Data compression is the compacting of info by lowering the number of bits that are stored or transmitted. As a result, the compressed data takes less disk space than the original one, so much more content can be stored using the same amount of space. There're many different compression algorithms that function in different ways and with a number of them just the redundant bits are removed, therefore once the data is uncompressed, there's no loss of quality. Others erase excessive bits, but uncompressing the data later will lead to lower quality in comparison with the original. Compressing and uncompressing content needs a significant amount of system resources, particularly CPU processing time, so any Internet hosting platform that uses compression in real time needs to have adequate power to support this attribute. An example how info can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" how many consecutive 1s or 0s there should be instead of keeping the actual code.

Data Compression in Shared Website Hosting

The compression algorithm which we work with on the cloud web hosting platform where your new shared website hosting account will be created is named LZ4 and it's used by the cutting-edge ZFS file system that powers the system. The algorithm is better than the ones other file systems work with as its compression ratio is much higher and it processes data a lot quicker. The speed is most noticeable when content is being uncompressed as this happens quicker than information can be read from a hard drive. Therefore, LZ4 improves the performance of every site stored on a server that uses this particular algorithm. We take full advantage of LZ4 in an additional way - its speed and compression ratio let us produce multiple daily backups of the full content of all accounts and store them for 30 days. Not only do these backups take less space, but their generation will not slow the servers down like it can often happen with various other file systems.

Data Compression in Semi-dedicated Servers

The semi-dedicated server plans that we provide are created on a powerful cloud platform which runs on the ZFS file system. ZFS uses a compression algorithm called LZ4 that is better than any other algorithm you will find in terms of speed and compression ratio when it comes to processing website content. This is valid especially when data is uncompressed because LZ4 does that much faster than it would be to read uncompressed data from a hard drive and owing to this, sites running on a platform where LZ4 is present will work quicker. We are able to take advantage of this feature regardless of the fact that it requires quite a large amount of CPU processing time as our platform uses a number of powerful servers working together and we do not make accounts on a single machine like a lot of companies do. There is one more benefit of using LZ4 - considering that it compresses data really well and does that very quickly, 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. By doing this, you will always be able to recover any content that you delete by mistake.
