The term data compression means decreasing the number of bits of data that has to be stored or transmitted. This can be done with or without losing information, which means that what will be deleted throughout the compression shall be either redundant data or unneeded one. When the data is uncompressed later on, in the first case the information and its quality shall be the same, whereas in the second case the quality shall be worse. You can find various compression algorithms that are better for various type of data. Compressing and uncompressing data often 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. One simple example how information can be compressed is to store how many sequential positions should have 1 and how many should have 0 inside the binary code as an alternative to storing the actual 1s and 0s.
Data Compression in Shared Website Hosting
The cloud hosting platform where your shared website hosting account is generated employs the outstanding ZFS file system. The LZ4 compression method that the aforementioned employs is superior in various aspects, and not only does it compress data better than any compression method that a variety of other file systems use, but it is also much quicker. The benefits can be significant in particular on compressible content which includes website files. Despite the fact that it could sound unreasonable, uncompressing data with LZ4 is faster than reading uncompressed data from a hard disk, so the performance of each website hosted on our servers shall be boosted. The better and faster compression rates also allow us to generate a large number of daily backups of the entire content in each and every hosting account, so should you delete anything by accident, the last backup which we have will not be more than a few hours old. This can be done as the backups take considerably less space and their generation is quick enough, so as to not affect the performance of our servers.
Data Compression in Semi-dedicated Hosting
The semi-dedicated hosting plans which we provide are created on a powerful cloud platform that runs on the ZFS file system. ZFS works with a compression algorithm named LZ4 that is better than any other algorithm on the market in terms of speed and data 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 as a result, Internet sites running on a platform where LZ4 is enabled will work faster. We are able to benefit from this feature despite of the fact that it requires quite a considerable amount of CPU processing time because our platform uses a wide range of powerful servers working together and we do not create accounts on a single machine like the vast majority of companies do. There's one more advantage of using LZ4 - given that it compresses data rather well and does that very fast, we can also generate several daily backups of all accounts without affecting the performance of the servers and keep them for 30 days. By doing this, you'll always be able to restore any content that you delete by accident.
