Data compression is the compacting of data by reducing the number of bits that are stored or transmitted. As a result, the compressed information will require much less disk space than the original one, so a lot more content can be stored on the same amount of space. You'll find different compression algorithms which work in different ways and with many of them just the redundant bits are deleted, so once the info is uncompressed, there is no loss of quality. Others remove unneeded bits, but uncompressing the data afterwards will result in reduced quality compared to the original. Compressing and uncompressing content takes a large amount of system resources, especially CPU processing time, so every web hosting platform which employs compression in real time should have ample power to support that attribute. An example how info can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" the number of consecutive 1s or 0s there should be instead of keeping the whole code.

Data Compression in Cloud Web Hosting

The compression algorithm that we employ on the cloud web hosting platform where your new cloud web hosting account will be created is called LZ4 and it's used by the advanced ZFS file system that powers the platform. The algorithm is more advanced than the ones other file systems employ since its compression ratio is much higher and it processes data a lot faster. The speed is most noticeable when content is being uncompressed as this happens more quickly than data can be read from a hard disk. As a result, LZ4 improves the performance of any site stored on a server which uses the algorithm. We use LZ4 in an additional way - its speed and compression ratio let us make multiple daily backups of the entire content of all accounts and store them for a month. Not only do these backup copies take less space, but in addition their generation won't slow the servers down like it can often happen with other file systems.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting plans which we offer are created on a powerful cloud hosting platform that runs on the ZFS file system. ZFS uses a compression algorithm known as LZ4 that exceeds any other algorithm you can find in terms of speed and data compression ratio when it comes to processing website content. This is valid particularly when data is uncompressed as LZ4 does that more quickly than it would be to read uncompressed data from a hard drive and owing to this, sites running on a platform where LZ4 is enabled will work quicker. We are able to take full advantage of this feature regardless of the fact that it needs quite a considerable amount of CPU processing time as our platform uses a lot of powerful servers working together and we don't create accounts on just a single machine like many companies do. There's an additional benefit of using LZ4 - given that it compresses data very well and does that very quickly, we can also make several daily backups of all accounts without influencing the performance of the servers and keep them for a whole month. In this way, you will always be able to recover any content that you delete by accident.
