The term data compression describes decreasing the number of bits of information that should be stored or transmitted. This can be achieved with or without losing information, so what will be removed throughout the compression shall be either redundant data or unnecessary one. When the data is uncompressed afterwards, in the first case the information and the quality will be identical, while in the second case the quality will be worse. You will find different compression algorithms which are better for different kind of data. Compressing and uncompressing data usually takes plenty of processing time, so the server executing the action needs to have sufficient resources to be able to process the data quick enough. One simple example how information can be compressed is to store just how many sequential positions should have 1 and how many should have 0 within the binary code rather than storing the actual 1s and 0s.
Data Compression in Shared Hosting
The cloud hosting platform where your shared hosting
account is made employs the impressive ZFS file system. The LZ4 compression method that the latter uses is superior in various aspects, and not only does it compress data better than any compression method that other file systems use, but it is also faster. The gains may be significant particularly on compressible content which includes website files. While it could sound unreasonable, uncompressing data with LZ4 is quicker than reading uncompressed info from a hard disk drive, so the performance of every website hosted on our servers will be upgraded. The better and faster compression rates also allow us to generate numerous daily backups of the full content in each web hosting account, so in the event you delete anything by accident, the last back-up copy which we have won't be more than a few hours old. This is possible as the backups take considerably less space and their generation is quick enough, so as to not influence the performance of the servers.
Data Compression in Semi-dedicated Hosting
In case you host your sites in a semi-dedicated hosting
account from our firm, you will be able to experience the advantages of LZ4 - the powerful compression algorithm used by the ZFS file system that is behind our advanced cloud Internet hosting platform. What differentiates LZ4 from all the other algorithms out there is that it has a better compression ratio and it is considerably quicker, especially with regard to uncompressing website content. It does that even quicker than uncompressed information can be read from a hard disk drive, so your sites will perform faster. The higher speed comes at the expense of using a lot of CPU processing time, that is not a problem for our platform since it consists of numerous clusters working together. In addition to the superior performance, you'll also have multiple daily backups at your disposal, so you could restore any deleted content with just a few clicks. The backup copies are available for a whole month and we can afford to store them because they need a lot less space compared to conventional backups.
