The term data compression describes lowering the number of bits of data which needs to be stored or transmitted. This can be done with or without the loss of data, so what will be deleted throughout the compression can be either redundant data or unneeded one. When the data is uncompressed subsequently, in the first case the information and the quality will be the same, while in the second case the quality shall be worse. You can find different compression algorithms which are more efficient for different kind of information. Compressing and uncompressing data generally takes lots of processing time, so the server carrying out the action should have adequate resources to be able to process the data quick enough. A simple example how information can be compressed is to store just how many sequential positions should have 1 and how many should have 0 within the binary code rather than storing the particular 1s and 0s.

Data Compression in Shared Hosting

The compression algorithm used by the ZFS file system which runs on our cloud web hosting platform is called LZ4. It can enhance the performance of any website hosted in a shared hosting account with us as not only does it compress info significantly better than algorithms used by alternative file systems, but it uncompresses data at speeds which are higher than the hard disk drive reading speeds. This can be done by using a great deal of CPU processing time, which is not a problem for our platform for the reason that it uses clusters of powerful servers working together. A further advantage of LZ4 is that it allows us to create backup copies much quicker and on reduced disk space, so we shall have a couple of daily backups of your files and databases and their generation will not affect the performance of the servers. In this way, we could always recover any kind of content that you could have erased by accident.

Data Compression in Semi-dedicated Servers

If you host your sites in a semi-dedicated server account with 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 hosting platform. What differentiates LZ4 from all the other algorithms out there is that it has a higher compression ratio and it is much quicker, in particular with regard to uncompressing website content. It does that even faster than uncompressed data 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, that is not a problem for our platform as it consists of numerous clusters working together. Along with 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 backup copies are available for a whole month and we can afford to store them as they need significantly less space compared to traditional backups.
