The term data compression describes lowering the number of bits of data which needs to be stored or transmitted. This can be done with or without losing data, which means that what will be erased in the course of the compression can be either redundant data or unneeded one. When the data is uncompressed afterwards, in the first case the info and the quality will be the same, whereas in the second case the quality will be worse. There're various compression algorithms that are better for various sort of data. Compressing and uncompressing data frequently takes plenty of processing time, so the server performing the action should have enough resources in order to be able to process your info quick enough. A simple example how information can be compressed is to store how many consecutive positions should have 1 and how many should have 0 in the binary code rather than storing the particular 1s and 0s.

Data Compression in Shared Hosting

The compression algorithm that we employ on the cloud web hosting platform where your new shared hosting account will be created is called LZ4 and it's used by the advanced ZFS file system that powers the platform. The algorithm is greater than the ones other file systems employ since its compression ratio is a lot higher and it processes data considerably faster. The speed is most noticeable when content is being uncompressed as this happens even faster than data can be read from a hard disk drive. Therefore, LZ4 improves the performance of any Internet site located on a server that uses the algorithm. We take advantage of LZ4 in an additional way - its speed and compression ratio allow us to generate a couple of daily backups of the full content of all accounts and keep them for 30 days. Not only do these backups take less space, but in addition their generation doesn't slow the servers down like it often happens with various other file systems.

Data Compression in Semi-dedicated Hosting

In case you host your Internet sites in a semi-dedicated hosting account from our firm, you'll be able to experience the advantages of LZ4 - the powerful compression algorithm employed by the ZFS file system that is behind our advanced cloud web hosting platform. What separates LZ4 from all the other algorithms out there is that it has an improved compression ratio and it is way quicker, particularly with regard to uncompressing web content. It does that even faster than uncompressed data can be read from a hard disk drive, so your websites will perform better. The higher speed comes at the expense of using a lot of CPU processing time, that is not a problem for our platform as it consists of numerous clusters working together. In addition to the superior performance, you'll have multiple daily backup copies at your disposal, so you could restore any deleted content with several clicks. The backup copies are available for a whole month and we can afford to store them as they need significantly less space than standard backups.
