Data compression is the lowering of the number of bits which need to be saved or transmitted and this process is very important in the internet hosting field because info recorded on HDDs is usually compressed so as to take less space. There are various algorithms for compressing data and they provide different effectiveness based on the content. Many of them remove just the redundant bits, so no data will be lost, while others remove unnecessary bits, which results in worse quality when your data is uncompressed. The method requires plenty of processing time, so an internet hosting server should be powerful enough to be able to compress and uncompress data right away. One example how binary code could be compressed is by "remembering" that there're five consecutive 1s, for example, as an alternative to storing all five 1s.
Data Compression in Shared Website Hosting
The ZFS file system which is run on our cloud web hosting platform uses a compression algorithm named LZ4. The latter is considerably faster and better than every other algorithm out there, particularly 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 websites hosted on ZFS-based platforms. Since the algorithm compresses data quite well and it does that quickly, we are able to generate several backup copies of all the content stored in the shared website 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 quickly, the backup generation will not change the performance of the web hosting servers where your content will be kept.
Data Compression in Semi-dedicated Hosting
The ZFS file system that runs on the cloud platform where your semi-dedicated hosting account will be created uses a powerful compression algorithm called LZ4. It's one of the best algorithms out there and certainly the best one when it comes to compressing and uncompressing web content, as its ratio is very high and it'll uncompress data quicker than the same data can be read from a hard drive if it were uncompressed. In this way, using LZ4 will boost every website that runs on a platform where this algorithm is present. This high performance requires a lot of CPU processing time, which is provided by the great number of clusters working together as part of our platform. In addition, LZ4 allows us to generate several backups of your content every day and keep them for one month as they'll take a smaller amount of space than standard backups and will be created much faster without loading the servers.
