The term data compression identifies decreasing the number of bits of info which has to be saved or transmitted. This can be achieved with or without losing data, which means that what will be erased in the course of the compression can be either redundant data or unneeded one. When the data is uncompressed subsequently, in the first case the content and the quality will be the same, whereas in the second case the quality shall be worse. There're different compression algorithms which are more effective for different sort of info. Compressing and uncompressing data in most cases takes lots of processing time, so the server executing the action should have enough resources to be able to process your data quick enough. An example how information can be compressed is to store just how many sequential positions should have 1 and just how many should have 0 inside the binary code as an alternative to storing the particular 1s and 0s.

Data Compression in Shared Hosting

The ZFS file system that is run on our cloud Internet hosting platform employs a compression algorithm called LZ4. The aforementioned is a lot faster and better than every other algorithm out there, especially for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data quicker than it is read from a hard disk drive, which improves the overall performance of websites hosted on ZFS-based platforms. Because the algorithm compresses data quite well and it does that very fast, we're able to generate several backup copies of all the content kept in the shared hosting accounts on our servers every day. Both your content and its backups will take reduced space and since both ZFS and LZ4 work very fast, the backup generation will not influence the performance of the web servers where your content will be stored.

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 uses a compression algorithm called LZ4 that exceeds any other algorithm available in terms of speed and data compression ratio when it comes to processing web content. This is valid especially when data is uncompressed because LZ4 does that much 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 function faster. We are able to benefit from the feature despite of the fact that it requires quite a large amount of CPU processing time as our platform uses a wide range of powerful servers working together and we never make accounts on just a single machine like the vast majority of companies do. There's another benefit of using LZ4 - considering the fact that it compresses data rather well and does that very fast, we can also generate multiple daily backup copies of all accounts without affecting the performance of the servers and keep them for a whole month. In this way, you can always bring back any content that you erase by accident.
