The term data compression means lowering the number of bits of info which should be saved or transmitted. This can be done with or without losing info, so what will be deleted during the compression can be either redundant data or unneeded one. When the data is uncompressed subsequently, in the first case the data and its quality will be identical, while in the second case the quality will be worse. There are various compression algorithms that are more efficient for various type of information. Compressing and uncompressing data in most cases takes lots of processing time, so the server performing the action should have sufficient resources to be able to process your info fast enough. A simple example how information can be compressed is to store just how many sequential positions should have 1 and how many should have 0 in the binary code as an alternative to storing the particular 1s and 0s.
Data Compression in Cloud Website Hosting
The cloud hosting platform where your cloud website hosting account shall be created uses the cutting-edge ZFS file system. The LZ4 compression method which the latter employs is better in various aspects, and not only does it compress info better than any compression method which many other file systems use, but it is also much quicker. The gains can be significant in particular on compressible content such as website files. While it could sound unreasonable, uncompressing data with LZ4 is faster than reading uncompressed info from a hard disk drive, so the performance of each website hosted on our servers shall be improved. The better and faster compression rates also allow us to make a large number of daily backups of the full content in each and every web hosting account, so in the event you delete something by accident, the last backup that we have will not be more than a couple of hours old. This can be done as the backups take considerably less space and their generation is fast enough, to not change the performance of our servers.
Data Compression in Semi-dedicated Hosting
In case you host your sites in a semi-dedicated hosting account with our company, you can experience the advantages of LZ4 - the powerful compression algorithm used by the ZFS file system that is behind our advanced cloud hosting platform. What distinguishes LZ4 from all of the other algorithms out there is that it has a better compression ratio and it is much quicker, in particular when it comes to uncompressing website content. It does that even quicker than uncompressed info can be read from a hard drive, so your websites will perform better. The higher speed comes at the expense of using plenty of CPU processing time, that's not an issue for our platform since it consists of a lot of clusters working together. In combination with the superior performance, you'll also have multiple daily backups at your disposal, so you will be able to restore any deleted content with a couple of clicks. The backups are available for a whole month and we can afford to keep them since they take significantly less space than standard backups.
