The term data compression identifies decreasing the number of bits of info that should be stored or transmitted. This can be done with or without losing info, so what will be removed throughout the compression will be either redundant data or unnecessary one. When the data is uncompressed later on, in the first case the information and the quality will be identical, whereas in the second case the quality will be worse. You can find different compression algorithms that are more efficient for various kind of info. Compressing and uncompressing data usually takes a lot of processing time, which means that the server executing the action must have enough resources to be able to process the data quick enough. One simple example how information can be compressed is to store how many sequential positions should have 1 and how many should have 0 in the binary code as an alternative to storing the particular 1s and 0s.

Data Compression in Web Hosting

The cloud web hosting platform where your web hosting account is generated uses the impressive ZFS file system. The LZ4 compression method which the aforementioned employs is better in numerous aspects, and not only does it compress info better than any compression method that a number of other file systems use, but it's also considerably faster. The gains will be significant particularly on compressible content which includes website files. While it could sound irrational, uncompressing data with LZ4 is faster than reading uncompressed info from a hard disk drive, so the performance of any site hosted on our servers will be upgraded. The better and quicker compression rates also make it possible for us to produce a large number of daily backups of the entire content in each web hosting account, so should you delete anything by accident, the last back-up copy which we have will not be more than a few hours old. This can be done as the backups take significantly less space and their generation is quick enough, so as to not affect the performance of the servers.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting plans that we offer are created on a powerful cloud platform that runs on the ZFS file system. ZFS uses a compression algorithm known as LZ4 that is greater than any other algorithm out there in terms of speed and data compression ratio when it comes to processing web content. This is valid particularly when data is uncompressed since LZ4 does that faster than it would be to read uncompressed data from a hard disk and for that reason, Internet sites running on a platform where LZ4 is present will work at a higher speed. We can take advantage of the feature regardless of the fact that it needs quite a large amount of CPU processing time as our platform uses a huge number of powerful servers working together and we never create accounts on a single machine like many companies do. There is another advantage of using LZ4 - since it compresses data very well and does that very quickly, we can also make several daily backup copies of all accounts without affecting the performance of the servers and keep them for 30 days. That way, you will always be able to recover any content that you delete by accident.
