The term data compression means decreasing the number of bits of data which needs to be stored or transmitted. This can be achieved with or without the loss of info, so what will be deleted in the course of the compression shall be either redundant data or unnecessary one. When the data is uncompressed subsequently, in the first case the data and its quality will be identical, whereas in the second case the quality shall be worse. You can find different compression algorithms which are more efficient for various kind of info. Compressing and uncompressing data frequently takes lots of processing time, which means that the server carrying out the action should have adequate resources to be able to process the data fast enough. One simple example how information can be compressed is to store how many sequential positions should have 1 and how many should have 0 within the binary code as an alternative to storing the particular 1s and 0s.

Data Compression in Cloud Hosting

The ZFS file system which runs on our cloud hosting platform employs a compression algorithm called LZ4. The aforementioned is significantly faster and better than every other algorithm on the market, especially for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data quicker than it is read from a hard drive, which improves the overall performance of Internet sites hosted on ZFS-based platforms. Because the algorithm compresses data very well and it does that very fast, we can generate several backups of all the content stored in the cloud hosting accounts on our servers daily. Both your content and its backups will require less space and since both ZFS and LZ4 work extremely fast, the backup generation will not change the performance of the hosting servers where your content will be stored.

Data Compression in Semi-dedicated Servers

If you host your Internet sites in a semi-dedicated server account with our firm, you can experience the advantages of LZ4 - the powerful compression algorithm employed by the ZFS file system which is behind our advanced cloud hosting platform. What differentiates LZ4 from all the other algorithms out there is that it has a better compression ratio and it is much quicker, particularly with regard to uncompressing website content. It does that even faster than uncompressed information can be read from a hard drive, so your Internet sites will perform faster. The higher speed is at the expense of using a lot of CPU processing time, that's not a problem for our platform as it consists of multiple clusters working together. Besides the better performance, you'll have multiple daily backups at your disposal, so you'll be able to restore any deleted content with a few clicks. The backup copies are available for an entire month and we can afford to keep them since they need significantly less space compared to ordinary backups.
