Data compression is the reduction of the number of bits which need to be saved or transmitted and the process is very important in the web hosting field because info stored on hard disks is generally compressed in order to take less space. You can find various algorithms for compressing information and they have different efficiency depending on the content. Some of them remove just the redundant bits, so that no data can be lost, while others delete unnecessary bits, which results in worse quality when the data is uncompressed. The process consumes a lot of processing time, which means that a hosting server needs to be powerful enough so as to be able to compress and uncompress data instantly. An example how binary code could be compressed is by "remembering" that there're five consecutive 1s, for example, in contrast to storing all five 1s.
Data Compression in Hosting
The cloud internet hosting platform where your hosting account is created employs the reliable ZFS file system. The LZ4 compression method which the aforementioned uses is better in a number of aspects, and not only does it compress info better than any compression method that some other file systems use, but it's also considerably quicker. The gains will be significant especially on compressible content which includes website files. Although it may sound illogical, uncompressing data with LZ4 is quicker than reading uncompressed info from a hard disk drive, so the performance of each Internet site hosted on our servers will be improved. The better and quicker compression rates also allow us to generate a number of daily backups of the whole content in each and every Internet hosting account, so if you delete something by mistake, the last backup that we have will not be more than several hours old. This can be done because the backups take much less space and their generation is quick enough, to not influence the performance of our servers.
Data Compression in Semi-dedicated Servers
If you host your sites in a semi-dedicated server account from our firm, you can experience the advantages of LZ4 - the powerful compression algorithm used by the ZFS file system which is behind our advanced cloud hosting platform. What differentiates LZ4 from all the other algorithms out there is that it has a better compression ratio and it is way quicker, particularly when it comes to uncompressing web content. It does that even faster than uncompressed data can be read from a hard drive, so your Internet sites will perform better. The higher speed comes at the expense of using plenty of CPU processing time, that is not an issue for our platform because it consists of a lot of clusters working together. Together with the better performance, you will also have multiple daily backup copies at your disposal, so you could restore any deleted content with several clicks. The backups are available for a whole month and we can afford to store them since they take a lot less space than conventional backups.
