Data compression is the compacting of info by decreasing the number of bits which are stored or transmitted. Because of this, the compressed info requires considerably less disk space than the original one, so more content could be stored using the same amount of space. There are different compression algorithms that work in different ways and with many of them only the redundant bits are erased, so once the info is uncompressed, there's no decrease in quality. Others erase unnecessary bits, but uncompressing the data afterwards will result in reduced quality in comparison with the original. Compressing and uncompressing content takes a large amount of system resources, especially CPU processing time, therefore each and every web hosting platform which employs compression in real time needs to have sufficient power to support this feature. An example how information 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 saving the whole code.

Data Compression in Hosting

The cloud hosting platform where your hosting account is generated employs the advanced ZFS file system. The LZ4 compression method which the aforementioned uses is greater in many aspects, and not only does it compress data better than any compression method which a number of other file systems use, but it's also a lot faster. The gains may be significant especially on compressible content such as website files. Even though it could sound irrational, uncompressing data with LZ4 is quicker than reading uncompressed data from a hard drive, so the performance of every Internet site hosted on our servers shall be enhanced. The better and quicker compression rates also make it possible for us to produce a number of daily backups of the whole content in each hosting account, so should you delete anything by mistake, the last backup that we have will not be more than several hours old. This is possible because the backups take much less space and their generation is fast enough, so as to not influence the performance of the servers.

Data Compression in Semi-dedicated Hosting

Your semi-dedicated hosting account will be created on a cloud platform which runs on the state-of-the-art ZFS file system. The latter uses a compression algorithm called LZ4, which is a lot better than alternative algorithms in terms of compression ratio and speed. The gain is visible especially when data is being uncompressed and not only is LZ4 quicker than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a hard disk drive. Because of this Internet sites running on a platform which employs LZ4 compression perform faster since the algorithm is most effective when it processes compressible data i.e. site content. Another advantage of using LZ4 is that the backup copies of the semi-dedicated accounts that we keep take less space and they are generated quicker, which allows us to have multiple daily backups of your files and databases.
