The term data compression refers to lowering the number of bits of data which has to be saved or transmitted. This can be achieved with or without losing data, so what will be removed at the time of the compression shall be either redundant data or unneeded one. When the data is uncompressed later on, in the first case the info and the quality will be the same, while in the second case the quality will be worse. You can find different compression algorithms that are more effective for different type of information. Compressing and uncompressing data often takes plenty of processing time, which means that the server executing the action should have sufficient resources in order to be able to process your data fast enough. A simple example how information can be compressed is to store just how many consecutive positions should have 1 and just how many should have 0 within the binary code as an alternative to storing the actual 1s and 0s.

Data Compression in Cloud Hosting

The ZFS file system which runs on our cloud web 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. web 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 fast, we can generate several backups of all the content stored in the cloud hosting accounts on our servers daily. Both your content and its backups will require less space and since both ZFS and LZ4 work very quickly, the backup generation will not change the performance of the hosting servers where your content will be stored.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting plans that we offer are created on a powerful cloud platform which runs on the ZFS file system. ZFS employs a compression algorithm called LZ4 that is better than any other algorithm you can find in terms of speed and data compression ratio when it comes to processing website content. This is valid especially when data is uncompressed as LZ4 does that quicker than it would be to read uncompressed data from a hard disk drive and for that reason, websites running on a platform where LZ4 is enabled will work faster. We are able to benefit from this feature although it needs quite a considerable amount of CPU processing time because our platform uses many powerful servers working together and we do not create accounts on a single machine like a lot of companies do. There is another reward of using LZ4 - since it compresses data rather well and does that very quickly, we can also make multiple daily backups of all accounts without influencing the performance of the servers and keep them for an entire month. This way, you will always be able to recover any content that you erase by accident.
