Data compression is the decrease of the number of bits which should be saved or transmitted and this process is quite important in the internet hosting field because information kept on hard disks is usually compressed to take less space. You'll find many different algorithms for compressing info and they offer different efficiency based on the content. A number of them remove only the redundant bits, so that no data can be lost, while others erase unnecessary bits, which leads to worse quality once the particular data is uncompressed. The process uses plenty of processing time, which means that an internet hosting server has to be powerful enough in order to be able to compress and uncompress data in real time. An example how binary code could be compressed is by "remembering" that there are five sequential 1s, for example, rather than storing all five 1s.

Data Compression in Shared Hosting

The compression algorithm used by the ZFS file system that runs on our cloud internet hosting platform is called LZ4. It can improve the performance of any website hosted in a shared hosting account on our end because not only does it compress info much better than algorithms employed by other file systems, but also uncompresses data at speeds which are higher than the HDD reading speeds. This is achieved by using a lot of CPU processing time, which is not a problem for our platform since it uses clusters of powerful servers working together. One more advantage of LZ4 is that it allows us to create backup copies much more quickly and on reduced disk space, so we can have multiple daily backups of your files and databases and their generation won't influence the performance of the servers. This way, we can always restore all content that you could have removed by accident.

Data Compression in Semi-dedicated Servers

The semi-dedicated server plans which we offer are created on a powerful cloud platform which runs on the ZFS file system. ZFS uses a compression algorithm known as LZ4 that surpasses any other algorithm on the market in terms of speed and compression ratio when it comes to processing web content. This is valid particularly when data is uncompressed as LZ4 does that a lot faster than it would be to read uncompressed data from a hard disk and as a result, sites running on a platform where LZ4 is present will work quicker. We are able to benefit from this feature despite of the fact that it requires quite a lot of CPU processing time because our platform uses a wide range of powerful servers working together and we don't create accounts on just a single machine like many companies do. There is one more reward of using LZ4 - since it compresses data rather 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 a month. By doing this, you will always be able to bring back any content that you delete by mistake.
