The term data compression refers to reducing the number of bits of data which needs to be stored or transmitted. This can be achieved with or without losing data, which means that what will be removed at the time of the compression will be either redundant data or unneeded one. When the data is uncompressed afterwards, in the first case the data and its quality shall be identical, whereas in the second case the quality shall be worse. There're various compression algorithms that are more effective for different sort of info. Compressing and uncompressing data usually takes a lot of processing time, therefore the server carrying out the action must have ample resources in order to be able to process your info quick enough. A simple 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 rather than storing the particular 1s and 0s.
Data Compression in Hosting
The ZFS file system that runs on our cloud Internet hosting platform employs a compression algorithm called LZ4. The aforementioned is substantially faster and better than every other algorithm you will find, particularly for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data quicker than it is read from a hard drive, which improves the performance of Internet sites hosted on ZFS-based platforms. As the algorithm compresses data really well and it does that quickly, we can generate several backup copies of all the content stored in the hosting accounts on our servers daily. Both your content and its backups will need reduced 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 stored.
Data Compression in Semi-dedicated Servers
The ZFS file system that runs on the cloud platform where your semi-dedicated server account will be created uses a powerful compression algorithm called LZ4. It is one of the best algorithms out there and certainly the most efficient one when it comes to compressing and uncompressing website content, as its ratio is very high and it will uncompress data at a higher speed than the same data can be read from a hard disk drive if it were uncompressed. This way, using LZ4 will speed up any kind of site that runs on a platform where this algorithm is present. This high performance requires a lot of CPU processing time, that's provided by the large number of clusters working together as a part of our platform. What's more, LZ4 enables us to generate several backups of your content every day and keep them for one month as they will take much less space than typical backups and will be generated much more quickly without loading the servers.
