Data compression is the reduction of the number of bits which have to be stored or transmitted and the process is rather important in the internet hosting field since information located on HDDs is typically compressed to take less space. There're many different algorithms for compressing info and they offer different effectiveness depending on the content. A lot of them remove only the redundant bits, so that no data can be lost, while others remove unneeded bits, which leads to worse quality once your data is uncompressed. The method employs a lot of processing time, which means that a web hosting server has to be powerful enough in order to be able to compress and uncompress data instantly. An instance how binary code may be compressed is by "remembering" that there're five consecutive 1s, for example, rather than storing all five 1s.
Data Compression in Web Hosting
The cloud hosting platform where your web hosting account is created uses the reliable ZFS file system. The LZ4 compression method that the aforementioned uses is superior in lots of aspects, and not only does it compress information better than any compression method that similar file systems use, but it's also quicker. The gains may be significant especially on compressible content like website files. Even though it may sound irrational, uncompressing data with LZ4 is faster than reading uncompressed data from a hard disk drive, so the performance of any Internet site hosted on our servers shall be boosted. The better and faster compression rates also make it possible for us to generate numerous daily backups of the full content in every single hosting account, so if you delete anything by accident, the last backup that we have won't be more than several hours old. This is possible as the backups take a lot less space and their generation is quick enough, so as to not influence the performance of our servers.
