The term data compression refers to decreasing the number of bits of data that should be stored or transmitted. This can be done with or without losing data, so what will be deleted throughout the compression will be either redundant data or unnecessary one. When the data is uncompressed afterwards, in the first case the info and its quality will be identical, while in the second case the quality shall be worse. There're different compression algorithms that are more effective for different kind of info. Compressing and uncompressing data usually takes lots of processing time, so the server performing the action should have ample resources to be able to process your data fast 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 Shared Hosting

The ZFS file system which operates on our cloud Internet hosting platform employs a compression algorithm called LZ4. The latter is considerably faster and better than any other algorithm out there, particularly for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data quicker than it is read from a hard drive, which improves the performance of sites hosted on ZFS-based platforms. Due to the fact that the algorithm compresses data really well and it does that very quickly, we can generate several backups of all the content stored in the shared hosting accounts on our servers on a daily basis. Both your content and its backups will require less space and since both ZFS and LZ4 work extremely fast, the backup generation will not affect the performance of the servers where your content will be kept.

Data Compression in Semi-dedicated Hosting

In case you host your sites in a semi-dedicated hosting account from our company, you can experience the advantages of LZ4 - the powerful compression algorithm employed by the ZFS file system that's behind our advanced cloud Internet hosting platform. What distinguishes LZ4 from all the other algorithms out there is that it has a better compression ratio and it is way quicker, especially when it comes to uncompressing website content. It does that even faster than uncompressed information can be read from a hard drive, so your sites will perform faster. The higher speed comes at the expense of using a great deal of CPU processing time, which is not an issue for our platform as it consists of a lot of clusters working together. Along with the improved performance, you'll have multiple daily backup copies at your disposal, so you could restore any deleted content with just a couple of clicks. The backup copies are available for a whole month and we can afford to keep them as they take a lot less space than conventional backups.
