Data compression is the compacting of information by decreasing the number of bits that are stored or transmitted. This way, the compressed information will require substantially less disk space than the initial one, so a lot more content might be stored using identical amount of space. You will find different compression algorithms that work in different ways and with many of them only the redundant bits are erased, therefore once the data is uncompressed, there's no decrease in quality. Others remove unnecessary bits, but uncompressing the data later will result in reduced quality in comparison with the original. Compressing and uncompressing content needs a significant amount of system resources, especially CPU processing time, so each and every hosting platform which uses compression in real time should have ample power to support this feature. An example how information can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" how many sequential 1s or 0s there should be instead of keeping the entire code.

Data Compression in Cloud Hosting

The compression algorithm which we employ on the cloud hosting platform where your new cloud hosting account will be created is known as LZ4 and it's used by the exceptional ZFS file system that powers the system. The algorithm is a lot better than the ones other file systems employ because its compression ratio is a lot higher and it processes data significantly faster. The speed is most noticeable when content is being uncompressed as this happens more quickly than info can be read from a hard disk. Because of this, LZ4 improves the performance of each site stored on a server which uses this particular algorithm. We use LZ4 in an additional way - its speed and compression ratio make it possible for us to produce several daily backup copies of the entire content of all accounts and store them for 30 days. Not only do these backups take less space, but their generation does not slow the servers down like it can often happen with some other file systems.

Data Compression in Semi-dedicated Servers

The semi-dedicated server plans that we offer are created on a powerful cloud platform that 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 website content. This is valid especially when data is uncompressed because LZ4 does that more rapidly than it would be to read uncompressed data from a hard drive and owing to this, websites running on a platform where LZ4 is enabled will function faster. We are able to take advantage of the feature regardless of the fact that it needs quite a considerable amount of CPU processing time as our platform uses many powerful servers working together and we don't make accounts on just a single machine like the vast majority of companies do. There's another benefit of using LZ4 - since it compresses data very well and does that speedily, we can also generate multiple daily backup copies of all accounts without influencing the performance of the servers and keep them for an entire month. In this way, you will always be able to bring back any content that you erase by mistake.
