Data compression is the compacting of information by decreasing the number of bits that are stored or transmitted. Thus, the compressed information takes substantially less disk space than the initial one, so additional content can be stored on the same amount of space. You'll find different compression algorithms that function in different ways and with several of them just the redundant bits are erased, therefore once the information is uncompressed, there's no decrease in quality. Others delete excessive bits, but uncompressing the data later will result in reduced quality in comparison with the original. Compressing and uncompressing content consumes a large amount of system resources, in particular CPU processing time, therefore each and every web hosting platform that uses compression in real time should have enough power to support that feature. 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 Website Hosting
The cloud hosting platform where your shared website hosting account shall be created employs the cutting-edge ZFS file system. The LZ4 compression method that the aforementioned uses is superior in lots of aspects, and not only does it compress information better than any compression method which similar file systems use, but it is also considerably faster. The benefits will be significant particularly on compressible content such as website files. Despite the fact that it could sound unreasonable, uncompressing data with LZ4 is quicker than reading uncompressed data from a hard disk, so the performance of each and every website hosted on our servers shall be enhanced. The better and faster compression rates also make it possible for us to make a number of daily backups of the full content in each and every web hosting account, so in the event you delete anything by mistake, the last back-up copy which 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 fast enough, to not change the performance of the servers.
Data Compression in Semi-dedicated Hosting
In case you host your websites in a semi-dedicated hosting account with our firm, you will be able to experience the advantages of LZ4 - the powerful compression algorithm employed by the ZFS file system which is behind our advanced cloud hosting platform. What separates LZ4 from all other algorithms out there is that it has a higher compression ratio and it is considerably quicker, especially when it comes to uncompressing website content. It does that even faster than uncompressed data can be read from a hard disk drive, so your sites will perform better. The higher speed is at the expense of using lots of CPU processing time, that's not an issue for our platform as it consists of a lot of clusters working together. Together with the better performance, you'll also have multiple daily backups at your disposal, so you'll 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 because they need considerably less space compared to standard backups.
