The term data compression describes lowering the number of bits of information that needs to be stored or transmitted. This can be done with or without losing data, which means that what will be erased at the time of the compression shall be either redundant data or unnecessary one. When the data is uncompressed subsequently, in the first case the content and its quality shall be identical, while in the second case the quality will be worse. You'll find various compression algorithms which are better for various type of information. Compressing and uncompressing data generally takes a lot of processing time, which means that the server executing the action must have adequate resources in order to be able to process the info quick enough. One simple example how information can be compressed is to store how many sequential positions should have 1 and just how many should have 0 within the binary code instead of storing the particular 1s and 0s.

Data Compression in Cloud Hosting

The ZFS file system that runs on our cloud hosting platform uses a compression algorithm named LZ4. The latter is considerably faster and better than every other algorithm you can 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 overall performance of Internet sites hosted on ZFS-based platforms. As the algorithm compresses data really well and it does that very quickly, we can generate several backups of all the content kept in the cloud 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 quickly, the backup generation will not change the performance of the hosting servers where your content will be stored.

Data Compression in Semi-dedicated Servers

The semi-dedicated server plans that we supply are created on a powerful cloud hosting platform that runs on the ZFS file system. ZFS works with a compression algorithm known as LZ4 that exceeds any other algorithm you can find in terms of speed and data compression ratio when it comes to processing web content. This is valid particularly when data is uncompressed because LZ4 does that more rapidly 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 function faster. We are able to benefit from the feature although it needs quite a great deal of CPU processing time as our platform uses a wide range of powerful servers working together and we do not create accounts on just a single machine like most companies do. There is a further reward of using LZ4 - since it compresses data very well and does that very quickly, we can also make multiple daily backups of all accounts without affecting the performance of the servers and keep them for a month. In this way, you'll always be able to recover any content that you delete by mistake.
