Data compression is the compacting of info by reducing the number of bits that are stored or transmitted. As a result, the compressed data requires much less disk space than the original one, so extra content can be stored on identical amount of space. You can find many different compression algorithms which work in different ways and with a number of them only the redundant bits are erased, which means that once the information is uncompressed, there's no decrease in quality. Others remove excessive bits, but uncompressing the data afterwards will result in lower quality compared to the original. Compressing and uncompressing content requires a huge amount of system resources, particularly CPU processing time, therefore every Internet hosting platform which employs compression in real time needs to have enough 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" the number of consecutive 1s or 0s there should be instead of saving the whole code.

Data Compression in Shared Website Hosting

The cloud hosting platform where your shared website hosting account shall be created uses the impressive ZFS file system. The LZ4 compression method which the latter uses is better in numerous aspects, and not only does it compress information better than any compression method which some other file systems use, but it is also quicker. The benefits will be significant in particular on compressible content such as website files. Although it could sound illogical, uncompressing data with LZ4 is faster than reading uncompressed info from a hard disk drive, so the performance of every Internet site hosted on our servers will be boosted. The better and faster compression rates also allow us to generate a large number of daily backups of the entire content in every single web hosting account, so if you delete anything by accident, the last back-up copy which we have won't be more than several hours old. This is possible because the backups take significantly less space and their generation is fast enough, to not change the performance of the servers.

Data Compression in Semi-dedicated Servers

The semi-dedicated server plans which we offer are created on a powerful cloud platform that runs on the ZFS file system. ZFS employs a compression algorithm known as LZ4 that is greater than any other algorithm you can find in terms of speed and data compression ratio when it comes to processing website content. This is valid particularly when data is uncompressed since LZ4 does that a lot faster than it would be to read uncompressed data from a hard disk and owing to this, sites running on a platform where LZ4 is present will work quicker. We are able to take advantage of this feature although it requires quite a large amount of CPU processing time because our platform uses a huge number of powerful servers working together and we do not create accounts on a single machine like the majority of companies do. There is an additional reward of using LZ4 - since it compresses data really well and does that very quickly, we can also make multiple daily backup copies of all accounts without influencing the performance of the servers and keep them for a month. In this way, you'll always be able to recover any content that you delete by mistake.
