The term data compression describes reducing the number of bits of information that should be stored or transmitted. This can be done with or without the loss of information, which means that what will be erased in the course of the compression shall be either redundant data or unneeded one. When the data is uncompressed subsequently, in the first case the information and its quality will be the same, whereas in the second case the quality shall be worse. There are different compression algorithms that are more effective for various sort of data. Compressing and uncompressing data usually takes plenty of processing time, therefore the server executing the action should have adequate resources in order to be able to process your info quick enough. A simple example how information can be compressed is to store how many consecutive positions should have 1 and 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 cloud web hosting platform where your shared web hosting account is made employs the impressive ZFS file system. The LZ4 compression method that the latter uses is superior in lots of aspects, and not only does it compress information better than any compression method which some other file systems use, but it's also considerably faster. The gains are significant in particular on compressible content such as website files. Although it could sound irrational, uncompressing data with LZ4 is quicker than reading uncompressed info from a hard disk, so the performance of every website hosted on our servers shall be improved. The better and quicker compression rates also allow us to make a number of daily backups of the whole content in every single hosting account, so should you delete something by mistake, the last backup that we have will not be more than a few hours old. This can be done as the backups take a lot less space and their generation is fast enough, to not influence the performance of our servers.
Data Compression in Semi-dedicated Servers
In case you host your Internet sites in a semi-dedicated server account from our firm, you'll be able to experience the advantages of LZ4 - the powerful compression algorithm used by the ZFS file system which is behind our advanced cloud hosting platform. What distinguishes LZ4 from all other algorithms out there is that it has a better compression ratio and it is much quicker, in particular with regard to uncompressing web content. It does that even faster than uncompressed data can be read from a hard disk drive, so your sites 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 a large number of clusters working together. In addition to the improved performance, you will also have multiple daily backups at your disposal, so you could recover any deleted content with just a few clicks. The backup copies are available for a whole month and we can afford to store them as they take considerably less space compared to traditional backups.
