Data compression is the compacting of information by reducing the number of bits which are stored or transmitted. In this way, the compressed information will require considerably less disk space than the original one, so extra content could be stored using identical amount of space. You will find various compression algorithms that function in different ways and with a number of them only the redundant bits are removed, therefore once the info is uncompressed, there is no decrease in quality. Others erase excessive bits, but uncompressing the data at a later time will result in lower quality in comparison with the original. Compressing and uncompressing content requires a huge amount of system resources, especially CPU processing time, therefore any hosting platform which uses compression in real time must have enough power to support that attribute. An example how data can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" what number of sequential 1s or 0s there should be instead of keeping the actual code.

Data Compression in Hosting

The cloud hosting platform where your hosting account is created works by using the innovative ZFS file system. The LZ4 compression method which the latter uses is greater in numerous aspects, and not only does it compress info better than any compression method that a variety of other file systems use, but it is also faster. The gains are significant in particular on compressible content which includes website files. Although it could sound illogical, uncompressing data with LZ4 is quicker than reading uncompressed info from a hard disk, so the performance of every Internet site hosted on our servers shall be upgraded. The better and quicker compression rates also make it possible for us to make multiple daily backups of the entire content in each web hosting account, so should you delete something by accident, the last backup that we have will not be more than a couple of hours old. This can be done as the backups take significantly less space and their generation is fast enough, so as to not affect the performance of our servers.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting plans that we supply are created on a powerful cloud hosting platform that runs on the ZFS file system. ZFS uses a compression algorithm called LZ4 that surpasses any other algorithm you will find in terms of speed and data compression ratio when it comes to processing web content. This is valid especially when data is uncompressed because LZ4 does that much faster than it would be to read uncompressed data from a hard drive and owing to this, sites running on a platform where LZ4 is present will function quicker. We are able to take full advantage of the feature regardless of the fact that it needs quite a great deal of CPU processing time because our platform uses a number of powerful servers working together and we don't create accounts on a single machine like most companies do. There's a further reward of using LZ4 - considering the fact that it compresses data very well and does that very fast, we can also generate multiple daily backups of all accounts without affecting the performance of the servers and keep them for 30 days. That way, you will always be able to bring back any content that you erase by mistake.
