Data compression is the compacting of information by reducing the number of bits which are stored or transmitted. As a result, the compressed data takes substantially less disk space than the original one, so more content could be stored on identical amount of space. There are different compression algorithms that function in different ways and with a lot of them just the redundant bits are erased, which means that once the info is uncompressed, there's no loss of quality. Others remove unnecessary bits, but uncompressing the data afterwards will lead to reduced quality compared to the original. Compressing and uncompressing content needs a huge amount of system resources, in particular CPU processing time, so every web hosting platform that uses compression in real time needs to have adequate power to support that attribute. An example how data can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" what number of sequential 1s or 0s there should be instead of saving the whole code.

Data Compression in Cloud Hosting

The ZFS file system which operates 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, especially for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data quicker than it is read from a hard disk, which improves the performance of sites hosted on ZFS-based platforms. Due to the fact that the algorithm compresses data quite well and it does that very quickly, we can generate several backup copies of all the content kept 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 hosting servers where your content will be stored.

Data Compression in Semi-dedicated Hosting

Your semi-dedicated hosting account shall be created on a cloud platform which is run on the cutting-edge ZFS file system. The latter uses a compression algorithm known as LZ4, that is far better than all the other algorithms in terms of compression ratio and speed. The gain is noticeable 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 drive. This is the reason why Internet sites running on a platform which employs LZ4 compression perform better since the algorithm is most effective when it processes compressible data i.e. web content. A further advantage of using LZ4 is that the backups of the semi-dedicated accounts that we keep take a lot less space and they are generated faster, which allows us to store a number of daily backups of all your files and databases.
