The term data compression refers to reducing the number of bits of info which needs to be saved or transmitted. You can do this with or without losing information, so what will be removed throughout the compression will be either redundant data or unnecessary one. When the data is uncompressed afterwards, in the first case the content and its quality shall be the same, while in the second case the quality will be worse. There're different compression algorithms which are better for various sort of info. Compressing and uncompressing data normally takes lots of processing time, therefore the server performing the action needs to have sufficient resources to be able to process the info quick enough. An example how information can be compressed is to store how many consecutive positions should have 1 and how many should have 0 in the binary code rather than storing the particular 1s and 0s.
Data Compression in Cloud Hosting
The ZFS file system which is run on our cloud hosting platform uses a compression algorithm called LZ4. The latter is considerably faster and better than every 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 drive, which improves the overall performance of Internet sites hosted on ZFS-based platforms. As 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 cloud hosting accounts on our servers every day. Both your content and its backups will require less space and since both ZFS and LZ4 work extremely fast, the backup generation will not influence the performance of the web servers where your content will be stored.
Data Compression in Semi-dedicated Hosting
If you host your websites in a semi-dedicated hosting account from our company, you'll be able to experience the advantages of LZ4 - the powerful compression algorithm used by the ZFS file system which is behind our advanced cloud Internet hosting platform. What distinguishes LZ4 from all other algorithms out there is that it has a higher compression ratio and it is considerably faster, particularly when it comes to uncompressing web content. It does that even quicker than uncompressed information can be read from a hard disk drive, so your sites will perform better. The higher speed comes at the expense of using plenty of CPU processing time, which is not an issue for our platform since it consists of multiple clusters working together. Besides the superior performance, you'll also have multiple daily backups at your disposal, so you will be able to restore any deleted content with several clicks. The backups are available for an entire month and we can afford to keep them as they take a lot less space compared to traditional backups.
