The term data compression means lowering the number of bits of data which should be stored or transmitted. This can be achieved with or without the loss of data, so what will be erased at the time of the compression shall be either redundant data or unnecessary one. When the data is uncompressed later on, in the first case the data and its quality will be identical, while in the second case the quality shall be worse. There're different compression algorithms that are more effective for various sort of info. Compressing and uncompressing data usually takes plenty of processing time, which means that the server carrying out the action should have ample resources to be able to process your info fast enough. A simple example how information can be compressed is to store just how many consecutive positions should have 1 and how many should have 0 in the binary code as an alternative to storing the actual 1s and 0s.

Data Compression in Shared Hosting

The cloud hosting platform where your shared hosting account shall be created uses the outstanding ZFS file system. The LZ4 compression method that the latter employs is superior in lots of aspects, and not only does it compress information better than any compression method that a variety of other file systems use, but it's also much faster. The gains are significant in particular on compressible content like website files. Although it may sound irrational, uncompressing data with LZ4 is quicker than reading uncompressed info from a hard disk drive, so the performance of each site hosted on our servers will be upgraded. The better and faster compression rates also allow us to generate multiple daily backups of the full content in every single web hosting account, so if you delete something by mistake, the last backup that we have won't be more than a few hours old. This can be done as the backups take much less space and their generation is quick enough, to not affect the performance of the servers.
