The term data compression refers to reducing the number of bits of info which has to be stored or transmitted. You can do this with or without the loss of data, so what will be removed during the compression shall be either redundant data or unneeded one. When the data is uncompressed subsequently, in the first case the info and its quality will be the same, whereas in the second case the quality will be worse. You can find different compression algorithms that are better for various type of data. Compressing and uncompressing data usually takes lots of processing time, therefore the server performing the action needs to have ample resources in order to be able to process the data fast enough. One 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 within the binary code as an alternative to storing the particular 1s and 0s.

Data Compression in Shared Web Hosting

The compression algorithm which we use on the cloud internet hosting platform where your new shared web hosting account will be created is named LZ4 and it is applied by the advanced ZFS file system which powers the platform. The algorithm is more advanced than the ones other file systems work with as its compression ratio is a lot higher and it processes data considerably faster. The speed is most noticeable when content is being uncompressed as this happens quicker than information can be read from a hard disk. For that reason, LZ4 improves the performance of each and every Internet site located on a server which uses this algorithm. We take advantage of LZ4 in an additional way - its speed and compression ratio make it possible for us to generate a couple of daily backups of the entire content of all accounts and store 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 many other file systems.

Data Compression in Semi-dedicated Servers

In case you host your websites in a semi-dedicated server account from our firm, you will be able to experience the advantages of LZ4 - the powerful compression algorithm used by the ZFS file system which is behind our advanced cloud web hosting platform. What separates LZ4 from all the other algorithms out there is that it has an improved compression ratio and it is way quicker, in particular with regard to uncompressing website content. It does that even faster than uncompressed info can be read from a hard drive, so your websites will perform faster. The higher speed comes at the expense of using a great deal of CPU processing time, that is not an issue for our platform as it consists of multiple clusters working together. In addition to the superior performance, you will also have multiple daily backups at your disposal, so you can recover any deleted content with just 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 ordinary backups.
