The term data compression means decreasing the number of bits of info which needs to be stored or transmitted. This can be achieved with or without losing info, so what will be removed throughout the compression can be either redundant data or unnecessary one. When the data is uncompressed subsequently, in the first case the data and its quality will be identical, while in the second case the quality will be worse. You can find various compression algorithms which are more efficient for different sort of data. Compressing and uncompressing data usually takes a lot of processing time, which means that the server carrying out the action should have sufficient resources to be able to process your data fast enough. One simple example how information can be compressed is to store how many sequential positions should have 1 and how many should have 0 within the binary code instead of storing the actual 1s and 0s.
Data Compression in Cloud Website Hosting
The cloud web hosting platform where your cloud website hosting
account is generated employs the cutting-edge ZFS file system. The LZ4 compression method which the latter uses is superior in numerous aspects, and not only does it compress data better than any compression method which many other file systems use, but it's also much faster. The benefits may be significant particularly on compressible content such as website files. Although it could sound unreasonable, uncompressing data with LZ4 is faster than reading uncompressed info from a hard disk drive, so the performance of each Internet site hosted on our servers will be better. The better and faster compression rates also make it possible for us to produce a number of daily backups of the whole content in each and every web hosting account, so in the event you delete anything by mistake, the last backup that we have will not be more than a couple of hours old. This can be done because the backups take considerably less space and their generation is quick enough, to not change the performance of our servers.
Data Compression in Semi-dedicated Servers
If you host your websites in a semi-dedicated server
account from our company, you will be able to experience the advantages of LZ4 - the powerful compression algorithm used by the ZFS file system that is behind our advanced cloud Internet hosting platform. What distinguishes LZ4 from all other algorithms out there is that it has an improved compression ratio and it is way quicker, in particular with regard to uncompressing website content. It does that even quicker than uncompressed data can be read from a hard drive, so your websites will perform better. The higher speed comes at the expense of using plenty of CPU processing time, that's not an issue for our platform as it consists of a large number of clusters working together. Together with the better performance, you'll have multiple daily backups at your disposal, so you could recover any deleted content with several clicks. The backups are available for an entire month and we can afford to keep them as they need significantly less space compared to standard backups.
