The term data compression identifies lowering the number of bits of information that should be stored or transmitted. This can be done with or without the loss of info, which means that what will be deleted at the time of the compression can be either redundant data or unnecessary one. When the data is uncompressed subsequently, in the first case the content and its quality will be identical, whereas in the second case the quality will be worse. You'll find various compression algorithms that are better for various sort of info. Compressing and uncompressing data in most cases takes a lot of processing time, therefore the server performing the action must have sufficient resources to be able to process the info fast enough. One simple example how information can be compressed is to store how many consecutive positions should have 1 and how many should have 0 within the binary code instead of storing the particular 1s and 0s.
Data Compression in Shared Hosting
The ZFS file system which operates on our cloud hosting platform employs a compression algorithm called LZ4. The aforementioned is significantly faster and better than every other algorithm available on the market, especially for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data quicker than it is read from a hard disk drive, which improves the performance of websites hosted on ZFS-based platforms. Because the algorithm compresses data quite well and it does that quickly, we are able to generate several backup copies of all the content stored in the shared hosting accounts on our servers on a daily basis. Both your content and its backups will need 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 kept.
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 employs a compression algorithm known as LZ4 that is greater than any other algorithm these days in terms of speed and data compression ratio when it comes to processing website content. This is valid especially when data is uncompressed because LZ4 does that more quickly than it would be to read uncompressed data from a hard drive and because of this, Internet sites running on a platform where LZ4 is present will function at a higher speed. We are able to benefit from the feature although it needs quite a large amount of CPU processing time because our platform uses a lot of powerful servers working together and we don't create accounts on a single machine like the majority of companies do. There's a further advantage of using LZ4 - considering the fact that it compresses data really 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 an entire month. This way, you'll always be able to bring back any content that you delete by accident.
