Data compression is the compacting of data by decreasing the number of bits that are stored or transmitted. Because of this, the compressed data needs much less disk space than the initial one, so extra content could be stored using the same amount of space. There are various compression algorithms which work in different ways and with several of them only the redundant bits are erased, so once the data is uncompressed, there is no decrease in quality. Others delete excessive bits, but uncompressing the data later will lead to lower quality compared to the original. Compressing and uncompressing content takes a large amount of system resources, particularly CPU processing time, so any hosting platform which employs compression in real time needs to have enough power to support this attribute. An example how data can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" how many sequential 1s or 0s there should be instead of saving the whole code.

Data Compression in Shared Hosting

The cloud internet hosting platform where your shared hosting account is created uses the cutting-edge ZFS file system. The LZ4 compression method that the latter employs is greater in various aspects, and not only does it compress information better than any compression method which some other file systems use, but it is also faster. The gains are significant particularly on compressible content like website files. Although it may sound irrational, uncompressing data with LZ4 is faster than reading uncompressed data from a hard disk drive, so the performance of every site hosted on our servers will be better. The better and faster compression rates also make it possible for us to produce numerous daily backups of the entire content in each and every web hosting account, so should you delete anything by mistake, the last back-up copy that we have will not be more than several hours old. This is possible because the backups take much less space and their generation is fast enough, so as to not influence the performance of our servers.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting 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 greater than any other algorithm these days in terms of speed and data compression ratio when it comes to processing website 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 because of this, websites running on a platform where LZ4 is present will function faster. We're able to take advantage of this feature although it needs quite a considerable amount of CPU processing time as our platform uses numerous powerful servers working together and we don't create accounts on a single machine like the vast majority of companies do. There's an additional reward of using LZ4 - since it compresses data rather 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 30 days. That way, you will always be able to restore any content that you delete by mistake.
