The term data compression refers to lowering the number of bits of information that needs to be stored or transmitted. You can do this with or without losing data, so what will be deleted at the time of the compression can be either redundant data or unneeded one. When the data is uncompressed later on, in the first case the data and its quality will be the same, whereas in the second case the quality will be worse. There are different compression algorithms that are more effective for different sort of information. Compressing and uncompressing data often takes plenty of processing time, therefore the server carrying out the action must have adequate resources to be able to process the data quick enough. An example how information can be compressed is to store just how many sequential positions should have 1 and just how many should have 0 inside the binary code instead of storing the actual 1s and 0s.

Data Compression in Shared Hosting

The compression algorithm that we employ on the cloud internet hosting platform where your new shared hosting account shall be created is named LZ4 and it's applied by the cutting-edge ZFS file system which powers the system. The algorithm is a lot better than the ones other file systems employ since its compression ratio is a lot higher and it processes data considerably faster. The speed is most noticeable when content is being uncompressed as this happens more quickly than info can be read from a hard disk drive. For that reason, LZ4 improves the performance of each site located on a server that uses this particular algorithm. We take full advantage of LZ4 in an additional way - its speed and compression ratio make it possible for us to produce several daily backup copies of the whole content of all accounts and keep them for thirty days. Not only do our backups take less space, but in addition their generation will not slow the servers down like it often happens with other file systems.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting plans which we provide are created on a powerful cloud hosting platform that runs on the ZFS file system. ZFS employs a compression algorithm called LZ4 that outperforms any other algorithm available in terms of speed and compression ratio when it comes to processing web content. This is valid particularly when data is uncompressed as LZ4 does that a lot faster than it would be to read uncompressed data from a hard disk drive and because of this, Internet sites running on a platform where LZ4 is enabled will function faster. We're able to take advantage of the feature regardless of the fact that it requires quite a large amount of CPU processing time as our platform uses a lot of powerful servers working together and we do not create accounts on a single machine like a lot of companies do. There's an additional advantage of using LZ4 - considering the fact that it compresses data rather well and does that speedily, we can also generate several daily backups of all accounts without influencing the performance of the servers and keep them for 30 days. By doing this, you will always be able to recover any content that you erase by mistake.
