The term data compression refers to lowering the number of bits of data that has to be stored or transmitted. This can be achieved with or without losing info, so what will be removed throughout the compression can be either redundant data or unneeded one. When the data is uncompressed later on, in the first case the data and the quality shall be identical, whereas in the second case the quality will be worse. You can find different compression algorithms that are better for different sort of data. Compressing and uncompressing data frequently takes a lot of processing time, therefore the server carrying out the action must have sufficient resources to be able to process your data fast enough. A simple example how information can be compressed is to store just how many sequential positions should have 1 and just how many should have 0 in the binary code as an alternative to storing the actual 1s and 0s.
Data Compression in Cloud Hosting
The compression algorithm which we use on the cloud hosting platform where your new cloud hosting account shall be created is called LZ4 and it's used by the revolutionary ZFS file system that powers the platform. The algorithm is greater than the ones other file systems work with because its compression ratio is a lot higher and it processes data a lot faster. The speed is most noticeable when content is being uncompressed as this happens even faster than data can be read from a hard drive. Because of this, LZ4 improves the performance of each Internet site hosted on a server which uses this particular algorithm. We take full advantage of LZ4 in an additional way - its speed and compression ratio allow us to generate a couple of daily backup copies of the full content of all accounts and keep them for a month. Not only do the backups take less space, but their generation doesn't slow the servers down like it can often happen with some other file systems.
