Data compression is the compacting of data by reducing the number of bits that are stored or transmitted. Consequently, the compressed data will take considerably less disk space than the original one, so additional content could be stored on the same amount of space. You will find different compression algorithms which work in different ways and with some of them just the redundant bits are erased, therefore once the data is uncompressed, there's no decrease in quality. Others remove unnecessary bits, but uncompressing the data later on will lead to lower quality in comparison with the original. Compressing and uncompressing content requires a significant amount of system resources, in particular CPU processing time, so every web hosting platform that uses compression in real time should have sufficient power to support that attribute. An example how info can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" how many sequential 1s or 0s there should be instead of keeping the entire code.
Data Compression in Shared Web Hosting
The cloud web hosting platform where your shared web hosting
account will be made employs the impressive ZFS file system. The LZ4 compression method that the aforementioned employs is better in numerous aspects, and not only does it compress data better than any compression method which many other file systems use, but it's also quicker. The gains can be significant particularly on compressible content which includes website files. While it could sound irrational, uncompressing data with LZ4 is quicker than reading uncompressed data from a hard disk, so the performance of every site hosted on our servers shall be improved. The better and quicker compression rates also make it possible for us to generate multiple daily backups of the full content in every single Internet hosting account, so in the event you delete something by mistake, the last backup which we have won't be more than a few hours old. This can be done because the backups take much less space and their generation is fast enough, to not change the performance of our servers.
Data Compression in Semi-dedicated Servers
In case you host your sites in a semi-dedicated server
account from our firm, you will be able to experience the advantages of LZ4 - the powerful compression algorithm employed by the ZFS file system that is behind our advanced cloud hosting platform. What differentiates LZ4 from all the other algorithms out there is that it has a higher compression ratio and it is considerably faster, especially when it comes to uncompressing web content. It does that even faster than uncompressed data can be read from a hard disk drive, so your websites will perform better. The higher speed comes at the expense of using a considerable amount of CPU processing time, that's not an issue for our platform since it consists of a lot of clusters working together. Together with the improved performance, you'll also have multiple daily backups at your disposal, so you'll be able to recover any deleted content with several clicks. The backups are available for an entire month and we can afford to store them since they need considerably less space than traditional backups.
