Data compression is the compacting of information by decreasing the number of bits which are stored or transmitted. As a result, the compressed data needs considerably less disk space than the initial one, so additional content could be stored using identical amount of space. You can find different compression algorithms that work in different ways and with some of them only the redundant bits are erased, so once the information is uncompressed, there's no loss of quality. Others remove excessive bits, but uncompressing the data later on will lead to reduced quality in comparison with the original. Compressing and uncompressing content needs a large amount of system resources, especially CPU processing time, so any Internet hosting platform which employs compression in real time needs to have sufficient power to support this attribute. An example how data can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" the number of sequential 1s or 0s there should be instead of storing the entire code.
Data Compression in Website Hosting
The cloud web hosting platform where your website hosting
account will be made employs the advanced ZFS file system. The LZ4 compression method that the latter employs is superior in numerous aspects, and not only does it compress information better than any compression method which similar file systems use, but it is also faster. The gains will be significant especially on compressible content such as website files. Despite the fact that it could sound illogical, uncompressing data with LZ4 is faster than reading uncompressed info from a hard drive, so the performance of any website hosted on our servers will be better. The better and quicker compression rates also allow us to produce numerous daily backups of the full content in every single Internet hosting account, so in the event you delete anything by accident, the last backup which we have won't be more than a few hours old. This can be done because the backups take significantly less space and their generation is fast enough, to not influence the performance of the servers.
Data Compression in Semi-dedicated Servers
The semi-dedicated server
plans that we provide are created on a powerful cloud hosting platform that runs on the ZFS file system. ZFS employs a compression algorithm named LZ4 that is better than any other algorithm on the market in terms of speed and compression ratio when it comes to processing web content. This is valid particularly when data is uncompressed since LZ4 does that faster than it would be to read uncompressed data from a hard disk drive and owing to this, Internet sites running on a platform where LZ4 is enabled will work quicker. We are able to take full advantage of this feature regardless of the fact that it needs quite a lot of CPU processing time as our platform uses numerous powerful servers working together and we don't create accounts on a single machine like most companies do. There's a further advantage of using LZ4 - since it compresses data really well and does that extremely fast, 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 recover any content that you erase by mistake.
