Data compression is the compacting of information by reducing the number of bits that are stored or transmitted. Thus, the compressed data will need substantially less disk space than the initial one, so a lot more content can be stored on identical amount of space. There're various compression algorithms which work in different ways and with a lot of them just the redundant bits are deleted, therefore once the information is uncompressed, there is no decrease in quality. Others erase unnecessary bits, but uncompressing the data later will result in lower quality compared to the original. Compressing and uncompressing content takes a large amount of system resources, especially CPU processing time, therefore any Internet hosting platform that uses compression in real time must have sufficient power to support that feature. 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 storing the entire code.

Data Compression in Cloud Hosting

The cloud web hosting platform where your cloud hosting account will be made works by using the outstanding ZFS file system. The LZ4 compression method that the aforementioned employs is superior in many aspects, and not only does it compress information better than any compression method which other file systems use, but it is also a lot quicker. The gains may be significant especially on compressible content which includes website files. Although it could sound illogical, uncompressing data with LZ4 is quicker than reading uncompressed data from a hard disk, so the performance of each Internet site hosted on our servers shall be boosted. The better and faster compression rates also make it possible for us to make a large number of daily backups of the entire content in each and every web hosting account, so in the event you delete anything by mistake, the last backup which we have will not be more than a couple of hours old. This can be done because the backups take much less space and their generation is fast enough, so as to not affect the performance of our servers.
