Data compression is the compacting of information by reducing the number of bits which are stored or transmitted. This way, the compressed information will require considerably less disk space than the initial one, so extra content could be stored on the same amount of space. You will find many different compression algorithms which function in different ways and with several of them only the redundant bits are removed, therefore once the info is uncompressed, there's no decrease in quality. Others remove unnecessary bits, but uncompressing the data afterwards will result in reduced quality compared to the original. Compressing and uncompressing content consumes a huge amount of system resources, and in particular CPU processing time, therefore every web hosting platform which uses compression in real time must have enough power to support this feature. An example how information 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 Cloud Hosting
The ZFS file system that is run on our cloud Internet hosting platform uses a compression algorithm named LZ4. The latter is considerably faster and better than every other algorithm out there, 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 quite well and it does that very fast, we're able to generate several backup copies of all the content stored in the cloud 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 web servers where your content will be kept.
Data Compression in Semi-dedicated Servers
In case you host your Internet sites in a semi-dedicated server account with our company, you will be able to experience the advantages of LZ4 - the powerful compression algorithm employed by the ZFS file system which is behind our advanced cloud hosting platform. What separates LZ4 from all the other algorithms out there is that it has a higher compression ratio and it is much faster, particularly with regard to uncompressing web content. It does that even faster than uncompressed information can be read from a hard disk drive, so your Internet sites will perform better. The higher speed comes at the expense of using a considerable amount of CPU processing time, that's not an issue for our platform because it consists of a large number of clusters working together. Besides the superior performance, you will also have multiple daily backup copies at your disposal, so you can restore any deleted content with a few clicks. The backups are available for an entire month and we can afford to keep them as they take a lot less space than traditional backups.
