Data compression is the compacting of information by decreasing the number of bits that are stored or transmitted. Because of this, the compressed info will require much less disk space than the original one, so additional content could be stored on identical amount of space. You can find different compression algorithms which function in different ways and with many of them just the redundant bits are removed, therefore once the data is uncompressed, there is no loss of quality. Others remove excessive bits, but uncompressing the data later will lead to lower quality compared to the original. Compressing and uncompressing content takes a huge amount of system resources, and in particular CPU processing time, therefore each and every Internet hosting platform which uses compression in real time must have adequate power to support that feature. An example how data can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" what number of sequential 1s or 0s there should be instead of storing the entire code.
Data Compression in Hosting
The ZFS file system which operates on our cloud Internet hosting platform employs a compression algorithm called LZ4. The latter is considerably faster and better than any other algorithm available 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 Internet sites hosted on ZFS-based platforms. Because the algorithm compresses data really well and it does that very fast, we are able to generate several backups of all the content stored in the hosting accounts on our servers every day. Both your content and its backups will need reduced space and since both ZFS and LZ4 work very quickly, the backup generation will not affect the performance of the servers where your content will be stored.
Data Compression in Semi-dedicated Servers
If you host your sites in a semi-dedicated server account with our company, you will be able to experience the advantages of LZ4 - the powerful compression algorithm used by the ZFS file system that's behind our advanced cloud Internet hosting platform. What separates LZ4 from all other algorithms out there is that it has a better compression ratio and it is considerably faster, in particular when it comes to uncompressing website content. It does that even quicker than uncompressed data can be read from a hard disk drive, so your websites will perform better. The higher speed is at the expense of using a lot of CPU processing time, that's not an issue for our platform as it consists of a lot of clusters working together. In addition to the improved performance, you'll also have multiple daily backup copies at your disposal, so you can restore any deleted content with several clicks. The backup copies are available for an entire month and we can afford to store them as they take a lot less space than ordinary backups.
