Data compression is the decrease of the number of bits which have to be stored or transmitted and the process is quite important in the web hosting field because info kept on hard disk drives is generally compressed so as to take less space. There're many different algorithms for compressing information and they have different efficiency depending on the content. Many of them remove only the redundant bits, so that no data will be lost, while others delete unneeded bits, which leads to worse quality when your data is uncompressed. This process employs a lot of processing time, so an internet 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 are five sequential 1s, for example, in contrast to storing all five 1s.
Data Compression in Cloud Hosting
The ZFS file system which is run on our cloud web hosting platform uses a compression algorithm identified as LZ4. The latter is significantly faster and better than every other algorithm out there, particularly for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data faster than it is read from a hard disk, which improves the overall performance of sites hosted on ZFS-based platforms. As the algorithm compresses data really well and it does that very quickly, we can generate several backup copies of all the content stored in the cloud hosting accounts on our servers every day. Both your content and its backups will take reduced space and since both ZFS and LZ4 work very quickly, the backup generation will not change the performance of the web servers where your content will be stored.
Data Compression in Semi-dedicated Servers
If you host your sites in a semi-dedicated server account from our firm, you will be able to experience the advantages of LZ4 - the powerful compression algorithm used by the ZFS file system that is behind our advanced cloud hosting platform. What separates LZ4 from all of the other algorithms out there is that it has an improved compression ratio and it is much quicker, particularly with regard to uncompressing website content. It does that even quicker than uncompressed information can be read from a hard drive, so your websites will perform faster. The higher speed is at the expense of using a considerable amount of CPU processing time, which is not an issue for our platform since it consists of numerous clusters working together. Along with the better performance, you'll also have multiple daily backups at your disposal, so you'll be able to recover any deleted content with just a few clicks. The backups are available for a whole month and we can afford to keep them because they need considerably less space than ordinary backups.
