Data compression is the decrease of the number of bits that have to be saved or transmitted and this particular process is quite important in the web hosting field because data stored on hard disks is usually compressed to take less space. There are various algorithms for compressing information and they have different efficiency based on the content. Many of them remove only the redundant bits, so that no data can be lost, while others delete unnecessary bits, which leads to worse quality once the particular data is uncompressed. This process needs plenty of processing time, therefore a web hosting server needs to be powerful enough so as to be able to compress and uncompress data instantly. An example how binary code may be compressed is by "remembering" that there are five consecutive 1s, for example, as an alternative to storing all five 1s.
Data Compression in Cloud Website Hosting
The cloud web hosting platform where your cloud website hosting account is made uses the impressive ZFS file system. The LZ4 compression method that the latter employs is better in numerous aspects, and not only does it compress data better than any compression method that many other file systems use, but it's also considerably quicker. The gains may be significant particularly on compressible content like website files. While it may sound unreasonable, uncompressing data with LZ4 is quicker than reading uncompressed data from a hard disk, so the performance of each website hosted on our servers will be boosted. The better and faster compression rates also allow us to make a number of daily backups of the entire content in each web hosting account, so in the event you delete something by mistake, the last back-up copy 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 quick enough, so as to not affect the performance of the servers.
