Data compression is the compacting of data by reducing the number of bits that are stored or transmitted. Consequently, the compressed info needs less disk space than the original one, so much more content could be stored using the same amount of space. You can find various compression algorithms which work in different ways and with several of them only the redundant bits are deleted, which means that once the information is uncompressed, there is no decrease in quality. Others erase unnecessary bits, but uncompressing the data at a later time will lead to reduced quality in comparison with the original. Compressing and uncompressing content takes a significant amount of system resources, especially CPU processing time, therefore each and every web hosting platform that employs compression in real time should have enough power to support that attribute. An example how info can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" what number of consecutive 1s or 0s there should be instead of saving the actual code.
Data Compression in Website Hosting
The cloud web hosting platform where your website hosting account is generated employs the impressive ZFS file system. The LZ4 compression method that the aforementioned uses is superior in many aspects, and not only does it compress data better than any compression method which some other file systems use, but it's also much quicker. The benefits can be significant especially on compressible content like website files. While it could sound unreasonable, uncompressing data with LZ4 is faster than reading uncompressed info from a hard disk drive, so the performance of any Internet site hosted on our servers will be boosted. The better and quicker compression rates also allow us to generate multiple daily backups of the whole content in each Internet hosting account, so in the event you delete anything by accident, the last backup which we have won't be more than several hours old. This is possible because the backups take a lot less space and their generation is fast enough, so as to not affect the performance of our servers.
