Data compression is the compacting of info by reducing the number of bits that are stored or transmitted. This way, the compressed info requires substantially less disk space than the original one, so additional content might be stored using the same amount of space. There're various compression algorithms that work in different ways and with a number of them only the redundant bits are removed, so once the info is uncompressed, there is no decrease in quality. Others remove excessive bits, but uncompressing the data afterwards will lead to reduced quality compared to the original. Compressing and uncompressing content needs a significant amount of system resources, especially CPU processing time, so every Internet hosting platform that employs compression in real time must have adequate power to support that attribute. An example how information can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" the number of consecutive 1s or 0s there should be instead of saving the entire code.

Data Compression in Hosting

The compression algorithm which we work with on the cloud internet hosting platform where your new hosting account shall be created is called LZ4 and it is used by the advanced ZFS file system which powers the platform. The algorithm is better than the ones other file systems employ as its compression ratio is a lot higher and it processes data a lot quicker. The speed is most noticeable when content is being uncompressed as this happens at a faster rate than data can be read from a hard disk. For that reason, LZ4 improves the performance of each Internet site hosted on a server which uses this algorithm. We take full advantage of LZ4 in one more way - its speed and compression ratio make it possible for us to generate multiple daily backup copies of the full content of all accounts and store them for 30 days. Not only do our backup copies take less space, but in addition their generation doesn't slow the servers down like it often happens with other file systems.

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 uses a compression algorithm named LZ4 that is better than any other algorithm out there in terms of speed and compression ratio when it comes to processing website 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 and as a result, Internet sites running on a platform where LZ4 is enabled will work quicker. We can benefit from the feature despite of the fact that it requires quite a lot of CPU processing time as our platform uses a wide range of powerful servers working together and we never make accounts on just a single machine like a lot of companies do. There is a further advantage of using LZ4 - given that it compresses data really well and does that very fast, we can also generate multiple daily backups of all accounts without influencing the performance of the servers and keep them for a whole month. In this way, you will always be able to recover any content that you delete by mistake.
