Data compression is the compacting of data by reducing the number of bits that are stored or transmitted. In this way, the compressed info takes considerably less disk space than the original one, so much more content might be stored using identical amount of space. You'll find various compression algorithms that function in different ways and with many of them only the redundant bits are removed, so once the information is uncompressed, there's no loss of quality. Others remove unnecessary bits, but uncompressing the data afterwards will lead to reduced quality in comparison with the original. Compressing and uncompressing content consumes a huge amount of system resources, especially CPU processing time, so any web hosting platform that uses compression in real time must have ample power to support this attribute. An example how info can be compressed is to substitute 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 Web Hosting

The cloud web hosting platform where your web hosting account is made employs the revolutionary ZFS file system. The LZ4 compression method that the latter employs is superior in many aspects, and not only does it compress information better than any compression method which a number of other file systems use, but it's also much quicker. The benefits are significant particularly on compressible content such as website files. Despite the fact that it may sound illogical, uncompressing data with LZ4 is faster than reading uncompressed info from a hard disk drive, so the performance of any Internet site hosted on our servers shall be upgraded. The better and quicker compression rates also allow us to make numerous daily backups of the whole content in each and every Internet hosting account, so should you delete anything by accident, the last back-up copy which we have won't be more than several hours old. This is possible as the backups take a lot less space and their generation is quick enough, to not affect the performance of our servers.

Data Compression in Semi-dedicated Servers

The semi-dedicated server plans that we provide are created on a powerful cloud hosting platform that runs on the ZFS file system. ZFS employs a compression algorithm known as LZ4 that outperforms any other algorithm these days in terms of speed and compression ratio when it comes to processing web content. This is valid particularly when data is uncompressed since LZ4 does that a lot faster than it would be to read uncompressed data from a hard drive and as a result, Internet sites running on a platform where LZ4 is present will work at a higher speed. We're able to take advantage of this feature although it needs quite a lot of CPU processing time as our platform uses many powerful servers working together and we don't make accounts on a single machine like a lot of companies do. There is an additional reward of using LZ4 - considering the fact that it compresses data rather well and does that extremely fast, we can also make multiple daily backups of all accounts without affecting the performance of the servers and keep them for a whole month. By doing this, you will always be able to bring back any content that you delete by accident.
