Data compression is the compacting of info by lowering the number of bits that are stored or transmitted. As a result, the compressed info will require less disk space than the initial one, so much more content could be stored on identical amount of space. You will find various compression algorithms that work in different ways and with a lot of them only the redundant bits are erased, which means that once the data is uncompressed, there is no loss of quality. Others remove unnecessary bits, but uncompressing the data later will result in reduced quality compared to the original. Compressing and uncompressing content needs a huge amount of system resources, in particular CPU processing time, therefore each and every web hosting platform which uses compression in real time needs to have adequate 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 consecutive 1s or 0s there should be instead of storing the whole code.

Data Compression in Cloud Web Hosting

The cloud hosting platform where your cloud web hosting account is made uses the reliable ZFS file system. The LZ4 compression method that the latter uses is better in many 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 may be significant particularly on compressible content which includes website files. Despite the fact that it could sound illogical, uncompressing data with LZ4 is faster than reading uncompressed data from a hard disk, so the performance of any Internet site hosted on our servers will be enhanced. The better and faster compression rates also allow us to generate numerous daily backups of the entire content in each and every Internet hosting account, so should you delete anything by mistake, the last backup which we have will not be more than several hours old. This is possible because the backups take significantly less space and their generation is fast enough, so as to not influence the performance of the servers.

Data Compression in Semi-dedicated Servers

The ZFS file system which runs on the cloud platform where your semi-dedicated server account will be created uses a powerful compression algorithm called LZ4. It is among the best algorithms out there and certainly the most efficient one when it comes to compressing and uncompressing website content, as its ratio is very high and it can uncompress data much faster than the same data can be read from a hard disk drive if it were uncompressed. This way, using LZ4 will speed up any Internet site that runs on a platform where the algorithm is present. This high performance requires lots of CPU processing time, which is provided by the multitude of clusters working together as a part of our platform. What's more, LZ4 allows us to generate several backup copies of your content every day and save them for a month as they will take a reduced amount of space than standard backups and will be generated much quicker without loading the servers.
