The term data compression refers to decreasing the number of bits of data that should be saved or transmitted. This can be done with or without the loss of data, so what will be deleted at the time of the compression will be either redundant data or unnecessary one. When the data is uncompressed afterwards, in the first case the data and the quality will be the same, while in the second case the quality shall be worse. There are various compression algorithms which are more efficient for various kind of information. Compressing and uncompressing data usually takes plenty of processing time, so the server executing the action should have ample resources in order to be able to process your info fast enough. One simple example how information can be compressed is to store how many sequential positions should have 1 and how many should have 0 within the binary code rather than storing the particular 1s and 0s.
Data Compression in Cloud Hosting
The ZFS file system which runs on our cloud hosting platform uses a compression algorithm called LZ4. The latter is significantly faster and better than every other algorithm you will find, especially for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data quicker than it is read from a hard drive, which improves the overall performance of websites hosted on ZFS-based platforms. Due to the fact that the algorithm compresses data really well and it does that quickly, we are able to 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 need less space and since both ZFS and LZ4 work very quickly, the backup generation will not affect the performance of the web hosting servers where your content will be kept.
Data Compression in Semi-dedicated Servers
The ZFS file system which 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 certainly the most efficient one when it comes to compressing and uncompressing website content, as its ratio is very high and it will uncompress data quicker than the same data can be read from a hard disk drive if it were uncompressed. Thus, using LZ4 will accelerate every website that runs on a platform where the algorithm is present. This high performance requires lots of CPU processing time, that's provided by the numerous clusters working together as part of our platform. In addition, LZ4 makes it possible for us to generate several backup copies of your content every day and keep them for one month as they'll take a smaller amount of space than regular backups and will be created much quicker without loading the servers.
