The term data compression identifies reducing the number of bits of data that should be saved 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 unneeded one. When the data is uncompressed afterwards, in the first case the information and its quality will be the same, whereas in the second case the quality shall be worse. You can find different compression algorithms which are more efficient for various type of info. Compressing and uncompressing data generally takes a lot of processing time, therefore the server carrying out the action should have adequate resources to be able to process the info quick enough. A simple example how information can be compressed is to store just how many sequential positions should have 1 and just how many should have 0 in the binary code rather than storing the particular 1s and 0s.

Data Compression in Web Hosting

The ZFS file system which is run on our cloud web hosting platform uses a compression algorithm identified as LZ4. The aforementioned is considerably faster and better than every other algorithm you can find, especially for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data quicker than it is read from a hard disk drive, which improves the overall performance of Internet sites hosted on ZFS-based platforms. Because the algorithm compresses data very well and it does that very quickly, we're able to generate several backup copies of all the content kept in the web hosting accounts on our servers every day. Both your content and its backups will require reduced space and since both ZFS and LZ4 work very fast, 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 supply are created on a powerful cloud platform that runs on the ZFS file system. ZFS uses a compression algorithm called LZ4 that exceeds any other algorithm out there in terms of speed and compression ratio when it comes to processing website content. This is valid particularly when data is uncompressed because LZ4 does that a lot faster than it would be to read uncompressed data from a hard disk and for that reason, Internet sites running on a platform where LZ4 is present will function faster. We are able to benefit from this feature despite of the fact that it requires quite a considerable amount of CPU processing time as our platform uses a wide range of powerful servers working together and we never create accounts on just a single machine like many companies do. There's one more benefit of using LZ4 - since it compresses data very well and does that extremely fast, we can also generate multiple daily backups of all accounts without influencing the performance of the servers and keep them for 30 days. By doing this, you can always recover any content that you delete by mistake.
