Data compression is the compacting of info by decreasing the number of bits that are stored or transmitted. As a result, the compressed info requires much less disk space than the original one, so much more content might be stored on the same amount of space. There are many different compression algorithms which function in different ways and with a number of them just the redundant bits are removed, so once the information is uncompressed, there is no loss of quality. Others delete unneeded bits, but uncompressing the data subsequently will result in lower quality compared to the original. Compressing and uncompressing content consumes a large amount of system resources, and in particular CPU processing time, therefore each and every web hosting platform that uses compression in real time needs to have adequate power to support that feature. An example how information can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" the number of consecutive 1s or 0s there should be instead of keeping the actual code.

Data Compression in Shared Hosting

The ZFS file system that is run on our cloud hosting platform employs a compression algorithm named LZ4. The aforementioned is a lot faster and better than every other algorithm on the market, especially for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data faster than it is read from a hard drive, which improves the performance of sites hosted on ZFS-based platforms. Since the algorithm compresses data quite well and it does that very fast, we are able to generate several backups of all the content stored in the shared hosting accounts on our servers every day. Both your content and its backups will require less space and since both ZFS and LZ4 work very quickly, the backup generation will not affect the performance of the web hosting servers where your content will be kept.

Data Compression in Semi-dedicated Servers

In case you host your Internet sites in a semi-dedicated server account with our firm, you can experience the advantages of LZ4 - the powerful compression algorithm employed by the ZFS file system that's behind our advanced cloud hosting platform. What distinguishes LZ4 from all the other algorithms out there is that it has a better compression ratio and it is much quicker, particularly when it comes to uncompressing web content. It does that even faster than uncompressed data can be read from a hard drive, so your websites will perform better. The higher speed comes at the expense of using lots of CPU processing time, that is not an issue for our platform as it consists of a large number of clusters working together. Besides the improved performance, you'll also have multiple daily backups at your disposal, so you'll be able to restore any deleted content with just a few clicks. The backup copies are available for a whole month and we can afford to keep them because they take a lot less space compared to traditional backups.
