The term data compression describes reducing the number of bits of information which should be stored or transmitted. This can be achieved with or without the loss of data, so what will be deleted at the time of the compression will be either redundant data or unneeded one. When the data is uncompressed afterwards, in the first case the content and its quality will be the same, whereas in the second case the quality shall be worse. There're various compression algorithms that are more efficient for different sort of info. Compressing and uncompressing data often takes lots of processing time, therefore the server carrying out the action needs to have plenty of resources to be able to process your info fast enough. An example how information can be compressed is to store how many consecutive positions should have 1 and just how many should have 0 inside the binary code instead of storing the particular 1s and 0s.

Data Compression in Shared Website Hosting

The ZFS file system which runs on our cloud web hosting platform employs a compression algorithm identified as LZ4. The aforementioned is considerably faster and better than any other algorithm you will find, particularly for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data faster than it is read from a hard drive, which improves the performance of sites hosted on ZFS-based platforms. As the algorithm compresses data very well and it does that quickly, we can generate several backup copies of all the content stored in the shared website hosting accounts on our servers on a daily basis. Both your content and its backups will require reduced space and since both ZFS and LZ4 work very fast, the backup generation will not affect the performance of the web servers where your content will be kept.

Data Compression in Semi-dedicated Hosting

The ZFS file system which 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 positively the most efficient one when it comes to compressing and uncompressing web 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. That way, using LZ4 will accelerate every website that runs on a platform where the algorithm is enabled. 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 to that, LZ4 makes it possible for us to generate several backups of your content every day and keep them for one month as they'll take a reduced amount of space than standard backups and will be generated considerably quicker without loading the servers.
