted. You can do this with or without the loss of info, which means that what will be erased in the course of the compression can be either redundant data or unnecessary one. When the data is uncompressed afterwards, in the first case the content and its quality will be identical, whereas in the second case the quality will be worse. You'll find different compression algorithms that are better for different kind of info. Compressing and uncompressing data frequently takes plenty of processing time, therefore the server carrying out the action must have adequate resources to be able to process your info quick enough. An example how information can be compressed is to store just how many consecutive positions should have 1 and how many should have 0 in 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 is generated employs the innovative ZFS file system. The LZ4 compression method that the aforementioned uses is greater in lots of aspects, and not only does it compress data better than any compression method that other file systems use, but it is also faster. The benefits can be significant especially on compressible content which includes website files. Although it may sound irrational, uncompressing data with LZ4 is faster than reading uncompressed data from a hard disk, so the performance of every Internet site hosted on our servers will be better. The better and faster compression rates also allow us to produce a number of daily backups of the whole content in each and every Internet hosting account, so should you delete anything by mistake, the last back-up copy which we have won't be more than several hours old. This is possible because the backups take considerably less space and their generation is fast enough, so as to not change the performance of the servers.
