Data compression is the compacting of data by lowering the number of bits which are stored or transmitted. In this way, the compressed information requires less disk space than the initial one, so more content might be stored using identical amount of space. You can find many different compression algorithms that work in different ways and with a number of them only the redundant bits are erased, therefore once the data is uncompressed, there's no loss of quality. Others remove excessive bits, but uncompressing the data at a later time will result in lower quality in comparison with the original. Compressing and uncompressing content takes a large amount of system resources, particularly CPU processing time, so each and every hosting platform that uses compression in real time must have ample power to support that attribute. 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 saving the actual code.
Data Compression in Hosting
The cloud internet hosting platform where your hosting
account will be created employs the impressive ZFS file system. The LZ4 compression method that the latter employs is greater in a number of aspects, and not only does it compress data better than any compression method that other file systems use, but it is also much quicker. The gains may be significant especially on compressible content like website files. Although it could sound illogical, uncompressing data with LZ4 is faster than reading uncompressed info from a hard disk drive, so the performance of each and every Internet site hosted on our servers shall be enhanced. The better and quicker compression rates also allow us to produce a number of daily backups of the full content in each hosting account, so in the event you delete something by mistake, the last back-up copy which we have will not be more than a few hours old. This can be done as the backups take a lot less space and their generation is fast enough, so as to not affect the performance of the servers.
