Data compression is the compacting of information by lowering the number of bits that are stored or transmitted. Because of this, the compressed info will need considerably less disk space than the initial one, so more content could be stored on the same amount of space. You will find different compression algorithms which function in different ways and with a number of them only the redundant bits are erased, so once the data is uncompressed, there's no decrease in quality. Others delete unnecessary bits, but uncompressing the data later will result in lower quality compared to the original. Compressing and uncompressing content needs a large amount of system resources, in particular CPU processing time, therefore each and every web hosting platform that uses compression in real time should have sufficient power to support this feature. An example how info can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" what number of sequential 1s or 0s there should be instead of storing the whole code.
Data Compression in Shared Hosting
The cloud internet hosting platform where your shared hosting account will be generated uses the impressive ZFS file system. The LZ4 compression method that the aforementioned uses is greater in lots of aspects, and not only does it compress info better than any compression method that similar file systems use, but it is also considerably faster. The benefits can be significant particularly on compressible content which includes website files. While it may sound unreasonable, uncompressing data with LZ4 is faster than reading uncompressed data from a hard drive, so the performance of any site hosted on our servers shall be better. The better and faster compression rates also allow us to make a number of daily backups of the entire content in each and every hosting account, so in the event you delete anything by mistake, the last backup which we have will not be more than several hours old. This is possible as the backups take much less space and their generation is fast enough, so as to not affect the performance of our servers.
Data Compression in Semi-dedicated Hosting
If you host your websites in a semi-dedicated hosting account with our company, you'll 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 separates LZ4 from all other algorithms out there is that it has a higher compression ratio and it is considerably faster, in particular with regard to uncompressing website content. It does that even quicker than uncompressed information can be read from a hard disk drive, so your websites will perform faster. The higher speed comes at the expense of using a great deal of CPU processing time, that is not an issue for our platform because it consists of multiple clusters working together. Besides the superior performance, you'll have multiple daily backups at your disposal, so you can recover any deleted content with just a couple of clicks. The backups are available for a whole month and we can afford to keep them as they need considerably less space than ordinary backups.
