Data compression is the compacting of info by lowering the number of bits which are stored or transmitted. This way, the compressed information needs considerably less disk space than the original one, so more content might be stored on the same amount of space. There are different compression algorithms that work in different ways and with a lot of them just the redundant bits are erased, which means that once the information is uncompressed, there is no loss of quality. Others remove unneeded bits, but uncompressing the data subsequently will result in reduced quality in comparison with the original. Compressing and uncompressing content takes a huge amount of system resources, particularly CPU processing time, so each and every hosting platform which uses compression in real time should have sufficient power to support this attribute. An example how information can be compressed is to replace 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 whole code.

Data Compression in Web Hosting

The cloud web hosting platform where your web hosting account shall be generated uses the reliable ZFS file system. The LZ4 compression method that the aforementioned employs is greater in many aspects, and not only does it compress information better than any compression method which some other file systems use, but it's also considerably faster. The benefits are significant particularly on compressible content like website files. While it may sound illogical, uncompressing data with LZ4 is faster than reading uncompressed data from a hard disk, so the performance of each and every website hosted on our servers will be boosted. The better and faster compression rates also make it possible for us to make numerous daily backups of the entire content in every single web hosting account, so in the event you delete something by mistake, the last back-up copy which we have will not be more than a few hours old. This is possible because the backups take much less space and their generation is fast enough, to not affect the performance of the servers.
