The term data compression refers to decreasing the number of bits of information that has to be stored or transmitted. You can do this with or without the loss of information, so what will be erased throughout the compression will be either redundant data or unneeded one. When the data is uncompressed afterwards, in the first case the info and its quality will be identical, while in the second case the quality will be worse. You can find various compression algorithms that are more efficient for various kind of info. Compressing and uncompressing data normally takes a lot of processing time, so the server performing the action must have sufficient resources to be able to process the info quick enough. A simple example how information can be compressed is to store how many consecutive positions should have 1 and how many should have 0 in the binary code instead of storing the actual 1s and 0s.

Data Compression in Cloud Website Hosting

The cloud internet hosting platform where your cloud website hosting account shall be made employs the outstanding ZFS file system. The LZ4 compression method which the aforementioned uses is greater in various aspects, and not only does it compress information better than any compression method which similar file systems use, but it's also faster. The gains may be significant especially on compressible content such as website files. While it could sound irrational, uncompressing data with LZ4 is faster than reading uncompressed info from a hard disk, so the performance of each and every Internet site hosted on our servers will be better. The better and faster compression rates also allow us to produce a large number of daily backups of the full content in each web hosting account, so in the event you delete something by accident, the last backup which we have will not be more than a couple of hours old. This is possible as the backups take a lot less space and their generation is fast enough, so as to not affect 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 which runs on the ZFS file system. ZFS uses a compression algorithm known as LZ4 that is better than any other algorithm available on the market in terms of speed and data compression ratio when it comes to processing web content. This is valid especially when data is uncompressed since LZ4 does that more rapidly than it would be to read uncompressed data from a hard disk drive and as a result, websites running on a platform where LZ4 is present will work at a higher speed. We can take advantage of this feature although it requires quite a large amount of CPU processing time because our platform uses numerous powerful servers working together and we do not make accounts on just a single machine like the vast majority of companies do. There's an additional reward of using LZ4 - since it compresses data rather well and does that very quickly, we can also generate multiple daily backup copies of all accounts without affecting the performance of the servers and keep them for 30 days. This way, you'll always be able to recover any content that you delete by mistake.
