The term data compression means reducing the number of bits of info that needs to be stored or transmitted. You can do this with or without losing info, which means that what will be erased at the time of the compression will be either redundant data or unnecessary one. When the data is uncompressed later on, in the first case the content and its quality will be identical, whereas in the second case the quality shall be worse. You will find various compression algorithms that are more efficient for different type of info. Compressing and uncompressing data frequently takes a lot of processing time, so the server carrying out the action needs to have enough resources in order to be able to process your info fast enough. One simple example how information can be compressed is to store how many sequential positions should have 1 and just how many should have 0 in the binary code instead of storing the particular 1s and 0s.

Data Compression in Cloud Website Hosting

The ZFS file system which is run on our cloud web hosting platform employs a compression algorithm called LZ4. The aforementioned is a lot faster and better than any other algorithm on the market, especially for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data faster than it is read from a hard disk drive, which improves the overall performance of Internet sites hosted on ZFS-based platforms. Since the algorithm compresses data really well and it does that quickly, we're able to generate several backup copies of all the content stored in the cloud website hosting accounts on our servers daily. Both your content and its backups will take reduced space and since both ZFS and LZ4 work very quickly, the backup generation will not affect the performance of the web servers where your content will be stored.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting plans that we offer are created on a powerful cloud hosting platform that runs on the ZFS file system. ZFS works with a compression algorithm named LZ4 that is superior to any other algorithm available 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 quicker than it would be to read uncompressed data from a hard disk and for that reason, sites running on a platform where LZ4 is enabled will function quicker. We can benefit from this feature regardless of the fact that it requires quite a considerable amount of CPU processing time because our platform uses a lot of powerful servers working together and we don't 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 very well and does that very quickly, we can also generate multiple daily backups of all accounts without affecting the performance of the servers and keep them for a month. In this way, you can always bring back any content that you delete by accident.
