The term data compression refers to lowering the number of bits of information which needs to be stored or transmitted. This can be done with or without the loss of info, which means that what will be erased throughout the compression shall be either redundant data or unnecessary one. When the data is uncompressed subsequently, in the first case the data and its quality shall be the same, whereas in the second case the quality shall be worse. You'll find various compression algorithms that are more effective for different sort of data. Compressing and uncompressing data in most cases takes plenty of processing time, which means that the server executing the action must have adequate resources in order to be able to process the data fast enough. An example how information can be compressed is to store just how many consecutive positions should have 1 and just how many should have 0 within the binary code as an alternative to storing the actual 1s and 0s.
Data Compression in Web Hosting
The ZFS file system that runs on our cloud Internet hosting platform employs a compression algorithm named LZ4. The aforementioned is a lot faster and better than any other algorithm you will find, particularly for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data quicker than it is read from a hard disk, which improves the overall performance of websites hosted on ZFS-based platforms. As the algorithm compresses data quite well and it does that quickly, we're able to generate several backup copies of all the content kept in the web hosting
accounts on our servers every day. Both your content and its backups will need less space and since both ZFS and LZ4 work extremely fast, 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
The ZFS file system that runs on the cloud platform where your semi-dedicated hosting
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 website content, as its ratio is very high and it will uncompress data faster than the same data can be read from a hard disk drive if it were uncompressed. This way, using LZ4 will accelerate any kind of Internet site that runs on a platform where the algorithm is enabled. This high performance requires plenty of CPU processing time, which is provided by the multitude of clusters working together as part of our platform. In addition, LZ4 makes it possible for us to generate several backups of your content every day and have them for one month as they will take a reduced amount of space than standard backups and will be generated considerably quicker without loading the servers.
