The term data compression identifies lowering the number of bits of info that should be stored or transmitted. You can do this with or without losing info, which means that what will be deleted during the compression shall be either redundant data or unneeded one. When the data is uncompressed afterwards, in the first case the info and its quality will be identical, whereas in the second case the quality will be worse. You will find different compression algorithms that are better for different type of data. Compressing and uncompressing data usually takes lots of processing time, which means that the server carrying out the action must have sufficient resources to be able to process your data fast enough. An example how information can be compressed is to store how many consecutive positions should have 1 and how many should have 0 within the binary code instead of storing the actual 1s and 0s.

Data Compression in Web Hosting

The ZFS file system which runs on our cloud hosting platform uses a compression algorithm called LZ4. The latter is substantially faster and better than any other algorithm out there, particularly for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data faster than it is read from a hard drive, which improves the overall performance of sites hosted on ZFS-based platforms. Since the algorithm compresses data quite well and it does that quickly, we are able to generate several backups of all the content stored in the web hosting accounts on our servers daily. Both your content and its backups will require less space and since both ZFS and LZ4 work extremely fast, the backup generation will not affect the performance of the hosting servers where your content will be kept.

Data Compression in Semi-dedicated Servers

The semi-dedicated server plans which we offer are created on a powerful cloud platform which runs on the ZFS file system. ZFS works with a compression algorithm named LZ4 that outperforms any other algorithm these days 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 drive and owing to this, sites running on a platform where LZ4 is present will work at a higher speed. We're able to take advantage of the feature regardless of the fact that it needs quite a considerable amount of CPU processing time as our platform uses a number of powerful servers working together and we do not make accounts on just a single machine like the majority of companies do. There is an additional advantage of using LZ4 - considering the fact that it compresses data very well and does that extremely fast, we can also generate several daily backups of all accounts without influencing the performance of the servers and keep them for 30 days. By doing this, you can always bring back any content that you erase by mistake.
