The term data compression refers to reducing the number of bits of information which needs to be saved or transmitted. This can be done with or without the loss of data, which means that what will be erased in the course of the compression shall be either redundant data or unneeded one. When the data is uncompressed later on, in the first case the information and its quality will be identical, whereas in the second case the quality will be worse. There're different compression algorithms which are more efficient for various type of info. Compressing and uncompressing data normally takes lots of processing time, which means that the server carrying out the action should have enough resources in order 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 in the binary code instead of storing the particular 1s and 0s.

Data Compression in Shared Website Hosting

The ZFS file system which operates on our cloud hosting platform uses a compression algorithm called LZ4. The aforementioned is significantly faster and better than every other algorithm you can find, particularly for compressing and uncompressing non-binary data i.e. internet 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. Due to the fact that the algorithm compresses data quite well and it does that very fast, we can generate several backups of all the content stored in the shared website hosting accounts on our servers daily. Both your content and its backups will take 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 kept.

Data Compression in Semi-dedicated Hosting

In case 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 that's behind our advanced cloud Internet hosting platform. What separates LZ4 from all the other algorithms out there is that it has a higher compression ratio and it is considerably quicker, especially with regard to uncompressing web content. It does that even quicker than uncompressed information can be read from a hard disk drive, so your websites will perform better. The higher speed comes at the expense of using a great deal of CPU processing time, which is not a problem for our platform since it consists of multiple clusters working together. Besides the improved performance, you'll have multiple daily backups at your disposal, so you will be able to restore any deleted content with just a few clicks. The backups are available for an entire month and we can afford to store them since they need considerably less space than ordinary backups.
