The term data compression means lowering the number of bits of data which needs to be saved or transmitted. This can be achieved with or without the loss of information, which means that what will be deleted at the time of the compression shall be either redundant data or unnecessary one. When the data is uncompressed afterwards, in the first case the data and its quality will be the same, whereas in the second case the quality will be worse. You will find different compression algorithms which are more efficient for various kind of info. Compressing and uncompressing data in most cases takes plenty of processing time, so the server performing the action should have enough resources to be able to process the data fast enough. A simple example how information can be compressed is to store just how many sequential positions should have 1 and just how many should have 0 in the binary code rather than storing the actual 1s and 0s.
Data Compression in Shared Hosting
The compression algorithm which we use on the cloud web hosting platform where your new shared hosting account will be created is called LZ4 and it's used by the state-of-the-art ZFS file system that powers the system. The algorithm is more advanced than the ones other file systems use as its compression ratio is much higher and it processes data significantly quicker. The speed is most noticeable when content is being uncompressed as this happens faster than data can be read from a hard disk. As a result, LZ4 improves the performance of each website hosted on a server that uses the algorithm. We use LZ4 in an additional way - its speed and compression ratio allow us to produce a couple of daily backups of the full content of all accounts and store them for a month. Not only do our backups take less space, but also their generation doesn't slow the servers down like it can often happen with alternative file systems.
Data Compression in Semi-dedicated Servers
If you host your sites in a semi-dedicated server account with our firm, you can experience the advantages of LZ4 - the powerful compression algorithm employed by the ZFS file system which is behind our advanced cloud hosting platform. What differentiates LZ4 from all other algorithms out there is that it has an improved compression ratio and it is considerably faster, particularly with regard to uncompressing website content. It does that even quicker than uncompressed information can be read from a hard drive, so your sites will perform better. The higher speed is at the expense of using plenty of CPU processing time, that's not an issue for our platform since it consists of numerous clusters working together. In addition to the superior performance, you'll have multiple daily backup copies at your disposal, so you could recover any deleted content with just a few clicks. The backups are available for a whole month and we can afford to store them because they take significantly less space compared to conventional backups.
