Data compression is the compacting of data by decreasing the number of bits that are stored or transmitted. In this way, the compressed data will need less disk space than the initial one, so additional content can be stored on identical amount of space. You will find different compression algorithms which work in different ways and with several of them just the redundant bits are deleted, so once the data is uncompressed, there is no loss of quality. Others delete unneeded bits, but uncompressing the data at a later time will result in lower quality compared to the original. Compressing and uncompressing content requires a significant amount of system resources, and in particular CPU processing time, therefore each and every hosting platform that uses compression in real time must have adequate power to support that attribute. An example how information can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" how many sequential 1s or 0s there should be instead of saving the entire code.

Data Compression in Website Hosting

The cloud web hosting platform where your website hosting account is created employs the cutting-edge ZFS file system. The LZ4 compression method which the aforementioned uses is greater in various aspects, and not only does it compress data better than any compression method which some other file systems use, but it is also a lot faster. The gains are significant in particular on compressible content such as website files. Although it could sound unreasonable, uncompressing data with LZ4 is faster than reading uncompressed data from a hard disk drive, so the performance of each site hosted on our servers shall be improved. The better and quicker compression rates also make it possible for us to produce numerous daily backups of the whole content in every single web hosting account, so if you delete anything by accident, the last back-up copy that we have will not be more than several hours old. This is possible because the backups take a lot less space and their generation is quick enough, so as to not change the performance of the servers.

Data Compression in Semi-dedicated Hosting

Your semi-dedicated hosting account will be created on a cloud platform which is run on the innovative ZFS file system. The aforementioned uses a compression algorithm named LZ4, which is a lot better than all other algorithms when it comes to compression ratio and speed. The gain is apparent especially when data is being uncompressed and not only is LZ4 much quicker than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a hard disk. That is why Internet sites running on a platform that uses LZ4 compression perform better because the algorithm is most efficient when it processes compressible data i.e. website content. Another advantage of using LZ4 is that the backup copies of the semi-dedicated accounts which we keep need much less space and they're generated a lot quicker, which allows us to store several daily backups of your files and databases.
