The term data compression refers to lowering the number of bits of info that has to be saved or transmitted. You can do this with or without losing data, so what will be erased throughout the compression shall be either redundant data or unneeded one. When the data is uncompressed afterwards, in the first case the data and the quality shall be identical, whereas in the second case the quality shall be worse. You'll find various compression algorithms that are more effective for various type of information. Compressing and uncompressing data frequently takes plenty of processing time, which means that the server carrying out the action must have ample resources in order to be able to process your info quick enough. A simple example how information can be compressed is to store how many consecutive positions should have 1 and how many should have 0 inside the binary code instead of storing the actual 1s and 0s.

Data Compression in Shared Hosting

The cloud internet hosting platform where your shared hosting account shall be created employs the revolutionary ZFS file system. The LZ4 compression method which the aforementioned employs is superior in lots of aspects, and not only does it compress information better than any compression method which a number of other file systems use, but it is also considerably faster. The benefits will be significant in particular on compressible content like website files. Although it could sound illogical, uncompressing data with LZ4 is faster than reading uncompressed data from a hard disk, so the performance of each Internet site hosted on our servers shall be upgraded. The better and faster compression rates also allow us to generate a large number of daily backups of the whole content in each web hosting account, so should you delete something by accident, the last back-up copy which we have won't be more than a couple of hours old. This can be done as the backups take much less space and their generation is quick enough, to not affect the performance of our servers.

Data Compression in Semi-dedicated Servers

The semi-dedicated server plans that we offer are created on a powerful cloud hosting platform which runs on the ZFS file system. ZFS uses a compression algorithm called LZ4 that is superior to any other algorithm on the market in terms of speed and data compression ratio when it comes to processing web content. This is valid especially when data is uncompressed as LZ4 does that 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 faster. We can take full advantage of this feature regardless of the fact that it requires quite a great deal of CPU processing time as our platform uses numerous powerful servers working together and we don't make accounts on a single machine like the vast majority of companies do. There is one more advantage 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 affecting the performance of the servers and keep them for 30 days. This way, you can always bring back any content that you delete by mistake.
