Data compression is the compacting of information by decreasing the number of bits which are stored or transmitted. Consequently, the compressed data takes substantially less disk space than the original one, so extra content could be stored using the same amount of space. You will find many different compression algorithms which function in different ways and with a number of them just the redundant bits are deleted, which means that once the info is uncompressed, there's no loss of quality. Others remove unneeded bits, but uncompressing the data later will result in reduced quality in comparison with the original. Compressing and uncompressing content takes a large amount of system resources, and in particular CPU processing time, therefore any web hosting platform that uses compression in real time must have sufficient power to support this attribute. An example how data can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" how many consecutive 1s or 0s there should be instead of saving the entire code.
Data Compression in Shared Hosting
The ZFS file system which operates on our cloud Internet hosting platform employs a compression algorithm called LZ4. The aforementioned is substantially faster and better than any other algorithm available on the market, particularly for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data faster than it is read from a hard disk drive, which improves the performance of websites hosted on ZFS-based platforms. Due to the fact that the algorithm compresses data quite well and it does that very fast, we're able to generate several backups of all the content stored in the shared 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 fast, the backup generation will not change the performance of the hosting servers where your content will be stored.
Data Compression in Semi-dedicated Hosting
In case you host your Internet sites in a semi-dedicated hosting account from our company, you'll be able to experience the advantages of LZ4 - the powerful compression algorithm employed by the ZFS file system that's behind our advanced cloud Internet hosting platform. What separates LZ4 from all of the other algorithms out there is that it has a better compression ratio and it is considerably quicker, especially with regard to uncompressing web content. It does that even faster than uncompressed data can be read from a hard drive, so your websites will perform faster. The higher speed is at the expense of using lots of CPU processing time, that is not a problem for our platform as it consists of numerous clusters working together. Along with the superior performance, you'll have multiple daily backups at your disposal, so you could restore any deleted content with several clicks. The backups are available for a whole month and we can afford to store them because they need considerably less space compared to conventional backups.
