Data compression is the compacting of data by reducing the number of bits which are stored or transmitted. Thus, the compressed data will require substantially less disk space than the initial one, so much more content might be stored using the same amount of space. There're various compression algorithms which work in different ways and with several of them only the redundant bits are deleted, so once the data is uncompressed, there's no loss of quality. Others erase unnecessary bits, but uncompressing the data afterwards will lead to reduced quality compared to the original. Compressing and uncompressing content consumes a huge amount of system resources, especially CPU processing time, therefore every hosting platform that employs compression in real time must have ample power to support this attribute. An example how info can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" what number of consecutive 1s or 0s there should be instead of saving the actual code.
Data Compression in Shared Website Hosting
The compression algorithm which we employ on the cloud web hosting platform where your new shared website hosting account shall be created is known as LZ4 and it's applied by the revolutionary ZFS file system which powers the system. The algorithm is far better than the ones other file systems use because its compression ratio is higher and it processes data considerably quicker. The speed is most noticeable when content is being uncompressed as this happens more quickly than data can be read from a hard drive. Consequently, LZ4 improves the performance of every website located on a server which uses the algorithm. We use LZ4 in one more way - its speed and compression ratio let us generate several daily backups of the full content of all accounts and store them for 30 days. Not only do our backup copies take less space, but in addition their generation will not slow the servers down like it can often happen with many other file systems.
Data Compression in Semi-dedicated Servers
In case you host your websites in a semi-dedicated server account with our company, 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 web hosting platform. What separates LZ4 from all other algorithms out there is that it has an improved compression ratio and it is much quicker, particularly when it comes to uncompressing web content. It does that even quicker than uncompressed information can be read from a hard drive, so your Internet sites will perform better. The higher speed comes at the expense of using plenty of CPU processing time, that's not an issue for our platform because it consists of a lot of clusters working together. Along with the superior performance, you'll also have multiple daily backup copies at your disposal, so you could recover any deleted content with a few clicks. The backups are available for a whole month and we can afford to keep them as they take a lot less space compared to ordinary backups.
