Data compression is the compacting of data by reducing the number of bits that are stored or transmitted. Thus, the compressed data needs much less disk space than the initial one, so a lot more content could be stored on identical amount of space. You will find various compression algorithms which work in different ways and with a number of them only the redundant bits are erased, which means that once the info is uncompressed, there is no decrease in quality. Others erase unnecessary bits, but uncompressing the data later on will result in lower quality in comparison with the original. Compressing and uncompressing content takes a huge amount of system resources, especially CPU processing time, therefore each and every web hosting platform that uses compression in real time must have sufficient power to support that feature. An example how info can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" how many consecutive 1s or 0s there should be instead of saving the entire code.
Data Compression in Shared Website Hosting
The cloud web hosting platform where your shared website hosting account shall be generated uses the innovative ZFS file system. The LZ4 compression method that the aforementioned uses is superior in numerous aspects, and not only does it compress data better than any compression method that many other file systems use, but it's also faster. The gains can be significant especially on compressible content such as 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 every site hosted on our servers will be better. The better and faster compression rates also allow us to make a large number of daily backups of the entire content in each web hosting account, so if you delete anything 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 quick enough, so as to not affect the performance of the servers.
Data Compression in Semi-dedicated Hosting
The ZFS file system that runs on the cloud platform where your semi-dedicated hosting account will be created uses a powerful compression algorithm called LZ4. It's one of the best algorithms out there and positively the best one when it comes to compressing and uncompressing web content, as its ratio is very high and it'll uncompress data at a faster rate than the same data can be read from a hard disk drive if it were uncompressed. In this way, using LZ4 will speed up every site that runs on a platform where the algorithm is enabled. This high performance requires a lot of CPU processing time, which is provided by the great number of clusters working together as part of our platform. Furthermore, LZ4 makes it possible for us to generate several backups of your content every day and keep them for a month as they will take much less space than standard backups and will be generated much quicker without loading the servers.
