The term data compression refers to lowering the number of bits of info that has to be saved or transmitted. This can be done with or without the loss of data, which means that what will be deleted at the time of the compression will be either redundant data or unnecessary one. When the data is uncompressed later on, in the first case the data and the quality will be the same, whereas in the second case the quality will be worse. You'll find different compression algorithms which are more efficient for various kind of information. Compressing and uncompressing data frequently takes a lot of processing time, therefore the server carrying out the action needs to have adequate resources in order to be able to process your data fast enough. A simple example how information can be compressed is to store just how many consecutive positions should have 1 and how many should have 0 inside the binary code rather than storing the actual 1s and 0s.

Data Compression in Cloud Hosting

The compression algorithm used by the ZFS file system which runs on our cloud web hosting platform is known as LZ4. It can upgrade the performance of any website hosted in a cloud hosting account with us as not only does it compress data more efficiently than algorithms used by other file systems, but it also uncompresses data at speeds that are higher than the hard disk reading speeds. This can be done by using a great deal of CPU processing time, that is not a problem for our platform because it uses clusters of powerful servers working together. A further advantage of LZ4 is that it allows us to generate backups much quicker and on reduced disk space, so we will have multiple daily backups of your files and databases and their generation will not influence the performance of the servers. This way, we could always recover any content that you may have removed by accident.

Data Compression in Semi-dedicated Servers

The semi-dedicated server plans that we supply are created on a powerful cloud platform that runs on the ZFS file system. ZFS works with a compression algorithm called LZ4 that is greater than any other algorithm available in terms of speed and data compression ratio when it comes to processing web content. This is valid especially when data is uncompressed since LZ4 does that a lot faster than it would be to read uncompressed data from a hard disk and as a result, sites running on a platform where LZ4 is enabled will work quicker. We are able to benefit from this feature despite of the fact that it needs quite a considerable amount of CPU processing time because our platform uses many powerful servers working together and we don't make accounts on just a single machine like the majority of companies do. There is one more advantage of using LZ4 - considering that it compresses data rather well and does that very quickly, we can also generate several daily backups of all accounts without influencing the performance of the servers and keep them for an entire month. In this way, you will always be able to recover any content that you erase by accident.
