The term data compression describes lowering the number of bits of data that needs to be stored or transmitted. This can be done with or without the loss of data, so what will be deleted during 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 the same, whereas in the second case the quality will be worse. You will find various compression algorithms which are better for various type of data. Compressing and uncompressing data normally takes plenty of processing time, which means that the server carrying out the action needs to have adequate resources to be able to process your data quick enough. An example how information can be compressed is to store how many consecutive positions should have 1 and how many should have 0 inside the binary code as an alternative to storing the actual 1s and 0s.
Data Compression in Cloud Hosting
The ZFS file system that operates on our cloud hosting platform uses a compression algorithm identified as LZ4. The aforementioned is considerably faster and better than every other algorithm you will 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 drive, which improves the performance of sites hosted on ZFS-based platforms. Due to the fact that the algorithm compresses data very well and it does that quickly, we're able to generate several backups of all the content stored in the cloud hosting accounts on our servers on a daily basis. Both your content and its backups will require less space and since both ZFS and LZ4 work very fast, the backup generation will not change the performance of the hosting servers where your content will be stored.
Data Compression in Semi-dedicated Hosting
The semi-dedicated hosting plans that we offer are created on a powerful cloud hosting platform which runs on the ZFS file system. ZFS employs a compression algorithm known as LZ4 that is greater than any other algorithm out there in terms of speed and compression ratio when it comes to processing website content. This is valid particularly when data is uncompressed as LZ4 does that much faster than it would be to read uncompressed data from a hard drive and owing to this, Internet sites running on a platform where LZ4 is enabled will function at a higher speed. We are able to take full advantage of the feature despite of the fact that it needs quite a considerable amount of CPU processing time because our platform uses a wide range of powerful servers working together and we never make accounts on a single machine like a lot of companies do. There is a further reward of using LZ4 - since it compresses data really well and does that extremely fast, we can also make several daily backup copies of all accounts without influencing the performance of the servers and keep them for a whole month. That way, you will always be able to restore any content that you delete by accident.
