Data compression is the lowering of the number of bits which should be saved or transmitted and the process is very important in the web hosting field due to the fact that info located on HDDs is typically compressed to take less space. There're many different algorithms for compressing data and they provide different efficiency depending on the content. A number of them remove only the redundant bits, so no data can be lost, while others erase unnecessary bits, which results in worse quality once the data is uncompressed. This method uses plenty of processing time, therefore a hosting server should be powerful enough so as to be able to compress and uncompress data quickly. One example how binary code can be compressed is by "remembering" that there're five sequential 1s, for example, as an alternative to storing all five 1s.

Data Compression in Hosting

The ZFS file system which operates on our cloud Internet hosting platform employs a compression algorithm called LZ4. The aforementioned is considerably faster and better than any other algorithm you can find, particularly for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data quicker than it is read from a hard disk, which improves the performance of sites hosted on ZFS-based platforms. Since the algorithm compresses data very well and it does that very fast, we can generate several backups of all the content stored in the hosting accounts on our servers on a daily basis. Both your content and its backups will take reduced space and since both ZFS and LZ4 work very quickly, 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 which we offer are created on a powerful cloud platform which runs on the ZFS file system. ZFS employs a compression algorithm called LZ4 that surpasses any other algorithm out there in terms of speed and data compression ratio when it comes to processing website content. This is valid especially when data is uncompressed since LZ4 does that a lot faster than it would be to read uncompressed data from a hard disk and because of this, Internet sites running on a platform where LZ4 is present will work at a higher speed. We can take full advantage of this feature although it needs quite a lot of CPU processing time as our platform uses numerous powerful servers working together and we do not create accounts on a single machine like the vast majority of companies do. There is another benefit of using LZ4 - considering that it compresses data rather well and does that very fast, we can also generate multiple daily backups of all accounts without affecting the performance of the servers and keep them for a whole month. That way, you will always be able to bring back any content that you delete by mistake.
