The term data compression describes lowering the number of bits of info which should be stored or transmitted. This can be achieved with or without losing info, which means that what will be removed throughout the compression will be either redundant data or unnecessary one. When the data is uncompressed afterwards, in the first case the content and the quality will be the same, whereas in the second case the quality shall be worse. There are different compression algorithms that are more efficient for various type of information. Compressing and uncompressing data frequently takes a lot of processing time, therefore the server executing the action must have plenty of resources in order to be able to process the data fast enough. An 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 Shared Hosting

The cloud web hosting platform where your shared hosting account shall be created uses the revolutionary ZFS file system. The LZ4 compression method which the latter employs is better in numerous aspects, and not only does it compress info better than any compression method that a variety of other file systems use, but it's also considerably quicker. The benefits can be significant particularly on compressible content which includes website files. While it may sound illogical, uncompressing data with LZ4 is quicker than reading uncompressed info from a hard drive, so the performance of each site hosted on our servers shall be upgraded. The better and faster compression rates also make it possible for us to produce a number of daily backups of the whole content in every single web hosting account, so in the event you delete anything by mistake, the last back-up copy which we have won't be more than a couple of hours old. This is possible because the backups take much less space and their generation is fast enough, so as to not affect the performance of our servers.
