Data compression is the compacting of data 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 can be stored using the same amount of space. There're different compression algorithms that function in different ways and with many of them only the redundant bits are erased, therefore once the information is uncompressed, there's no loss of quality. Others delete excessive bits, but uncompressing the data later will lead to lower quality compared to the original. Compressing and uncompressing content takes a large amount of system resources, especially CPU processing time, therefore every web hosting platform which uses compression in real time must have ample power to support that feature. An example how data can be compressed is to replace 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 actual code.

Data Compression in Shared Hosting

The ZFS file system which runs on our cloud hosting platform employs a compression algorithm identified as LZ4. The latter is substantially faster and better than every other algorithm you can find, especially 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. Because the algorithm compresses data quite well and it does that very fast, we can generate several backup copies of all the content kept in the shared hosting accounts on our servers on a daily basis. 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 web hosting servers where your content will be kept.

Data Compression in Semi-dedicated Servers

In case you host your sites in a semi-dedicated server account from our firm, you'll 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 differentiates LZ4 from all other algorithms out there is that it has a higher compression ratio and it is much faster, especially with regard to uncompressing web content. It does that even quicker than uncompressed info can be read from a hard disk drive, so your websites will perform faster. The higher speed comes at the expense of using lots of CPU processing time, that is not a problem for our platform because it consists of numerous clusters working together. In addition to the improved performance, you'll have multiple daily backup copies at your disposal, so you'll be able to restore any deleted content with several clicks. The backups are available for an entire month and we can afford to store them as they take a lot less space than conventional backups.
