Data compression is the decrease of the number of bits that need to be saved or transmitted and the process is really important in the web hosting field because data recorded on hard disk drives is often compressed in order to take less space. There are different algorithms for compressing information and they provide different efficiency depending on the content. A number of them remove only the redundant bits, so that no data will be lost, while others erase unnecessary bits, which leads to worse quality once your data is uncompressed. The process requires a lot of processing time, therefore a web hosting server has to be powerful enough to be able to compress and uncompress data instantly. An example how binary code could be compressed is by "remembering" that there are five sequential 1s, for example, in contrast to storing all five 1s.
Data Compression in Shared Website Hosting
The ZFS file system which operates on our cloud Internet 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 performance of sites hosted on ZFS-based platforms. Since the algorithm compresses data really well and it does that very quickly, we are able to generate several backups of all the content kept in the shared website hosting accounts on our servers every day. Both your content and its backups will need less space and since both ZFS and LZ4 work very fast, the backup generation will not affect the performance of the web servers where your content will be stored.
Data Compression in Semi-dedicated Hosting
In case you host your websites in a semi-dedicated hosting account from our firm, you can experience the advantages of LZ4 - the powerful compression algorithm used by the ZFS file system that's behind our advanced cloud web hosting platform. What differentiates LZ4 from all other algorithms out there is that it has an improved compression ratio and it is much quicker, especially when it comes to uncompressing web content. It does that even quicker than uncompressed information can be read from a hard drive, so your websites will perform better. The higher speed comes at the expense of using lots of CPU processing time, that is not a problem for our platform since it consists of a lot of clusters working together. Along with the superior performance, you'll have multiple daily backups at your disposal, so you could restore any deleted content with a few clicks. The backup copies are available for a whole month and we can afford to store them as they take significantly less space compared to traditional backups.
