Data compression is the lowering of the number of bits that should be saved or transmitted and the process is very important in the web hosting field due to the fact that data filed on hard disks is often compressed in order to take less space. You will find many different algorithms for compressing info and they have different efficiency based upon the content. A lot of them remove only the redundant bits, so no data can be lost, while others delete unneeded bits, which leads to worse quality once the data is uncompressed. The process uses a lot of processing time, which means that a web hosting server needs to be powerful enough to be able to compress and uncompress data quickly. An instance how binary code could be compressed is by "remembering" that there're five consecutive 1s, for example, rather than storing all five 1s.

Data Compression in Shared Hosting

The cloud internet hosting platform where your shared hosting account shall be created employs the advanced ZFS file system. The LZ4 compression method which the latter employs is greater in numerous aspects, and not only does it compress information better than any compression method which a variety of other file systems use, but it is also much faster. The gains may be significant especially on compressible content like website files. Despite the fact that it could sound unreasonable, uncompressing data with LZ4 is faster than reading uncompressed info from a hard disk drive, so the performance of any site hosted on our servers shall be upgraded. The better and quicker compression rates also make it possible for us to generate numerous daily backups of the entire content in each and every hosting account, so if you delete anything by accident, the last back-up copy which we have will not be more than several hours old. This is possible as the backups take a lot less space and their generation is fast enough, so as to not change the performance of our servers.
