The term data compression means lowering the number of bits of information that needs to be stored or transmitted. This can be done with or without the loss of information, so what will be erased in the course of the compression can be either redundant data or unneeded one. When the data is uncompressed afterwards, in the first case the content and its quality will be identical, while in the second case the quality will be worse. You'll find various compression algorithms that are better for different type of information. Compressing and uncompressing data in most cases takes a lot of processing time, therefore the server executing the action should have adequate resources to be able to process your data quick enough. A simple example how information can be compressed is to store how many consecutive positions should have 1 and just how many should have 0 inside the binary code instead of storing the particular 1s and 0s.

Data Compression in Cloud Web Hosting

The cloud hosting platform where your cloud web hosting account is generated employs the impressive ZFS file system. The LZ4 compression method which the latter employs is greater in numerous aspects, and not only does it compress data better than any compression method which some other file systems use, but it is also a lot quicker. The benefits may be significant particularly on compressible content such as website files. Even though it may sound illogical, uncompressing data with LZ4 is quicker than reading uncompressed info from a hard disk drive, so the performance of every website hosted on our servers will be enhanced. The better and faster compression rates also allow us to produce a number of daily backups of the full content in each hosting account, so in the event you delete something by mistake, the last backup that we have won't be more than a couple of hours old. This can be done as the backups take much less space and their generation is quick enough, to not affect the performance of the servers.

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 uses a compression algorithm known as LZ4 that outperforms any other algorithm these days in terms of speed and compression ratio when it comes to processing web content. This is valid particularly when data is uncompressed because LZ4 does that much faster than it would be to read uncompressed data from a hard disk and for that reason, Internet sites running on a platform where LZ4 is present will function quicker. We're able to take advantage of the feature despite of the fact that it needs quite a great deal of CPU processing time because our platform uses many powerful servers working together and we do not make accounts on a single machine like most companies do. There's one more benefit of using LZ4 - considering the fact that it compresses data very well and does that speedily, we can also make multiple daily backup copies of all accounts without affecting the performance of the servers and keep them for a whole month. By doing this, you'll always be able to bring back any content that you erase by mistake.
