The term data compression refers to reducing the number of bits of info which should be stored or transmitted. This can be done with or without the loss of info, which means that what will be removed during the compression can be either redundant data or unneeded one. When the data is uncompressed afterwards, in the first case the information and the quality shall be the same, while in the second case the quality shall be worse. You will find various compression algorithms which are more effective for various type of data. Compressing and uncompressing data in most cases takes plenty of processing time, so the server performing the action should have sufficient resources to be able to process your data quick enough. A simple example how information can be compressed is to store how many sequential positions should have 1 and how many should have 0 inside the binary code rather than storing the actual 1s and 0s.
Data Compression in Website Hosting
The ZFS file system that runs on our cloud Internet hosting platform employs a compression algorithm identified as LZ4. The latter is considerably faster and better than any other algorithm on the market, 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 really well and it does that very quickly, we can generate several backup copies of all the content stored in the website hosting accounts on our servers on a daily basis. Both your content and its backups will need reduced space and since both ZFS and LZ4 work very fast, the backup generation will not affect the performance of the web hosting servers where your content will be kept.
Data Compression in Semi-dedicated Hosting
The semi-dedicated hosting plans that we supply are created on a powerful cloud hosting platform which runs on the ZFS file system. ZFS works with a compression algorithm called LZ4 that is superior to any other algorithm you can find in terms of speed and compression ratio when it comes to processing website content. This is valid especially when data is uncompressed as LZ4 does that more quickly 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 enabled will work at a higher speed. We can take full advantage of the feature regardless of the fact that it requires quite a lot of CPU processing time because our platform uses a large number of powerful servers working together and we never create accounts on a single machine like a lot of companies do. There is an additional reward of using LZ4 - since it compresses data rather well and does that very quickly, we can also make several daily backups of all accounts without influencing the performance of the servers and keep them for a whole month. By doing this, you'll always be able to recover any content that you delete by mistake.
