The term data compression identifies lowering the number of bits of info that has to be saved or transmitted. You can do this with or without the loss of info, so what will be deleted at the time of the compression will be either redundant data or unnecessary one. When the data is uncompressed afterwards, in the first case the info and the quality will be identical, while in the second case the quality shall be worse. You will find different compression algorithms that are more effective for different type of data. Compressing and uncompressing data normally takes lots of processing time, which means that the server carrying out the action should have adequate resources in order to be able to process your data 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 within the binary code instead of storing the particular 1s and 0s.
Data Compression in Shared Website Hosting
The cloud hosting platform where your shared website hosting
account is created uses the innovative ZFS file system. The LZ4 compression method that the aforementioned uses is greater in a number of aspects, and not only does it compress data better than any compression method that a variety of other file systems use, but it's also quicker. The gains may be significant in particular on compressible content which includes website files. Despite the fact that it may sound illogical, uncompressing data with LZ4 is faster than reading uncompressed data from a hard disk, so the performance of any website hosted on our servers will be boosted. The better and faster compression rates also make it possible for us to generate a large number of daily backups of the entire content in every single web hosting account, so if you delete something by accident, the last backup which we have won't be more than a few hours old. This is possible as the backups take much less space and their generation is fast enough, to not influence the performance of our servers.
