The term data compression identifies lowering the number of bits of info that should be saved or transmitted. This can be achieved with or without the loss of data, which means that what will be deleted 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 the quality shall be the same, whereas in the second case the quality will be worse. You can find various compression algorithms which are more efficient for different type of data. Compressing and uncompressing data frequently takes a lot of processing time, therefore the server carrying out the action should have enough resources in order to be able to process your info 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 Web Hosting
The ZFS file system that is run on our cloud hosting platform employs a compression algorithm named LZ4. The latter is substantially faster and better than any other algorithm you can find, 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, which improves the overall performance of Internet sites hosted on ZFS-based platforms. Due to the fact that the algorithm compresses data very well and it does that very fast, we're able to generate several backup copies of all the content kept in the shared web hosting accounts on our servers daily. Both your content and its backups will need reduced space and since both ZFS and LZ4 work very fast, the backup generation will not influence the performance of the hosting 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 will 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 separates LZ4 from all other algorithms out there is that it has a better compression ratio and it is considerably faster, in particular 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 websites will perform faster. The higher speed comes at the expense of using a lot of CPU processing time, which is not an issue for our platform as it consists of multiple clusters working together. In addition to the superior performance, you'll have multiple daily backups at your disposal, so you could recover any deleted content with several clicks. The backups are available for an entire month and we can afford to keep them since they need considerably less space than conventional backups.
