The term data compression means lowering the number of bits of info that has to be stored or transmitted. You can do this with or without the loss of info, which means that what will be deleted at the time of the compression can be either redundant data or unnecessary one. When the data is uncompressed subsequently, in the first case the info and its quality shall be the same, whereas in the second case the quality shall be worse. There are various compression algorithms that are more efficient for various sort of information. Compressing and uncompressing data generally takes plenty of processing time, therefore the server carrying out the action must have adequate resources in order to be able to process the info fast enough. One 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 instead of storing the particular 1s and 0s.
Data Compression in Cloud Website Hosting
The ZFS file system that runs on our cloud hosting platform uses a compression algorithm called LZ4. The latter is a lot faster and better than every other algorithm available on the market, particularly for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data quicker than it is read from a hard disk drive, which improves the performance of Internet sites hosted on ZFS-based platforms. Because the algorithm compresses data quite well and it does that quickly, we are able to generate several backups of all the content kept in the cloud website hosting accounts on our servers every day. Both your content and its backups will take reduced space and since both ZFS and LZ4 work very quickly, the backup generation will not influence the performance of the web servers where your content will be kept.
Data Compression in Semi-dedicated Hosting
The semi-dedicated hosting plans that we supply are created on a powerful cloud hosting platform which runs on the ZFS file system. ZFS uses a compression algorithm called LZ4 that surpasses any other algorithm you will find in terms of speed and data compression ratio when it comes to processing web content. This is valid particularly when data is uncompressed because LZ4 does that much faster than it would be to read uncompressed data from a hard drive and for that reason, sites running on a platform where LZ4 is present will work at a higher speed. We can take advantage of the feature despite of the fact that it needs quite a considerable amount of CPU processing time as our platform uses numerous powerful servers working together and we do not make accounts on just a single machine like the vast majority of companies do. There is another reward of using LZ4 - given that it compresses data really well and does that extremely fast, we can also generate multiple daily backup copies of all accounts without influencing the performance of the servers and keep them for a whole month. By doing this, you can always recover any content that you erase by accident.
