The term data compression means decreasing the number of bits of information that has to be stored or transmitted. This can be done with or without the loss of info, so what will be removed throughout the compression shall be either redundant data or unnecessary one. When the data is uncompressed later on, in the first case the info and its quality shall be identical, whereas in the second case the quality shall be worse. You will find various compression algorithms which are more efficient for different kind of information. Compressing and uncompressing data normally takes a lot of processing time, which means that the server performing the action must have adequate resources in order to be able to process your info quick enough. One simple example how information can be compressed is to store how many consecutive 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 Website Hosting

The compression algorithm that we employ on the cloud internet hosting platform where your new shared website hosting account shall be created is named LZ4 and it is applied by the state-of-the-art ZFS file system that powers the system. The algorithm is better than the ones other file systems work with as its compression ratio is higher and it processes data a lot faster. The speed is most noticeable when content is being uncompressed since this happens even faster than data can be read from a hdd. As a result, LZ4 improves the performance of each website hosted on a server that uses this particular algorithm. We take advantage of LZ4 in an additional way - its speed and compression ratio allow us to generate a couple of daily backup copies of the entire content of all accounts and keep them for one month. Not only do our backups take less space, but in addition their generation will not slow the servers down like it can often happen with various other file systems.

Data Compression in Semi-dedicated Servers

In case you host your sites in a semi-dedicated server account with our firm, you will be able to experience the advantages of LZ4 - the powerful compression algorithm employed by the ZFS file system that's behind our advanced cloud web hosting platform. What separates LZ4 from all of the other algorithms out there is that it has a higher compression ratio and it is much quicker, especially with regard to uncompressing website content. It does that even quicker than uncompressed information can be read from a hard drive, so your websites will perform better. The higher speed is at the expense of using a great deal of CPU processing time, that's not an issue for our platform because it consists of multiple clusters working together. Together with the better performance, you'll have multiple daily backups at your disposal, so you'll be able to recover any deleted content with a couple of clicks. The backup copies are available for a whole month and we can afford to keep them as they take significantly less space than standard backups.
