The term data compression describes reducing the number of bits of info which has to be saved or transmitted. This can be done with or without losing information, which means that what will be erased in the course of the compression can be either redundant data or unnecessary one. When the data is uncompressed later on, in the first case the data and its quality shall be the same, whereas in the second case the quality shall be worse. You'll find different compression algorithms that are better for different sort of information. Compressing and uncompressing data normally takes plenty of processing time, therefore the server performing the action must have enough resources in order to be able to process your data quick enough. A simple example how information can be compressed is to store just how many consecutive positions should have 1 and how many should have 0 in the binary code instead of storing the actual 1s and 0s.
Data Compression in Shared Web Hosting
The compression algorithm which we work with on the cloud web hosting platform where your new shared web hosting account shall be created is called LZ4 and it is applied by the exceptional ZFS file system which powers the system. The algorithm is more advanced than the ones other file systems employ since its compression ratio is a lot higher and it processes data significantly faster. The speed is most noticeable when content is being uncompressed since this happens more quickly than information can be read from a hard disk drive. For that reason, LZ4 improves the performance of each and every site hosted on a server which uses this algorithm. We take advantage of LZ4 in one more way - its speed and compression ratio let us generate multiple daily backups of the whole content of all accounts and keep them for one month. Not only do the backups take less space, but in addition their generation won't slow the servers down like it can often happen with some other file systems.
Data Compression in Semi-dedicated Servers
In case you host your websites in a semi-dedicated server account with our firm, you'll be able to experience the advantages of LZ4 - the powerful compression algorithm employed by the ZFS file system that is behind our advanced cloud Internet hosting platform. What distinguishes LZ4 from all of the other algorithms out there is that it has an improved compression ratio and it is considerably faster, particularly when it comes to uncompressing website content. It does that even faster 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 plenty of CPU processing time, which is not a problem for our platform because it consists of numerous clusters working together. Together with the better performance, you'll also have multiple daily backup copies at your disposal, so you can restore any deleted content with just a couple of clicks. The backup copies are available for an entire month and we can afford to store them as they need considerably less space compared to ordinary backups.
