The term data compression describes decreasing the number of bits of data that should be stored or transmitted. This can be achieved with or without losing data, which means that what will be erased during the compression will be either redundant data or unnecessary one. When the data is uncompressed subsequently, in the first case the data and its quality will be identical, while in the second case the quality will be worse. You will find various compression algorithms that are more effective for different sort of data. Compressing and uncompressing data frequently takes a lot of processing time, therefore the server executing the action needs to have ample resources to be able to process your info quick enough. A simple example how information can be compressed is to store just how many sequential positions should have 1 and how many should have 0 within the binary code as an alternative to storing the particular 1s and 0s.
Data Compression in Cloud Hosting
The ZFS file system which operates on our cloud Internet hosting platform employs a compression algorithm identified as LZ4. The latter is a lot 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 quicker than it is read from a hard disk drive, which improves the overall performance of websites hosted on ZFS-based platforms. As 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 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 extremely fast, the backup generation will not affect the performance of the 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 that runs using the state-of-the-art ZFS file system. The aforementioned uses a compression algorithm known as LZ4, which is far better than alternative algorithms with regard to compression ratio and speed. The gain is visible particularly when data is being uncompressed and not only is LZ4 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 why sites running on a platform that uses LZ4 compression perform faster because the algorithm is most efficient when it processes compressible data i.e. site content. A further advantage of using LZ4 is that the backup copies of the semi-dedicated accounts that we keep require significantly less space and they are generated a lot faster, which allows us to have several daily backups of all your files and databases.
