Data compression is the compacting of data by lowering the number of bits that are stored or transmitted. This way, the compressed data needs considerably less disk space than the original one, so a lot more content can be stored using identical amount of space. There're different compression algorithms which work in different ways and with some of them only the redundant bits are erased, so once the info is uncompressed, there's no decrease in quality. Others erase unneeded bits, but uncompressing the data following that will result in reduced quality compared to the original. Compressing and uncompressing content consumes a large amount of system resources, in particular CPU processing time, therefore every hosting platform that uses compression in real time must have enough power to support that feature. An example how info 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 compression algorithm which we employ on the cloud web hosting platform where your new shared hosting account shall be created is known as LZ4 and it's applied by the cutting-edge ZFS file system that powers the system. The algorithm is far better than the ones other file systems employ since its compression ratio is a lot higher and it processes data significantly faster. The speed is most noticeable when content is being uncompressed since this happens quicker than data can be read from a hard disk drive. As a result, LZ4 improves the performance of any Internet site hosted on a server which uses this algorithm. We take advantage of LZ4 in an additional way - its speed and compression ratio make it possible for us to make several daily backup copies of the whole content of all accounts and keep them for a month. Not only do these backups take less space, but also their generation won't slow the servers down like it can often happen with other file systems.

Data Compression in Semi-dedicated Servers

If you host your sites in a semi-dedicated server account from our company, you can 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 other algorithms out there is that it has an improved compression ratio and it is considerably quicker, 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 websites will perform better. The higher speed is at the expense of using plenty of CPU processing time, that is not a problem for our platform as it consists of numerous clusters working together. Together with 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 just a couple of clicks. The backup copies are available for an entire month and we can afford to store them as they need significantly less space compared to traditional backups.
