Data compression is the lowering of the number of bits that should be stored or transmitted and this particular process is really important in the internet hosting field since data kept on HDDs is generally compressed in order to take less space. You'll find different algorithms for compressing information and they provide different effectiveness based upon the content. Many of them remove only the redundant bits, so that no data will be lost, while others delete unnecessary bits, which leads to worse quality when the data is uncompressed. This method needs a lot of processing time, therefore a web hosting server should be powerful enough to be able to compress and uncompress data instantly. An example how binary code may 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 ZFS file system which runs on our cloud Internet hosting platform uses a compression algorithm named LZ4. The aforementioned is a lot 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 faster than it is read from a hard disk, which improves the overall performance of Internet sites hosted on ZFS-based platforms. Because the algorithm compresses data quite well and it does that very quickly, we're able to generate several backup copies of all the content stored in the shared hosting accounts on our servers daily. Both your content and its backups will require less space and since both ZFS and LZ4 work very fast, the backup generation will not affect the performance of the web hosting servers where your content will be stored.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting plans that we provide are created on a powerful cloud hosting platform which runs on the ZFS file system. ZFS uses a compression algorithm named LZ4 that outperforms any other algorithm out there in terms of speed and compression ratio when it comes to processing website content. This is valid especially when data is uncompressed since LZ4 does that more rapidly than it would be to read uncompressed data from a hard drive and owing to this, sites running on a platform where LZ4 is enabled will work faster. We can take full advantage of this feature although it needs quite a great deal of CPU processing time as our platform uses many powerful servers working together and we never create accounts on just a single machine like a lot of companies do. There's one more advantage of using LZ4 - since it compresses data rather well and does that extremely fast, we can also generate several daily backup copies of all accounts without affecting the performance of the servers and keep them for 30 days. This way, you can always restore any content that you delete by accident.
