Data compression is the lowering of the number of bits that should be stored or transmitted and this particular process is rather important in the web hosting field as information located on hard disk drives is generally compressed so as to take less space. There are different algorithms for compressing data and they provide different efficiency based on the content. A number of them remove only the redundant bits, so that no data can be lost, while others remove unnecessary bits, which results in worse quality once the data is uncompressed. The process employs a lot of processing time, therefore a hosting server should be powerful enough to be able to compress and uncompress data in real time. An instance how binary code can be compressed is by "remembering" that there're five consecutive 1s, for example, rather than storing all five 1s.

Data Compression in Website Hosting

The compression algorithm which we use on the cloud internet hosting platform where your new website hosting account shall be created is known as LZ4 and it's used by the revolutionary ZFS file system that powers the platform. The algorithm is much better than the ones other file systems use as its compression ratio is much higher and it processes data considerably quicker. The speed is most noticeable when content is being uncompressed as this happens at a faster rate than information can be read from a hard drive. For that reason, LZ4 improves the performance of each and every website located on a server that uses this particular algorithm. We use LZ4 in one more way - its speed and compression ratio make it possible for us to make multiple daily backups of the full content of all accounts and keep them for one month. Not only do the backups take less space, but also their generation doesn't slow the servers down like it often happens with various other file systems.
