Data compression is the compacting of data by decreasing the number of bits that are stored or transmitted. Consequently, the compressed information takes substantially less disk space than the original one, so more content might be stored using the same amount of space. There are different compression algorithms which work in different ways and with several of them only the redundant bits are erased, therefore once the data is uncompressed, there's no decrease in quality. Others remove excessive bits, but uncompressing the data later will lead to lower quality compared to the original. Compressing and uncompressing content requires a significant amount of system resources, and in particular CPU processing time, so each and every hosting platform that employs compression in real time should have enough 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 Cloud Website Hosting

The cloud internet hosting platform where your cloud website hosting account shall be created uses the advanced ZFS file system. The LZ4 compression method that the latter employs is greater in lots of aspects, and not only does it compress info better than any compression method which some other file systems use, but it's also much quicker. The gains can be significant especially on compressible content which includes website files. Even though it may sound irrational, uncompressing data with LZ4 is faster than reading uncompressed info from a hard drive, so the performance of each website hosted on our servers shall be better. The better and quicker compression rates also allow us to generate numerous daily backups of the full content in each and every Internet 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 can be done because the backups take a lot less space and their generation is quick enough, so as to not change 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 which runs on the ZFS file system. ZFS employs a compression algorithm called LZ4 that exceeds any other algorithm you can find in terms of speed and data 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, websites running on a platform where LZ4 is present will function at a higher speed. We're able to take full advantage of the feature although it needs quite a great deal of CPU processing time as our platform uses many powerful servers working together and we do not create accounts on a single machine like the vast majority of companies do. There's a further reward of using LZ4 - given that it compresses data really well and does that very quickly, we can also make multiple daily backups of all accounts without influencing the performance of the servers and keep them for 30 days. In this way, you will always be able to bring back any content that you erase by mistake.
