Data compression is the compacting of information by lowering the number of bits that are stored or transmitted. As a result, the compressed data will require less disk space than the initial one, so a lot more content might be stored using identical amount of space. You will find different compression algorithms which function in different ways and with some of them just the redundant bits are erased, therefore once the data is uncompressed, there's no loss of quality. Others delete excessive bits, but uncompressing the data subsequently will result in lower quality compared to the original. Compressing and uncompressing content takes a large amount of system resources, in particular CPU processing time, so each and every hosting platform that uses compression in real time should have enough power to support that feature. An example how data can be compressed is to replace 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 Shared Hosting

The ZFS file system which is run on our cloud Internet hosting platform uses a compression algorithm identified as LZ4. The aforementioned is significantly faster and better than any other algorithm available on the market, especially for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data faster than it is read from a hard disk, which improves the performance of Internet sites hosted on ZFS-based platforms. Due to the fact that the algorithm compresses data really well and it does that very quickly, we can generate several backup copies of all the content kept in the shared hosting accounts on our servers on a daily basis. Both your content and its backups will need less space and since both ZFS and LZ4 work extremely fast, the backup generation will not affect the performance of the hosting servers where your content will be kept.

Data Compression in Semi-dedicated Hosting

The ZFS file system which runs on the cloud platform where your semi-dedicated hosting account will be created uses a powerful compression algorithm called LZ4. It is among the best algorithms out there and definitely the most efficient one when it comes to compressing and uncompressing web content, as its ratio is very high and it will uncompress data at a faster rate than the same data can be read from a hard disk drive if it were uncompressed. In this way, using LZ4 will quicken any kind of website that runs on a platform where the algorithm is enabled. This high performance requires lots of CPU processing time, that is provided by the great number of clusters working together as a part of our platform. In addition, LZ4 enables us to generate several backups of your content every day and save them for a month as they'll take much less space than typical backups and will be generated considerably faster without loading the servers.
