Data compression is the compacting of data by decreasing the number of bits which are stored or transmitted. As a result, the compressed data will require substantially less disk space than the original one, so a lot more content could be stored using identical amount of space. There're various compression algorithms which function in different ways and with some of them just the redundant bits are erased, therefore once the data is uncompressed, there is no decrease in quality. Others delete unnecessary bits, but uncompressing the data following that will result in lower quality in comparison with the original. Compressing and uncompressing content consumes a significant amount of system resources, in particular CPU processing time, therefore any hosting platform which uses compression in real time must have ample power to support this feature. An example how data can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" how many consecutive 1s or 0s there should be instead of storing the actual code.

Data Compression in Shared Web Hosting

The ZFS file system which is run on our cloud hosting platform employs a compression algorithm identified as LZ4. The latter is significantly faster and better than every other algorithm you'll find, particularly for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data faster than it is read from a hard disk, which improves the performance of websites hosted on ZFS-based platforms. Since the algorithm compresses data very well and it does that quickly, we are able to generate several backups of all the content kept in the shared web hosting accounts on our servers daily. Both your content and its backups will require reduced space and since both ZFS and LZ4 work very fast, the backup generation will not influence the performance of the hosting servers where your content will be kept.

Data Compression in Semi-dedicated Hosting

If 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 used by the ZFS file system that is behind our advanced cloud Internet hosting platform. What differentiates LZ4 from all of the other algorithms out there is that it has an improved compression ratio and it is much quicker, in particular when it comes to uncompressing web content. It does that even quicker than uncompressed information can be read from a hard drive, so your sites will perform faster. The higher speed comes at the expense of using a considerable amount of CPU processing time, that's not an issue for our platform since it consists of a lot of clusters working together. In addition to the superior performance, you will also have multiple daily backup copies at your disposal, so you'll be able to recover any deleted content with a couple of clicks. The backup copies are available for a whole month and we can afford to keep them because they need a lot less space than ordinary backups.
