Data compression is the reduction of the number of bits that should be stored or transmitted and this particular process is quite important in the web hosting field due to the fact that info stored on HDDs is often compressed to take less space. There are many different algorithms for compressing data and they provide different efficiency based on the content. Many of them remove just the redundant bits, so no data will be lost, while others erase unneeded bits, which leads to worse quality when your data is uncompressed. The method consumes plenty of processing time, so a hosting server has to be powerful enough to be able to compress and uncompress data instantly. An example how binary code can be compressed is by "remembering" that there're five sequential 1s, for example, rather than storing all five 1s.
Data Compression in Shared Web Hosting
The ZFS file system that is run on our cloud Internet hosting platform uses a compression algorithm identified as LZ4. The latter is substantially faster and better than every other algorithm on the market, particularly for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data faster than it is read from a hard drive, which improves the overall performance of Internet sites hosted on ZFS-based platforms. Since the algorithm compresses data quite well and it does that very quickly, we are able to generate several backups of all the content stored in the shared web hosting accounts on our servers on a daily basis. Both your content and its backups will need reduced space and since both ZFS and LZ4 work very fast, the backup generation will not change the performance of the web hosting servers where your content will be kept.
Data Compression in Semi-dedicated Servers
The semi-dedicated server plans which we offer are created on a powerful cloud platform that runs on the ZFS file system. ZFS works with a compression algorithm known as LZ4 that is greater than any other algorithm you will find in terms of speed and compression ratio when it comes to processing website content. This is valid particularly when data is uncompressed since LZ4 does that more quickly 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 enabled will function at a higher speed. We are able to take full advantage of the feature regardless of the fact that it requires quite a lot of CPU processing time as our platform uses many powerful servers working together and we never create accounts on a single machine like many companies do. There's an additional benefit of using LZ4 - given that it compresses data rather well and does that very quickly, we can also make multiple daily backups of all accounts without affecting the performance of the servers and keep them for an entire month. By doing this, you will always be able to recover any content that you erase by accident.
