Data compression is the decrease of the number of bits that have to be stored or transmitted and this particular process is really important in the web hosting field as information stored on HDDs is often compressed to take less space. You can find various algorithms for compressing data and they offer different effectiveness based on the content. A lot of them remove just the redundant bits, so no data will be lost, while others remove unnecessary bits, which results in worse quality once your data is uncompressed. This method needs plenty of processing time, so an internet hosting server needs to be powerful enough in order to be able to compress and uncompress data instantly. An example how binary code could be compressed is by "remembering" that there're five consecutive 1s, for example, as an alternative to storing all five 1s.

Data Compression in Shared Hosting

The compression algorithm that we work with on the cloud web hosting platform where your new shared 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 much better than the ones other file systems use because its compression ratio is a lot higher and it processes data significantly faster. The speed is most noticeable when content is being uncompressed as this happens even faster than information can be read from a hard disk drive. As a result, LZ4 improves the performance of each and every website hosted on a server which uses this algorithm. We take advantage of LZ4 in one more way - its speed and compression ratio let us generate a couple of daily backups of the entire content of all accounts and keep them for one month. Not only do our backup copies take less space, but also their generation will not slow the servers down like it often happens with some other file systems.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting plans that we offer are created on a powerful cloud platform which runs on the ZFS file system. ZFS employs a compression algorithm called LZ4 that outperforms any other algorithm you can find in terms of speed and data compression ratio when it comes to processing web content. This is valid especially when data is uncompressed since LZ4 does that quicker than it would be to read uncompressed data from a hard drive and for that reason, Internet sites running on a platform where LZ4 is present will function quicker. We are able to benefit from this feature regardless of the fact that it requires quite a great deal of CPU processing time because our platform uses a huge number of powerful servers working together and we never make accounts on just a single machine like the majority of companies do. There's one more advantage of using LZ4 - since it compresses data really well and does that speedily, 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 restore any content that you delete by accident.
