Data compression is the compacting of information by lowering the number of bits which are stored or transmitted. Thus, the compressed info needs substantially less disk space than the original one, so extra content might be stored using the same amount of space. There're various compression algorithms that function in different ways and with many of them just the redundant bits are removed, which means that once the information is uncompressed, there is no loss of quality. Others erase excessive bits, but uncompressing the data at a later time will lead to lower quality in comparison with the original. Compressing and uncompressing content requires a large amount of system resources, especially CPU processing time, so any web hosting platform which uses compression in real time needs to have sufficient power to support that feature. An example how info 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 Hosting
The cloud internet hosting platform where your hosting
account will be generated uses the reliable ZFS file system. The LZ4 compression method which the aforementioned employs is superior in many aspects, and not only does it compress information better than any compression method which many other file systems use, but it is also a lot quicker. The benefits may be significant particularly on compressible content like website files. Despite the fact that it may sound irrational, uncompressing data with LZ4 is quicker than reading uncompressed info from a hard disk, so the performance of each and every site hosted on our servers will be improved. The better and quicker compression rates also allow us to produce multiple daily backups of the whole content in each hosting account, so if you delete anything by accident, the last back-up copy which we have will not be more than several hours old. This can be done because the backups take much less space and their generation is fast enough, to not influence the performance of the servers.
Data Compression in Semi-dedicated Servers
In case you host your websites in a semi-dedicated server
account from our firm, you will be able to experience the advantages of LZ4 - the powerful compression algorithm used by the ZFS file system which is behind our advanced cloud web hosting platform. What differentiates LZ4 from all the other algorithms out there is that it has an improved compression ratio and it is considerably faster, particularly when it comes to uncompressing web content. It does that even quicker than uncompressed data can be read from a hard disk drive, so your sites will perform faster. The higher speed comes at the expense of using plenty of CPU processing time, which is not a problem for our platform since it consists of numerous clusters working together. Along with the better performance, you'll have multiple daily backups at your disposal, so you can recover any deleted content with just a couple of clicks. The backup copies are available for a whole month and we can afford to keep them as they take considerably less space compared to ordinary backups.
