The term data compression identifies reducing the number of bits of information that needs to be stored or transmitted. You can do this with or without losing info, so what will be deleted in the course of the compression can be either redundant data or unneeded one. When the data is uncompressed subsequently, in the first case the information and the quality shall be the same, whereas in the second case the quality shall be worse. You can find various compression algorithms that are more effective for various sort of information. Compressing and uncompressing data frequently takes lots of processing time, which means that the server performing the action must have enough resources to be able to process your data quick enough. One simple example how information can be compressed is to store just how many sequential positions should have 1 and how many should have 0 within the binary code instead of storing the actual 1s and 0s.

Data Compression in Hosting

The cloud hosting platform where your hosting account is made works by using the revolutionary ZFS file system. The LZ4 compression method which the aforementioned uses is superior in many aspects, and not only does it compress data better than any compression method that some other file systems use, but it's also much quicker. The gains can be significant particularly on compressible content like website files. Even though it may sound irrational, uncompressing data with LZ4 is quicker than reading uncompressed info from a hard disk, so the performance of each and every website hosted on our servers will be boosted. The better and quicker compression rates also make it possible for us to produce a number of daily backups of the entire content in each and every web hosting account, so in the event you delete anything by mistake, the last backup which we have won't be more than several hours old. This can be done because the backups take considerably less space and their generation is quick enough, so as to not change the performance of the servers.

Data Compression in Semi-dedicated Servers

The semi-dedicated server plans which we provide are created on a powerful cloud platform which runs on the ZFS file system. ZFS employs a compression algorithm named LZ4 that exceeds any other algorithm available on the market in terms of speed and data compression ratio when it comes to processing website content. This is valid particularly when data is uncompressed as LZ4 does that quicker than it would be to read uncompressed data from a hard disk drive and for that reason, websites running on a platform where LZ4 is present will function faster. We can benefit from this feature although it needs quite a large amount of CPU processing time as our platform uses a number of powerful servers working together and we do not create accounts on a single machine like most companies do. There is an additional benefit of using LZ4 - considering the fact that it compresses data very well and does that very quickly, we can also generate several daily backup copies of all accounts without affecting the performance of the servers and keep them for an entire month. In this way, you will always be able to restore any content that you delete by accident.
