The term data compression identifies lowering the number of bits of info which has to be stored or transmitted. This can be achieved with or without the loss of data, which means that what will be erased at the time of the compression shall be either redundant data or unnecessary one. When the data is uncompressed later on, in the first case the information and the quality shall be identical, whereas in the second case the quality shall be worse. There're different compression algorithms that are more effective for various type of info. Compressing and uncompressing data often takes a lot of processing time, so the server executing the action should have adequate resources to be able to process the info fast enough. A simple example how information can be compressed is to store just how many consecutive positions should have 1 and just how many should have 0 in the binary code instead of storing the actual 1s and 0s.

Data Compression in Hosting

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

Data Compression in Semi-dedicated Servers

The ZFS file system that runs on the cloud platform where your semi-dedicated server account will be created uses a powerful compression algorithm called LZ4. It is among the best algorithms out there and definitely the most efficient one when it comes to compressing and uncompressing web content, as its ratio is very high and it'll uncompress data much faster than the same data can be read from a hard drive if it were uncompressed. That way, using LZ4 will speed up every site that runs on a platform where this algorithm is present. The high performance requires a lot of CPU processing time, which is provided by the numerous clusters working together as part of our platform. In addition, LZ4 allows us to generate several backups of your content every day and have them for a month as they will take much less space than regular backups and will be created much faster without loading the servers.
