The term data compression identifies reducing the number of bits of information which needs to be saved or transmitted. This can be achieved with or without the loss of info, so what will be deleted at the time of the compression shall be either redundant data or unnecessary one. When the data is uncompressed afterwards, in the first case the content and the quality will be identical, whereas in the second case the quality shall be worse. You will find different compression algorithms which are more efficient for different sort of info. Compressing and uncompressing data often takes a lot of processing time, which means that the server executing the action should have enough resources in order to be able to process the data quick enough. An example how information can be compressed is to store just how many sequential positions should have 1 and how many should have 0 inside the binary code instead of storing the particular 1s and 0s.

Data Compression in Cloud Hosting

The cloud internet hosting platform where your cloud hosting account shall be created uses the outstanding ZFS file system. The LZ4 compression method that the latter uses is greater in lots of aspects, and not only does it compress data better than any compression method that a number of other file systems use, but it's also a lot quicker. The gains can be significant particularly on compressible content which includes website files. Although it could 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 shall be upgraded. The better and quicker compression rates also make it possible for us to generate numerous daily backups of the entire content in each web hosting account, so in the event you delete something by mistake, the last backup that we have will not be more than several hours old. This can be done as the backups take a lot less space and their generation is fast enough, to not affect the performance of our servers.

Data Compression in Semi-dedicated Servers

Your semi-dedicated server account will be created on a cloud platform that is run on the state-of-the-art ZFS file system. The aforementioned uses a compression algorithm known as LZ4, that is much better than all the other algorithms in terms of compression ratio and speed. The gain is visible especially when data is being uncompressed and not only is LZ4 a lot faster than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a HDD. This is why sites running on a platform which employs LZ4 compression perform better because the algorithm is most efficient when it processes compressible data i.e. web content. An additional advantage of using LZ4 is that the backups of the semi-dedicated accounts that we keep need less space and they're generated a lot quicker, which enables us to have a couple of daily backups of your files and databases.
