Data compression is the reduction of the number of bits that should be saved or transmitted and the process is quite important in the internet hosting field as info filed on hard drives is often compressed so as to take less space. There're various algorithms for compressing information and they offer different effectiveness based upon the content. A lot of them remove just the redundant bits, so no data can be lost, while others delete unneeded bits, which results in worse quality once the data is uncompressed. The process requires a lot of processing time, therefore an internet hosting server should be powerful enough to be able to compress and uncompress data instantly. An illustration how binary code could be compressed is by "remembering" that there're five sequential 1s, for example, rather than storing all five 1s.
Data Compression in Website Hosting
The cloud hosting platform where your website hosting
account shall be generated uses the outstanding ZFS file system. The LZ4 compression method which the aforementioned employs is better in various aspects, and not only does it compress data better than any compression method that similar file systems use, but it's also much faster. The gains will be significant in particular on compressible content such as website files. Even though it could sound illogical, uncompressing data with LZ4 is quicker than reading uncompressed info from a hard disk drive, so the performance of any Internet site hosted on our servers will be better. The better and faster compression rates also allow us to produce multiple daily backups of the entire content in each and every hosting account, so if you delete anything by accident, the last back-up copy that we have won't be more than several hours old. This is possible because the backups take much less space and their generation is fast enough, so as to not change the performance of the servers.
Data Compression in Semi-dedicated Servers
The semi-dedicated server
plans that we supply are created on a powerful cloud hosting platform which runs on the ZFS file system. ZFS employs a compression algorithm called LZ4 that outperforms any other algorithm you will find in terms of speed and data compression ratio when it comes to processing web content. This is valid especially when data is uncompressed as 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 work at a higher speed. We're able to take full advantage of this feature regardless of the fact that it requires quite a lot of CPU processing time because our platform uses a large number of powerful servers working together and we don't create accounts on just a single machine like a lot of companies do. There is another benefit of using LZ4 - given that it compresses data very well and does that extremely fast, we can also make several daily backup copies of all accounts without influencing the performance of the servers and keep them for an entire month. By doing this, you'll always be able to recover any content that you erase by accident.
