The term data compression identifies reducing the number of bits of information which has to be stored or transmitted. You can do this with or without the loss of info, which means that what will be deleted in the course of the compression shall be either redundant data or unneeded one. When the data is uncompressed subsequently, in the first case the content and its quality shall be identical, whereas in the second case the quality will be worse. You'll find different compression algorithms which are more efficient for various sort of data. Compressing and uncompressing data often takes lots of processing time, so the server performing the action should have adequate resources to be able to process your data quick 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 Website Hosting
The ZFS file system that operates on our cloud web hosting platform uses a compression algorithm named LZ4. The aforementioned is a lot faster and better than every other algorithm on the market, especially for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data faster than it is read from a hard disk drive, 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 very fast, we are able to generate several backups of all the content stored in the website hosting accounts on our servers every day. Both your content and its backups will take reduced space and since both ZFS and LZ4 work very fast, the backup generation will not influence the performance of the hosting servers where your content will be kept.
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 positively the most efficient one when it comes to compressing and uncompressing web content, as its ratio is very high and it'll uncompress data at a faster rate than the same data can be read from a hard drive if it were uncompressed. That way, using LZ4 will quicken any kind of site that runs on a platform where this algorithm is enabled. This high performance requires a lot of CPU processing time, that 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 backup copies of your content every day and keep them for a month as they will take a smaller amount of space than standard backups and will be created considerably faster without loading the servers.
