Data compression is the compacting of information by lowering the number of bits which are stored or transmitted. This way, the compressed info will need much less disk space than the original one, so much more content could be stored on the same amount of space. There are different compression algorithms that work in different ways and with several of them just the redundant bits are erased, so once the data is uncompressed, there is no decrease in quality. Others remove unnecessary bits, but uncompressing the data later will lead to reduced quality compared to the original. Compressing and uncompressing content takes a huge amount of system resources, particularly CPU processing time, therefore each and every web hosting platform which uses compression in real time must have sufficient power to support this feature. An example how info can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" how many consecutive 1s or 0s there should be instead of keeping the actual code.

Data Compression in Cloud Web Hosting

The ZFS file system that runs on our cloud Internet hosting platform uses a compression algorithm called LZ4. The aforementioned is substantially faster and better than any other algorithm you'll find, particularly for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data faster than it is read from a hard drive, which improves the performance of websites hosted on ZFS-based platforms. Because the algorithm compresses data quite well and it does that quickly, we're able to generate several backups of all the content stored in the cloud web hosting accounts on our servers daily. Both your content and its backups will require less space and since both ZFS and LZ4 work very fast, the backup generation will not change the performance of the web servers where your content will be stored.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting plans that we provide are created on a powerful cloud hosting platform which runs on the ZFS file system. ZFS works with a compression algorithm called LZ4 that is greater than any other algorithm available in terms of speed and compression ratio when it comes to processing website content. This is valid especially when data is uncompressed as LZ4 does that a lot faster than it would be to read uncompressed data from a hard disk and for that reason, websites running on a platform where LZ4 is enabled will function quicker. We are able to take advantage of the feature regardless of the fact that it requires quite a great deal of CPU processing time as our platform uses a large number of powerful servers working together and we don't make accounts on just a single machine like a lot of companies do. There's another reward of using LZ4 - since it compresses data very well and does that extremely fast, we can also make multiple daily backups of all accounts without influencing the performance of the servers and keep them for 30 days. By doing this, you will always be able to recover any content that you delete by mistake.
