Data compression is the compacting of data by decreasing the number of bits which are stored or transmitted. Because of this, the compressed data takes considerably less disk space than the original one, so a lot more content could be stored using identical amount of space. You'll find many different compression algorithms which work in different ways and with some of them only the redundant bits are erased, therefore once the information is uncompressed, there's no decrease in quality. Others delete excessive bits, but uncompressing the data afterwards will result in lower quality in comparison with the original. Compressing and uncompressing content requires a significant amount of system resources, particularly CPU processing time, therefore every web hosting platform that employs compression in real time must have ample power to support that feature. An example how info can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" what number of consecutive 1s or 0s there should be instead of storing the entire code.

Data Compression in Shared Hosting

The compression algorithm which we work with on the cloud internet hosting platform where your new shared hosting account shall be created is named LZ4 and it is applied by the state-of-the-art ZFS file system which powers the system. The algorithm is greater than the ones other file systems work with because its compression ratio is higher and it processes data a lot quicker. The speed is most noticeable when content is being uncompressed since this happens at a faster rate than data can be read from a hard drive. Therefore, LZ4 improves the performance of each and every site hosted on a server that uses this algorithm. We take full advantage of LZ4 in an additional way - its speed and compression ratio let us make several daily backups of the entire content of all accounts and store them for thirty days. Not only do these backups take less space, but their generation does not slow the servers down like it often happens with many other file systems.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting plans that we provide are created on a powerful cloud hosting platform that runs on the ZFS file system. ZFS works with a compression algorithm called LZ4 that outperforms 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 more quickly than it would be to read uncompressed data from a hard disk and as a result, sites running on a platform where LZ4 is enabled will function faster. We can take advantage of the feature despite of the fact that it needs quite a great deal of CPU processing time as our platform uses a huge number of powerful servers working together and we never create accounts on a single machine like many companies do. There's a further reward of using LZ4 - since it compresses data really 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 an entire month. This way, you'll always be able to recover any content that you delete by mistake.
