Data compression is the compacting of data by lowering the number of bits which are stored or transmitted. As a result, the compressed information will require much less disk space than the initial one, so additional content could be stored on identical amount of space. You can find different compression algorithms which work in different ways and with a lot of them just the redundant bits are erased, so once the data is uncompressed, there's no loss of quality. Others delete unneeded bits, but uncompressing the data afterwards will result in reduced quality in comparison with the original. Compressing and uncompressing content consumes a huge amount of system resources, particularly CPU processing time, so any Internet hosting platform that uses compression in real time should have enough power to support this attribute. An example how info can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" how many consecutive 1s or 0s there should be instead of saving the entire code.
Data Compression in Website Hosting
The ZFS file system which is run on our cloud Internet hosting platform uses a compression algorithm identified as LZ4. The latter is significantly faster and better than every other algorithm you'll find, particularly 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 sites hosted on ZFS-based platforms. Since the algorithm compresses data very well and it does that quickly, we can generate several backups of all the content stored in the website hosting accounts on our servers daily. Both your content and its backups will need less space and since both ZFS and LZ4 work very quickly, the backup generation will not affect the performance of the hosting servers where your content will be kept.
Data Compression in Semi-dedicated Servers
The semi-dedicated server plans that we supply are created on a powerful cloud hosting platform that runs on the ZFS file system. ZFS employs a compression algorithm known as LZ4 that is superior to any other algorithm out there in terms of speed and data compression ratio when it comes to processing website content. This is valid especially when data is uncompressed because LZ4 does that more rapidly than it would be to read uncompressed data from a hard disk and because of this, Internet sites running on a platform where LZ4 is present will work faster. We can take advantage of the feature despite of the fact that it needs quite a lot of CPU processing time because our platform uses numerous powerful servers working together and we do not create accounts on a single machine like the vast majority of companies do. There's an additional advantage of using LZ4 - considering that it compresses data rather well and does that speedily, we can also generate several daily backups of all accounts without affecting the performance of the servers and keep them for an entire month. In this way, you can always recover any content that you delete by accident.
