The term data compression means reducing the number of bits of info which should be saved or transmitted. This can be achieved with or without losing data, which means that what will be removed during the compression will be either redundant data or unnecessary one. When the data is uncompressed subsequently, in the first case the information and the quality shall be the same, while in the second case the quality will be worse. There're different compression algorithms which are more efficient for different kind of info. Compressing and uncompressing data generally takes lots of processing time, therefore the server performing the action must have ample resources in order to be able to process the data quick enough. One simple example how information can be compressed is to store how many sequential positions should have 1 and just how many should have 0 in the binary code instead of storing the particular 1s and 0s.
Data Compression in Shared Web Hosting
The cloud hosting platform where your shared web hosting
account shall be made employs the outstanding ZFS file system. The LZ4 compression method which the aforementioned uses is better in numerous aspects, and not only does it compress information better than any compression method which similar file systems use, but it's also faster. The benefits may be significant in particular on compressible content which includes website files. Even though it may sound irrational, uncompressing data with LZ4 is quicker than reading uncompressed data from a hard drive, so the performance of each and every website hosted on our servers will be boosted. The better and quicker compression rates also allow us to generate a large number of daily backups of the whole content in each and every Internet hosting account, so if you delete something by accident, the last backup that we have won't be more than a few hours old. This is possible because the backups take much less space and their generation is quick enough, to not affect the performance of the servers.
Data Compression in Semi-dedicated Servers
In case you host your websites in a semi-dedicated server
account from our company, you can 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 other algorithms out there is that it has an improved compression ratio and it is considerably faster, especially when it comes to uncompressing web content. It does that even faster than uncompressed info can be read from a hard drive, so your sites will perform faster. The higher speed is at the expense of using a great deal of CPU processing time, that is not a problem for our platform as it consists of a lot of clusters working together. Besides the superior performance, you'll have multiple daily backup copies at your disposal, so you will be able to restore any deleted content with several clicks. The backups are available for a whole month and we can afford to keep them since they take significantly less space than ordinary backups.
