Data compression is the decrease of the number of bits that have to be stored or transmitted and the process is rather important in the internet hosting field due to the fact that information stored on hard drives is usually compressed so as to take less space. There are many different algorithms for compressing info and they have different efficiency based upon the content. A number of them remove just the redundant bits, so no data will be lost, while others remove unneeded bits, which leads to worse quality when your data is uncompressed. The method requires a lot of processing time, so an internet hosting server needs to be powerful enough so as to be able to compress and uncompress data instantly. An instance how binary code may be compressed is by "remembering" that there are five consecutive 1s, for example, in contrast to storing all five 1s.

Data Compression in Hosting

The ZFS file system which is run on our cloud hosting platform uses a compression algorithm identified as LZ4. The aforementioned is considerably faster and better than any other algorithm out there, especially for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data quicker than it is read from a hard drive, which improves the performance of sites hosted on ZFS-based platforms. As the algorithm compresses data really well and it does that quickly, we're able to generate several backups of all the content kept in the hosting accounts on our servers every day. Both your content and its backups will take less space and since both ZFS and LZ4 work very fast, the backup generation will not change the performance of the hosting servers where your content will be stored.

Data Compression in Semi-dedicated Servers

Your semi-dedicated server account shall be created on a cloud platform that runs using the state-of-the-art ZFS file system. The aforementioned uses a compression algorithm known as LZ4, that's significantly better than other algorithms regarding compression ratio and speed. The gain is visible especially when data is being uncompressed and not only is LZ4 much quicker than other algorithms, but it is also faster in uncompressing data than a system is in reading from a hard disk drive. This is why websites running on a platform which employs LZ4 compression perform better because the algorithm is most efficient when it processes compressible data i.e. website content. A further advantage of using LZ4 is that the backups of the semi-dedicated accounts which we keep take a lot less space and they are generated quicker, which enables us to keep several daily backups of all your files and databases.
