The term data compression describes reducing the number of bits of data that should be saved or transmitted. You can do this with or without losing information, so what will be deleted in the course of the compression can be either redundant data or unneeded one. When the data is uncompressed later on, in the first case the data and its quality will 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 normally takes plenty of processing time, which means that the server performing the action needs to have plenty of resources to be able to process the info fast enough. A simple example how information can be compressed is to store just how many sequential positions should have 1 and how many should have 0 within the binary code instead of storing the particular 1s and 0s.
Data Compression in Cloud Web Hosting
The ZFS file system that operates on our cloud Internet hosting platform uses a compression algorithm called LZ4. The latter is a lot faster and better than every other algorithm out there, particularly for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data faster than it is read from a hard drive, which improves the overall performance of Internet sites hosted on ZFS-based platforms. As the algorithm compresses data very well and it does that very fast, we can generate several backup copies of all the content kept in the cloud web hosting
accounts on our servers on a daily basis. Both your content and its backups will require reduced space and since both ZFS and LZ4 work extremely fast, the backup generation will not affect the performance of the web servers where your content will be stored.
Data Compression in Semi-dedicated Hosting
In case you host your websites in a semi-dedicated hosting
account with our company, you can experience the advantages of LZ4 - the powerful compression algorithm employed by the ZFS file system that is behind our advanced cloud Internet hosting platform. What distinguishes LZ4 from all the other algorithms out there is that it has an improved compression ratio and it is way quicker, particularly with regard to uncompressing website content. It does that even faster than uncompressed info can be read from a hard disk drive, so your sites will perform faster. The higher speed is at the expense of using lots of CPU processing time, that is not an issue for our platform because it consists of a large number of clusters working together. Besides the better performance, you'll have multiple daily backup copies at your disposal, so you'll be able to recover any deleted content with several clicks. The backup copies are available for an entire month and we can afford to keep them since they take significantly less space compared to standard backups.
