The term data compression refers to reducing the number of bits of data which has to be saved or transmitted. You can do this with or without the loss of data, which means that what will be erased in the course of the compression shall be either redundant data or unnecessary one. When the data is uncompressed later on, in the first case the information and its quality will be the same, whereas in the second case the quality shall be worse. You will find different compression algorithms that are more efficient for different sort of info. Compressing and uncompressing data normally takes plenty of processing time, which means that the server performing the action must have ample resources in order to be able to process the info fast enough. An example how information can be compressed is to store how many consecutive positions should have 1 and just how many should have 0 in the binary code instead of storing the particular 1s and 0s.

Data Compression in Shared Hosting

The cloud web hosting platform where your shared hosting account will be created works by using the cutting-edge ZFS file system. The LZ4 compression method which the aforementioned employs is greater in a number of aspects, and not only does it compress data better than any compression method that a variety of other file systems use, but it's also considerably faster. The gains may be significant in particular on compressible content such as website files. Even though it may sound irrational, uncompressing data with LZ4 is faster than reading uncompressed info from a hard disk, so the performance of every site hosted on our servers will be better. The better and faster compression rates also make it possible for us to produce a large number of daily backups of the entire content in every single hosting account, so in the event you delete something by mistake, the last back-up copy which we have won't be more than a few hours old. This is possible as the backups take considerably less space and their generation is quick enough, so as to not change the performance of the servers.

Data Compression in Semi-dedicated Servers

The semi-dedicated server plans which we supply are created on a powerful cloud platform which runs on the ZFS file system. ZFS works with a compression algorithm known as LZ4 that surpasses any other algorithm you will find in terms of speed and data compression ratio when it comes to processing website content. This is valid particularly when data is uncompressed as LZ4 does that faster than it would be to read uncompressed data from a hard disk drive and as a result, sites running on a platform where LZ4 is present will work at a higher speed. We can benefit from the feature despite of the fact that it needs quite a great deal of CPU processing time as our platform uses a wide range of powerful servers working together and we do not make accounts on a single machine like most companies do. There's another benefit of using LZ4 - considering the fact that it compresses data really well and does that very quickly, we can also make several daily backups of all accounts without affecting the performance of the servers and keep them for a month. This way, you can always recover any content that you erase by accident.
