The term data compression means reducing the number of bits of information which needs to be stored or transmitted. This can be achieved with or without the loss of info, so what will be erased at the time of the compression can be either redundant data or unnecessary one. When the data is uncompressed afterwards, in the first case the data and its quality shall be the same, while in the second case the quality shall be worse. You can find different compression algorithms that are better for different sort of info. Compressing and uncompressing data often takes lots of processing time, so the server carrying out the action needs to have plenty of resources to be able to process your data quick enough. An example how information can be compressed is to store how many sequential 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 Cloud Website Hosting

The ZFS file system that is run on our cloud Internet hosting platform uses a compression algorithm identified as LZ4. The aforementioned is considerably faster and better than every other algorithm you can find, particularly for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data faster than it is read from a hard disk, which improves the performance of Internet sites hosted on ZFS-based platforms. Due to the fact that the algorithm compresses data really well and it does that quickly, we're able to generate several backups of all the content stored in the cloud website hosting accounts on our servers daily. Both your content and its backups will take less space and since both ZFS and LZ4 work extremely fast, the backup generation will not affect the performance of the web servers where your content will be kept.

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's among the best algorithms out there and positively the best one when it comes to compressing and uncompressing web content, as its ratio is very high and it will uncompress data at a higher speed than the same data can be read from a hard disk drive if it were uncompressed. That way, using LZ4 will accelerate any kind of site that runs on a platform where this algorithm is enabled. This high performance requires lots of CPU processing time, that's provided by the great number of clusters working together as a part of our platform. What's more, LZ4 allows us to generate several backups of your content every day and keep them for a month as they will take a reduced amount of space than typical backups and will be generated considerably faster without loading the servers.
