The term data compression means reducing the number of bits of information which needs to be stored or transmitted. This can be done with or without the loss of data, which means that what will be removed at the time of the compression will be either redundant data or unnecessary one. When the data is uncompressed later on, in the first case the content and its quality shall be the same, whereas in the second case the quality shall be worse. There're various compression algorithms that are more efficient for various sort of data. Compressing and uncompressing data generally takes a lot of processing time, which means that the server carrying out the action should have plenty of resources in order to be able to process the 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 inside the binary code rather than storing the particular 1s and 0s.

Data Compression in Shared Website Hosting

The cloud internet hosting platform where your shared website hosting account is made works by using the innovative ZFS file system. The LZ4 compression method that the latter uses is greater in many aspects, and not only does it compress info better than any compression method that a number of other file systems use, but it's also quicker. The gains can be significant especially on compressible content which includes website files. While it may sound illogical, uncompressing data with LZ4 is faster than reading uncompressed info from a hard disk, so the performance of every Internet site hosted on our servers shall be upgraded. The better and faster compression rates also make it possible for us to generate multiple daily backups of the entire content in each web hosting account, so should you delete something by mistake, the last backup which we have will not be more than a few hours old. This can be done as the backups take a lot less space and their generation is fast enough, to not influence the performance of the servers.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting plans that we offer are created on a powerful cloud platform that runs on the ZFS file system. ZFS uses a compression algorithm named LZ4 that is better than any other algorithm available in terms of speed and data compression ratio when it comes to processing web content. This is valid particularly when data is uncompressed since LZ4 does that faster than it would be to read uncompressed data from a hard disk and because of this, sites running on a platform where LZ4 is present will work quicker. We're able to take advantage of the feature although it requires quite a great deal of CPU processing time as our platform uses a lot of powerful servers working together and we do not make accounts on just a single machine like many companies do. There's another benefit of using LZ4 - given that it compresses data really well and does that speedily, we can also generate multiple daily backups of all accounts without influencing the performance of the servers and keep them for a whole month. This way, you'll always be able to bring back any content that you erase by accident.
