Data compression is the decrease of the number of bits that have to be stored or transmitted and this process is very important in the internet hosting field as data filed on hard disks is usually compressed to take less space. You will find various algorithms for compressing info and they offer different efficiency based on the content. Many of them remove just the redundant bits, so that no data can be lost, while others delete unnecessary bits, which leads to worse quality once your data is uncompressed. The process consumes plenty of processing time, so a hosting server needs to be powerful enough to be able to compress and uncompress data right away. An instance how binary code may be compressed is by "remembering" that there're five consecutive 1s, for example, as an alternative to storing all five 1s.
Data Compression in Web Hosting
The ZFS file system that is run on our cloud web hosting platform employs a compression algorithm named LZ4. The latter is significantly faster and better than any other algorithm available on the market, especially for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data quicker than it is read from a hard disk, which improves the overall performance of websites hosted on ZFS-based platforms. Because the algorithm compresses data quite well and it does that very quickly, we're able to generate several backups of all the content kept in the web hosting accounts on our servers every day. Both your content and its backups will take reduced space and since both ZFS and LZ4 work extremely fast, the backup generation will not change the performance of the web hosting servers where your content will be kept.
Data Compression in Semi-dedicated Servers
If you host your websites in a semi-dedicated server 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 hosting platform. What distinguishes LZ4 from all of the other algorithms out there is that it has a higher compression ratio and it is much quicker, especially with regard to uncompressing website content. It does that even quicker than uncompressed information can be read from a hard disk drive, so your sites will perform better. The higher speed is at the expense of using a lot of CPU processing time, that's not a problem for our platform as it consists of a lot of clusters working together. Besides the superior performance, you will also have multiple daily backups at your disposal, so you will be able to restore any deleted content with a couple of clicks. The backup copies are available for an entire month and we can afford to store them as they take considerably less space compared to standard backups.
